Hi Ben,
I think I got it. I did some more Internet search and found a nice
implementation that (from my point of view) is not the way how we
should do it:
#if defined(__APPLE_CC__) && __APPLE_CC__ > 4000 &&
__APPLE_CC__ < 5450 && !defined(__INTEL_COMPILER)
typedef GLvoid (*GLUTesselatorFunction)(...);
#elif defined( __mips ) || defined( __linux__ ) ||
defined( __FreeBSD__ ) ||
defined( __OpenBSD__ ) || defined( __sun ) || defined (__CYGWIN__)
||
defined (__APPLE__)
typedef GLvoid (*GLUTesselatorFunction)();
<SNIP>
but there are also some good implementations for this problem, eg.
http://autoconf-archive.cryp.to/ax_check_glu.html
I created another macro "OCTAVE_GLUTESSCALLBACK_THREEDOTS" that is
called if a valid framework OpenGL is found. It separates the way of
calling gluTessCallback on our different Mac systems.
I attached a script "configure.in" to this email, can you please try
this on your system (there are some files created while doing
autoheader and autoconf, so the best would be if you put
configure.in into /tmp and work there):
bash$ autoheader && autoconf && ./configure
The relevant output on my machine that should be checked on your Mac
is:
checking whether ld accepts -framework OpenGL... yes
configure: adding -Wl,-framework -Wl,OpenGL to OPENGL_LIBS
checking whether gluTessCallback is called with "(...)"... yes
OPENGL_LIBS: -Wl,-framework -Wl,OpenGL
On your Mac it should be "checking whether gluTessCallback is called
with "(...)"... no". The second test is
$ autoheader && autoconf && ./configure
checking for g++... g++
checking for C++ compiler default output file name... a.out
checking whether the C++ compiler works... yes
checking whether we are cross compiling... no
checking for suffix of executables...
checking for suffix of object files... o
checking whether we are using the GNU C++ compiler... yes
checking whether g++ accepts -g... yes
checking for gcc... gcc
checking whether we are using the GNU C compiler... yes
checking whether gcc accepts -g... yes
checking for gcc option to accept ISO C89... none needed
checking how to run the C preprocessor... gcc -E
checking for grep that handles long lines and -e... /usr/bin/grep
checking for egrep... /usr/bin/grep -E
checking for ANSI C header files... yes
checking for sys/types.h... yes
checking for sys/stat.h... yes
checking for stdlib.h... yes
checking for string.h... yes
checking for memory.h... yes
checking for strings.h... yes
checking for inttypes.h... yes
checking for stdint.h... yes
checking for unistd.h... yes
checking whether ld accepts -framework OpenGL... yes
configure: adding -Wl,-framework -Wl,OpenGL to OPENGL_LIBS
checking whether gluTessCallback is called with "(...)"... no
OPENGL_LIBS: -Wl,-framework -Wl,OpenGL
configure: creating ./config.status
config.status: creating config.h
bash$ autoheader && autoconf && ./configure --without-framework-
opengl
my output once again then is
checking whether ld accepts -framework OpenGL... yes
configure: Framework rejected by --without-framework-opengl
checking for GL/gl.h... no
checking for OpenGL/gl.h... yes
checking for GL/glu.h... no
checking for OpenGL/glu.h... yes
checking for glEnable in -lGL... yes
OPENGL_LIBS: -L/usr/X11R6/lib -lGL -lGLU
ie. the OpenGL libs from our X11 system are taken. If this works and
there is no other objection then I'll prepare the changeset for
Octave and Mac's framework OpenGL.
$ autoheader && autoconf && ./configure --without-framework-opengl
checking for g++... g++
checking for C++ compiler default output file name... a.out
checking whether the C++ compiler works... yes
checking whether we are cross compiling... no

Looks good!
