Only run install_name_tool on our own libraries as part of "make
install" instead of doing it on all libraries in the installation
directory: this was at best useless and at worst harmful, as some
combinations of install_name_tool and macOS versions don't work well
together and result in corrupting the already installed libraries.
Consider that all still supported/existing platforms provide these
declarations, if they provide these functions at all (and they probably
all do, so we almost certainly could remove all the test for them, but
keep them for now).
Note that we still test for broken declarations as this might still be
useful on HP-UX 11 systems, where this problem was reported "only" 8
years ago.
By not using AC_CHECK_FUNCS() we avoid the problem when using it with
snprintf() when cross-compiling with the latest MinGW API headers, see
https://sourceforge.net/p/mingw-w64/bugs/935/ for more details.
This commit is best viewed ignoring whitespace-only changes.
Although wxWidgets doesn't use any C++20 features yet, still allow
compiling it in C++ 20 mode if wanted.
Update the helper macro for detecting available C++ version support from
https://www.gnu.org/software/autoconf-archive/ax_cxx_compile_stdcxx.html
with just a minor change to de-TAB-ify it to pass our code style check
forbidding indenting with TABs.
Closes#22238.
On recent FreeBSDs, the "Linux-only" <sys/epoll.h> exists in the default
include path, and is thus detected by configure. However, the header belongs
to the epoll-shim emulation library, and it is doubtful whether using it
on FreeBSD is a good idea. Therefore check that the operating system
is actually Linux before enabling wxEpollDispatcher.
Closes#22146.
src/unix/mediactrl.cpp failed to compile due to a precision-losing cast
(from 'gpointer' {aka 'void*'} to 'window_id_type' {aka 'unsigned int'}).
Tell pkg-config to use 64-bit configs if building for 64-bit on SunOS.
PKG_CONFIG_PATH is set to /usr/lib/64/pkgconfig in that case.

Don't say that it's only for MSW and GTK 3, as it's also available under
Mac. Also don't use "spellchecking" non-word in the description of a
spell-checking option.
No real changes.
Check for Direct2D headers (only, as DLLs are loaded during run-time
anyhow) and enable Direct2D-based wxGraphicsContext implementation if
they are available when building wxMSW with configure.
It's not really useful to warn that spell checking is not available for
the ports for which it's not implemented anyhow, as there is nothing
that the person running configure can do about it anyhow.
Still warn about missing gtkspell library when using GTK 3, however, as
it may be useful to know that it's not available and could be installed
in order to activate spell checking support.
The wxrc program does not depend on the GUI libraries, but only on
the base and XML libraries, so make it possible to build it in non-GUI
builds too.
Closes https://github.com/wxWidgets/wxWidgets/pull/2419
The latter two are always defined in sys/types.h on all Unix systems and
we already define them for MSVC (which doesn't use configure anyhow).
The former type is always defined everywhere.
This type should always be defined in sys/types.h on any non-ancient
Unix system, so don't bother checking for it, which is not only wasteful
but can even be harmful because it can conflict with pid_t definitions
in the other libraries under Windows, where we (wrongly) define it as
int (which is actually a bug in autoconf, which was recently fixed, see
https://savannah.gnu.org/support/index.php?110296) when using CMake.
So just don't define it at all: it should be already defined under Unix
and we don't use it under MSW anyhow.
See https://github.com/microsoft/vcpkg/issues/19110
See #18150.
The case of missing strtod_l() is already handled by 9507bc430e
(Determine availability of the required xlocale API by compiling,
2017-04-14).
Similarly test for all the strto*_l() functions used by wx instead of
assuming that they are available if strtod_l() is.
It appears that the 'musl' C standard library, used on e.g. Alpine
Linux, does have strtod_l(), but not the others. Because of which this
check did not properly disable the feature, and compilation would fail.
Closes https://github.com/wxWidgets/wxWidgets/pull/2451
Make configure behaviour consistent with CMake the default value of 0
for wxUSE_LIBLZMA in setup.h under MSW.
This also means that dependency on the system liblzma is not picked up
by default when --disable-sys-libs configure option is used, as this was
rather unexpected.
Replace the use of Henry Spencer's regex library with PCRE at the build
level and enable wxUSE_PCRE in wxRegEx code to switch to PCRE-based
implementation there.
Note that this has to be done unconditionally because there is no simple
way to select between the previously used regex library and PCRE at the
makefiles level.
