Installing wxWidgets for Windows -------------------------------- This is wxWidgets for Microsoft Windows 9x/ME, Windows NT and later (2000, XP, Vista, 7, 8, etc) including both 32 bit and 64 bit versions. Table of Contents: - Installation - Building wxWidgets - Configuring the Build - Building Applications Using wxWidgets Installation ============ If you are using one of the supported compilers, you can download the pre-built in binaries from https://sourceforge.net/projects/wxwindows/files/3.0.0/binaries/ or ftp://ftp.wxwidgets.org/pub/3.0.0/binaries/ In this case, just uncompress the binaries archive under any directory and skip to "Building Applications Using wxWidgets" part. Otherwise, or if you want to build a configuration of the library different from the default one, you need to build the library from sources before using it. The first step, which you may have already performed, unless you are reading this file online, is to download the source archive and uncompress it in any directory. It is strongly advised to avoid using spaces in the name of this directory, i.e. notably do *not* choose a location under "C:\Program Files", as this risks creating problems with makefiles and other command-line tools. After choosing the directory location, please define WXWIN environment variable containing the full path to this directory. While this is not actually required, this makes using the library more convenient and this environment variable is used in the examples below. NB: If you checked your sources from version control repository and didn't obtain them from a release file, you also need to copy include/wx/msw/setup0.h to include/wx/msw/setup.h. Building wxWidgets ================== The following sections explain how to compile wxWidgets with each supported compiler, see the "Building Applications" section about the instructions for building your application using wxWidgets. All makefiles and project are located in build\msw directory. Microsoft Visual C++ Compilation ---------------------------------------------------------------- * From command line using the provided makefiles: 0. Open a "Visual Studio Command Prompt" window shortcut to which must have been installed to the "Start" menu or the "Start" screen by MSVS installation. 1. Change directory to %WXWIN%\build\msw and type > nmake /f makefile.vc to build wxWidgets in the default debug configuration as a static library. You can also do > nmake /f makefile.vc BUILD=release to build a release version or > nmake /f makefile.vc BUILD=release SHARED=1 to build a release DLL version. Finally, you can also add "TARGET_CPU=X64" to nmake command line to build Win64 versions (this only works if you are using a 64 bit compiler, of course). See "Configuring the Build" for more information about the additional parameters that can be specified on the command line. 2. To verify your build, change the directory to samples\minimal and run the same nmake command (with the same parameters there), this should create a working minimal wxWidgets sample. 3. If you need to rebuild, use "clean" target first or "nmake /a". * From the IDE using the provided project files: Ready to use project files are provided for VC++ versions 6, 7, 8, 9, 10, 11 and 12 (also known as MSVS 6, 2003, 2005, 2008, 2010, 2012 and 2013 respectively). Simply open wx_vcN.sln (for N=7, 8, 9, 10, 11 or 12) or wx.dsw (for VC6) file, select the appropriate configuration (Debug or Release, static or DLL) and build the solution. Notice that when building a DLL configuration, you may need to perform the build several times because the projects are not always built in the correct order, and this may result in link errors. Simply do the build again, up to 3 times, to fix this. Notice that x64 configurations are only included in VC10 and later project currently. If you want to build Win64 libraries with the previous compiler versions, the simplest solution is to use the makefiles as described above. Special note for VC11 and VC12 projects: it is possible to customize the build by creating wx_vcN_local.props (N=11 or 12) file in build\msw directory which is used, if it exists, by the projects. The settings in this file override the default values for the properties such as wxCfg (corresponding to the CFG makefile variable described below) or wxVendor (corresponding to VENDOR). For example, you could set wxCompilerPrefix to "vc120" in your local properties file: vc120 to use "vc120" prefix for the build directories used by VC12 and so to allow its build files to coexist with the files produced by the other MSVC versions. Notice that by using a separate local props file you ensure that your changes won't be lost when updating to a future wxWidgets version. Cygwin/MinGW Compilation ---------------------------------------------------------------- wxWidgets supports Cygwin, MinGW, MinGW-w64 and TDM-GCC tool chains under Windows. They can be downloaded from: http://www.cygwin.com/ http://www.mingw.org/ http://mingw-w64.sourceforge.net/ http://tdm-gcc.tdragon.net/ respectively. Please retrieve and install the latest version of your preferred tool chain by following the instructions provided by these packages. Notice that Cygwin includes both native Cygwin compiler, which produces binaries that require Cygwin during run-time, and MinGW[-w64] cross-compilers which can still be used in Cygwin environment themselves but produce plain Windows binaries without any special run-time requirements. You will probably want to use the latter for developing your applications. If using MinGW, you can download the add-on MSYS package to provide Unix-like tools that you'll need to build wxWidgets using configure. C++11 note: If you want to compile wxWidgets in C++11 mode, you currently have to use -std=gnu++11 switch as -std=c++11 disables some extensions that wxWidgets relies on. I.e. please use CXXFLAGS="-std=gnu++11". All of these tool chains can be used either with Unix-like configure+make build process (preferred) or with the provided makefile.gcc makefiles without using configure: * Using configure This method works in exactly the same way as under Unix systems, including OS X, and requires a Unix-like environment to work, i.e. either MSYS or Cygwin. 0. Open MSYS or Cygwin shell prompt. 1. Create a build directory: it is is strongly recommended to not build the library in the directory containing the sources ($WXWIN) but to create a separate build directory instead. The build directory can be placed anywhere (using the fastest available disk may be a good idea), but in this example we create it as a subdirectory of the source one: $ cd $WXWIN $ mkdir build-debug 2. Run configure passing it any of the options shown by "configure --help". Notice that configure builds shared libraries by default, use --disable-shared to build static ones. For example: $ ../configure --enable-debug 3. Build the library: $ make 4. Test the library build by building the minimal sample: $ cd samples/minimal $ make 5. Optionally install the library in a global location $ make install Notice that there is not much benefice to installing under Windows so this step can usually be omitted. * Using plain makefiles: NOTE: The makefile.gcc makefiles are for compilation under MinGW using Windows command interpreter (command.com/cmd.exe), they won't work if you use Unix shell, as is the case with MSYS. Follow the instructions for using configure above instead if you prefer to use Unix shell. 0. Open DOS command line window (cmd.exe, *not* Bash sh.exe). 1. Change directory to %WXWIN%\build\msw and type > mingw32-make -f makefile.gcc to build wxWidgets in the default debug configuration as a static library. Add "BUILD=release" and/or "SHARED=1" to build the library in release configuration and/or as a shared library instead of the default static one. 2. To verify your build, change the directory to samples\minimal and run the same mingw32-make command (with the same parameters there), this should create a working minimal wxWidgets sample. 3. If you need to rebuild, use "clean" target first. Borland C++ Compilation ---------------------------------------------------------------- WARNING: Borland instructions are out of date, please send us your corrections if you are using it with wxWidgets 3.0. The minimum version required is 5.5 (last version supported by BC++ 5.0 was 2.4.2), which can be downloaded for free from: http://www.borland.com/products/downloads/download_cbuilder.html We have found that the free Turbo Explorer and commercial BDS work fine; the debugger is very good. To avoid linker errors you will need to add -DSHARED=1 to the makefile line for the library The version 5.6 included in Borland C++ Builder 2006 works as well after the following small change: please remove the test for __WINDOWS__ from line 88 of the file BCCDIR\include\stl\_threads.h. Compiling using the makefiles: 1. Change directory to build\msw. Type 'make -f makefile.bcc' to make the wxWidgets core library. Ignore the compiler warnings. This produces a couple of libraries in the lib\bcc_lib directory. 2. Change directory to a sample or demo such as samples\minimal, and type 'make -f makefile.bcc'. This produces a windows exe file - by default in the bcc_mswd subdirectory. Note (1): the wxWidgets makefiles assume dword structure alignment. Please make sure that your own project or makefile settings use the same alignment, or you could experience mysterious crashes. To change the alignment, change CPPFLAGS in build\msw\config.bcc. Note (2): If you wish debug messages to be sent to the console in debug mode, edit makefile.bcc and change /aa to /Tpe in link commands. Using the Debugger and IDE in BDS or Turbo Explorer --------------------------------------------------- Doubleclick / open samples\minimal\borland.bdsproj. The current version is to be used with a dynamic build of wxWidgets-made by running make -f Makefile.bcc -DBUILD=debug -DSHARED=1 in wxWidgets\build\msw. You also need the wxWidgets\lib\bcc_dll directory in your PATH. The debugger tracks your source and