dnl Check for an OpenGL implementation. If GL is found, the required

dnl If the header "GL/gl.h" is found, "HAVE_GL_GL_H" is defined. If the

|
dnl header "OpenGL/gl.h" is found, HAVE_OPENGL_GL_H is defined. These

|
dnl preprocessor definitions may not be mutually exclusive.

dnl AX_CHECK_GLU

dnl
|
|
dnl DESCRIPTION
|
|
dnl
|
|
dnl Check for GLU. If GLU is found, the required preprocessor and linker
|
|
dnl flags are included in the output variables "GLU_CFLAGS" and "GLU_LIBS",
|
|
dnl respectively. If no GLU implementation is found, "no_glu" is set to
|
|
dnl "yes".
|
|
dnl
|
|
dnl If the header "GL/glu.h" is found, "HAVE_GL_GLU_H" is defined. If the
|
|
dnl header "OpenGL/glu.h" is found, HAVE_OPENGL_GLU_H is defined. These
|
|
dnl preprocessor definitions may not be mutually exclusive.
|
|
dnl
|
|
dnl Some implementations (in particular, some versions of Mac OS X) are
|
|
dnl known to treat the GLU tesselator callback function type as "GLvoid
|
|
dnl (*)(...)" rather than the standard "GLvoid (*)()". If the former
|
|
dnl condition is detected, this macro defines "HAVE_VARARGS_GLU_TESSCB".

dnl
|
|
dnl AX_CHECK_GLUT
|
|
dnl
|
|
dnl DESCRIPTION
|
|
dnl
|
|
dnl Check for GLUT. If GLUT is found, the required compiler and linker flags
|
|
dnl are included in the output variables "GLUT_CFLAGS" and "GLUT_LIBS",
|
|
dnl respectively. If GLUT is not found, "no_glut" is set to "yes".
|
|
dnl
|
|
dnl If the header "GL/glut.h" is found, "HAVE_GL_GLUT_H" is defined. If the
|
|
dnl header "GLUT/glut.h" is found, HAVE_GLUT_GLUT_H is defined. These
|
|
dnl preprocessor definitions may not be mutually exclusive.

dnl SYNOPSIS
|
|
dnl
|
|
dnl AX_PTHREAD([ACTION-IF-FOUND[, ACTION-IF-NOT-FOUND]])
|
|
dnl
|
|
dnl DESCRIPTION
|
|
dnl
|
|
dnl This macro figures out how to build C programs using POSIX threads. It
|
|
dnl sets the PTHREAD_LIBS output variable to the threads library and linker
|
|
dnl flags, and the PTHREAD_CFLAGS output variable to any special C compiler
|
|
dnl flags that are needed. (The user can also force certain compiler
|
|
dnl flags/libs to be tested by setting these environment variables.)
|
|
dnl
|
|
dnl Also sets PTHREAD_CC to any special C compiler that is needed for
|
|
dnl multi-threaded programs (defaults to the value of CC otherwise). (This
|
|
dnl is necessary on AIX to use the special cc_r compiler alias.)
|
|
dnl
|
|
dnl NOTE: You are assumed to not only compile your program with these flags,
|
|
dnl but also link it with them as well. e.g. you should link with
|
|
dnl $PTHREAD_CC $CFLAGS $PTHREAD_CFLAGS $LDFLAGS ... $PTHREAD_LIBS $LIBS
|
|
dnl
|
|
dnl If you are only building threads programs, you may wish to use these
|
|
dnl variables in your default LIBS, CFLAGS, and CC:
|
|
dnl
|
|
dnl LIBS="$PTHREAD_LIBS $LIBS"
|
|
dnl CFLAGS="$CFLAGS $PTHREAD_CFLAGS"
|
|
dnl CC="$PTHREAD_CC"
|
|
dnl
|
|
dnl In addition, if the PTHREAD_CREATE_JOINABLE thread-attribute constant
|
|
dnl has a nonstandard name, defines PTHREAD_CREATE_JOINABLE to that name
|
|
dnl (e.g. PTHREAD_CREATE_UNDETACHED on AIX).
|
|
dnl
|
|
dnl ACTION-IF-FOUND is a list of shell commands to run if a threads library
|
|
dnl is found, and ACTION-IF-NOT-FOUND is a list of commands to run it if it
|
|
dnl is not found. If ACTION-IF-FOUND is not specified, the default action
|
|
dnl will define HAVE_PTHREAD.
|
|
dnl
|
|
dnl Please let the authors know if this macro fails on any platform, or if
|
|
dnl you have any other suggestions or comments. This macro was based on work
|
|
dnl by SGJ on autoconf scripts for FFTW (http://www.fftw.org/) (with help
|
|
dnl from M. Frigo), as well as ac_pthread and hb_pthread macros posted by
|
|
dnl Alejandro Forero Cuervo to the autoconf macro repository. We are also
|
|
dnl grateful for the helpful feedback of numerous users.

dnl We must check for the threads library under a number of different

dnl (e.g. DEC) have both -lpthread and -lpthreads, where one of the
|
|
dnl libraries is broken (non-POSIX).
|
|
|

dnl Create a list of thread flags to try. Items starting with a "-" are

dnl none: in case threads are in libc; should be tried before -Kthread and

dnl other compiler flags to prevent continual compiler warnings
|
|
dnl -Kthread: Sequent (threads in libc, but -Kthread needed for pthread.h)
|
|
dnl -kthread: FreeBSD kernel threads (preferred to -pthread since SMP-able)
|
|
dnl lthread: LinuxThreads port on FreeBSD (also preferred to -pthread)
|
|
dnl -pthread: Linux/gcc (kernel threads), BSD/gcc (userland threads)
|
|
dnl -pthreads: Solaris/gcc
|
|
dnl -mthreads: Mingw32/gcc, Lynx/gcc
|
|
dnl -mt: Sun Workshop C (may only link SunOS threads [-lthread], but it
|
|
dnl doesn't hurt to check since this sometimes defines pthreads too;
|
|
dnl also defines -D_REENTRANT)
|
|
dnl ... -mt is also the pthreads flag for HP/aCC
|
|
dnl pthread: Linux, etcetera

dnl --thread-safe: KAI C++