We could still keep the possibility to use the system regex library
under Unix, but this doesn't seem to be worth doing, as we don't support
Unicode REs properly when using it (and never did), so drop support for
this too.
This is another library that can be detected and used by libtiff
configure that we don't want to use, as built-in libraries shouldn't
have any external dependencies, so explicitly disable its use, just as
it was already done for libjbig, libwebp and libzstd, see ec4b71afa0
(Update tiff submodule, 2018-11-17) and b7600b0b1b (Ensure jbig support
is disabled for builtin libtiff, 2020-06-17).
Closes https://github.com/wxWidgets/wxWidgets/pull/2394
In addition to linking with Winsock 2, also use winsock2.h.
This allows to turn on IPv6 support on by default under MSW, so turn it
on under Unix too for consistency.
Predefine _WINSOCK_DEPRECATED_NO_WARNINGS to avoid warnings about
deprecated (but still available and very unlikely to be ever removed)
Winsock 1 functions that we still use.
This check didn't work in configure when using C++17 or later, as
std::bind2nd() is removed in C++17 and so was worse than useless as it
actually prevented --enable-stl from working.
And while it was only done when using C++98 in CMake, it still seems
pretty useless there too as there should be no environments in which
basic stuff like std::vector<> or std::find_if() is not available.
So just remove it entirely.
When configured with --enable-permissive option, add -fpermissive to C++
flags, not C flags, to avoid the gcc warning
command-line option '-fpermissive' is valid for C++/ObjC++ but not for C
when compiling C code.
Closes https://github.com/wxWidgets/wxWidgets/pull/2232
Only disable using the system libraries when a built-in version is
available, otherwise still use the system library as this seems more
useful than disabling the use of only some system libraries (liblzma and
libcurl), while still possibly depending on dozens more via GTK.
Update the documentation and remove the now unnecessary --with-libcurl
from the CI script.
Closes https://github.com/wxWidgets/wxWidgets/pull/2208
Don't add both a directory and its subdirectories to SAMPLES_SUBDIRS as
this can result in 2 sub-makes building in the same directory in
parallel: one make process recursing into sub-subdirectory from the
subdirectory and another one running directly inside it. This notably
results in recurring failures in GitHub Actions CI builds.
We still need to create makefile.in in the subdirectories containing
other samples, so add a separate SAMPLES_SUBTREES variable and use it to
collect such directories, instead of putting them into SAMPLES_SUBDIRS
itself.
Don't use system libcurl if --disabled-sys-libs was used, but warn about
it as this could be unexpected.
We could consider including libcurl as submodule, and use the built-in
version as a fallback, but it's a relatively big repository (100MiB+),
so it's not clear if it would be a good idea to do it.
Just sort the features in the same section in alphabetical order to make
it easier to find the given feature in the list (or confirm that it is
not present).
No real changes.
Since Apple clang version 12 implicit function declarations by default
are (rightfully) an error resulting in failure to compile the configure
tests for libpng and zlib, which make implicit use of exit.
Fix by using return statements (another solution is including stdlib.h).
Only use wxUSE_WEBREQUEST_{URLSESSION,WINHTTP} under the platforms where
they make sense.
Turn wxUSE_WEBREQUEST off if no backends are available and warn about
it, even under MSW/macOS platforms where this wasn't done previously.
It was never defined because USE_WIN32 wasn't set at the time it was
tested. Fix this by just always defining this option, even though it
only makes sense for MSW.
Also fix the test for winhttp.h, it needs to include windows.h first, as
otherwise compiling the header would always fail.
Using build system libraries for a different host doesn't make sense and
can be actively harmful, so set PKG_CONFIG_LIBDIR to prevent pkg-config
from finding them (it, or PKG_CONFIG_PATH, can still be set to some
host-appropriate directory manually before/when running configure).
This obviates the need for the changes in the previous commit, so revert
it.
Using --with is more appropriate for libcurl and WinHTTP as they
introduce dependencies on external libraries and is done for
NSURLSession too for consistency.
And there doesn't seem to be any real reason to make these options names
longer by including "webrequest" in their names, they're clear and
unambiguous enough even without it.
This is mostly useful for disabling the use of WinHTTP, e.g. because
only libcurl-based backend will be used or because WinHTTP headers or
libraries are not available and so using it would fail in any case.
This is simpler and better (supports cross-compiling, manual override,
...) than doing it manually.
Also disable wxWebRequest completely under Unix if libcurl was not
found, as it's the only backend which can be used on non-MSW/Mac
platforms.