also traces into the wxWidgets sources. To use this to debug other samples, copy the borland_ide.cpp and borland.bdsproj files, then replace all occurrences of "minimal" with the name of the new project files Compilation succeeds with CBuilderX personal edition and CBuilder6, but you may have to copy make.exe from the 5.5 download to the new bin directory. Compiling using the IDE files for Borland C++ 5.0 and using CBuilder IDE (v1-v6): not supported ** REMEMBER ** In all of your wxWidgets applications, your source code should include the following preprocessor directive: #ifdef __BORLANDC__ #pragma hdrstop #endif (check the samples -- e.g., \wx2\samples\minimal\minimal.cpp -- for more details) Configuring the Build ================================================================ NOTE: If you use configure to build the library with Cygwin/MinGW, the contents of this section does not apply, just pass the arguments to configure directly in this case. Library configuration ---------------------------------------------------------------- While it is never necessary to do it, you may want to change some of the options in the include/wx/msw/setup.h file before building wxWidgets. This file is heavily commented, please read it and enable or disable the features you would like to compile wxWidgets with[out]. Notice that this file is later copied into a directory under lib for each of the build configurations which allows to have different build options for different configurations too if you edit any configuration-specific file. Makefile parameters ---------------------------------------------------------------- When building using makefiles, you can specify many build settings (unlike when using the project files where you are limited to choosing just the configuration and platform). This can be done either by passing the values as arguments when invoking make or by editing build\msw\config.$(compiler) file where $(compiler) is same extension as the makefile you use has (see below). The latter is good for setting options that never change in your development process (e.g. GCC_VERSION or VENDOR). If you want to build several versions of wxWidgets and use them side by side, the former method is better. Settings in config.* files are shared by all makefiles (including the samples), but if you pass the options as arguments, you must use same arguments you used for the library when building samples! For example, to build the library in release mode you can either change the "BUILD" variable definition in build\msw\config.$(compiler) or use > nmake -f makefile.vc BUILD=debug > mingw32-make -f makefile.gcc BUILD=debug depending on the compiler used. The full list of the build settings follows: BUILD=release Builds release version of the library. It differs from default 'debug' in lack of appended 'd' in name of library and uses the release CRT libraries instead of debug ones. Notice that even release builds do include debug information by default, see DEBUG_FLAG for more information about it. SHARED=1 Build shared libraries (DLLs). By default, DLLs are not built (SHARED=0). UNICODE=0 To completely disable Unicode support (default is UNICODE=1). It should not be necessary to do this unless, perhaps, you still wish to target Win9x systems and can't use MSLU (which requires MSLU=1) for some reason. This option affect name of the library ('u' is appended in the default Unicode build) and the directory where the library and setup.h are stored (ditto). WXUNIV=1 Build wxUniversal instead of native wxMSW (see http://www.wxwidgets.org/wxuniv.htm for more information). MONOLITHIC=1 Starting with version 2.5.1, wxWidgets has the ability to be built as several smaller libraries instead of single big one as used to be the case in 2.4 and older versions. This is called "multilib build" and is the default behaviour of makefiles. You can still build single library ("monolithic build") by setting MONOLITHIC variable to 1. USE_GUI=0 Disable building GUI parts of the library, build only wxBase components used by console applications. Note that if you leave USE_GUI=1 then both wxBase and GUI libraries are built. USE_$(LIBRARY)=0 Do not build the corresponding library (all libraries are built by default). Library which can be disabled in this way are: AUI, HTML, MEDIA, GL (the option name is USE_OPENGL for this one), PROPGRID, QA, RIBBON, RICHTEXT, STC, WEBVIEW, XRC. RUNTIME_LIBS=static Links static version of C and C++ runtime libraries into the executable, so that the program does not depend on DLLs provided with the compiler (e.g. Visual C++'s msvcrt.dll or Borland's cc3250mt.dll). Caution: Do not use static runtime libraries when building DLL (SHARED=1)! MSLU=1 Enables MSLU (Microsoft Layer for Unicode). This setting makes sense only if used together with UNICODE=1. If you want to be able to use Unicode version on Windows9x, you will need MSLU (Microsoft Layer for Unicode) runtime DLL and import lib. The former can be downloaded from Microsoft, the latter is part of the latest Platform SDK from Microsoft (see msdn.microsoft.com for details). An alternative implementation of import library can be downloaded from http://libunicows.sourceforge.net - unlike the official one, this one works with other compilers and does not require 300+ MB Platform SDK update. DEBUG_FLAG=0 DEBUG_FLAG=1 DEBUG_FLAG=2 Specifies the level of debug support in wxWidgets. Notice that this is independent from both BUILD and DEBUG_INFO options. By default always set to 1 meaning that debug support is enabled: asserts are compiled into the code (they are inactive by default in release builds of the application but can be enabled), wxLogDebug() and wxLogTrace() are available and __WXDEBUG__ is defined. Setting it to 0 completely disables all debugging code in wxWidgets while setting it to 2 enables even the time consuming assertions and checks which are deemed to be unsuitable for production environment. DEBUG_INFO=0 DEBUG_INFO=1 This option affects whether debugging information is generated. If omitted or set to 'default' its value is determined the value of the BUILD option. DEBUG_RUNTIME_LIBS=0 DEBUG_RUNTIME_LIBS=1 (VC++ only.) If set to 1, msvcrtd.dll is used, if to 0, msvcrt.dll is used. By default msvcrtd.dll is used only if the executable contains debug info and msvcrt.dll if it doesn't. It is sometimes desirable to build with debug info and still link against msvcrt.dll (e.g. when you want to ship the app to customers and still have usable .pdb files with debug information) and this setting makes it possible. TARGET_CPU=X64|IA64 (VC++ only.) Set this variable to build for x86_64 systems. If unset, x86 build is performed. VENDOR= Set this to a short string identifying your company if you are planning to distribute wxWidgets DLLs with your application. Default value is 'custom'. This string is included as part of DLL name. wxWidgets DLLs contain compiler name, version information and vendor name in them. For example wxmsw300_core_vc_custom.dll is one of DLLs build using Visual C++ with default settings. If you set VENDOR=mycorp, the name will change to wxmsw300_core_vc_mycorp.dll. CFG= Sets configuration name so that you can have multiple wxWidgets builds with different setup.h settings coexisting in same tree. The value of this option is appended to the build directories names. This is useful for building the library in some non-default configuration, e.g. you could change wxUSE_STL to 1 in include/wx/msw/setup.h and then build with "CFG=-stl". Alternatively, you could build with e.g. "RUNTIME_LIBS=static CFG=-mt" when using MSVC. COMPILER_PREFIX= If you build with multiple versions of the same compiler, you can put their outputs into directories like "vc6_lib", "vc8_lib" etc. instead of "vc_lib" by setting this variable to e.g. "vc6". This is merely a convenience variable, you can achieve the same effect (but different directory names) with the CFG option. CFLAGS CXXFLAGS CPPFLAGS LDFLAGS Additional flags to be used with C compiler, C++ compiler, C preprocessor (used for both C and C++ compilation) and linker, respectively. Building Applications Using wxWidgets ===================================== NB: The makefiles and project files provided with wxWidgets samples show which flags should be used when building applications using wxWidgets so in case of a problem, e.g. if the instructions here are out of date, you can always simply copy a makefile or project file from samples\minimal or some other sample and adapt it to your application. Independently of the compiler and make/IDE you are using you must do the following to use wxWidgets: * Add $WXWIN/include to the - compiler - resource compiler include paths. * Define the following symbols for the preprocessor: - __WXMSW__ to ensure you use the correct wxWidgets port. - _UNICODE unless you want to use deprecated ANSI build of wxWidgets. - NDEBUG if you want to build in release mode, i.e. disable asserts. - WXUSINGDLL if you are using DLL build of wxWidgets. * If using MSVC 6 or 7 only (i.e. not for later versions), also define wxUSE_RC_MANIFEST=1 and WX_CPU_X86. * Add $WXWIN/lib/prefix_lib-or-dll to the libraries path. The prefix depends on the compiler, by default it is "vc" for MSVC, "gcc" for g++ and so on. * Add the list of libraries to link with to the linker input. The exact list depends on which libraries you use and whether you built wxWidgets in monolithic or default multlib mode and basically should include all the relevant libraries from the directory above, e.g. "wxmsw30ud_core.lib wxbase30ud.lib wxtiffd.lib wxjpegd.lib wxpngd.lib wxzlibd.lib wxregexud.lib wxexpatd.lib" for a debug build of an application using the core library only (all wxWidgets applications use the base library). Microsoft Visual C++ users can simplify the linker setup by prepending the directory $WXWIN/msvc to the include path (it must come before $WXWIN/include directory!) and omitting the last step: the required libraries will be linked in automatically using the "#pragma comment(lib)" feature of this compiler.
