Building SDL-1.2.5 source tarball so I can use new gcc 3.2 compiler from
cygwin (I got some conflicts with the binary distro so I’m compiling the
lib myself).
configure, make, make install “works”, but…
When I build the tests, the testgl.exe outputs that OpenGL is not
supported on this system, I have opengl, what do I do?
Searching google, I found a libsdl.org page that has some info:
I downloaded the directx-devel.tar.gz and opengl-devel.tar.gz and
installed them into /usr per the instructions there.
./configure, make, make install appears to work
great, no errors (although I never see any OpenGL test on the configure
output, so I don’t know if this passed or not - it did find directx ok
though, and there was one line that just had a ‘:’ on it.)
looking at the configure.in, it is testing a program that includes glx.h,
but I don’t have glx.h on my system.
Is this documented? Anyone getting SDL-1.2.5 compiling with latest
cygwin (gcc compiler), and OpenGL support? Point me to docs, faq, or
something! 
(a readme in the source dir would be nice… you have all
the weird OSs, what about cygwin/win32?)
thanks
More info…
Here is what the compile line looks like when I build SDL:
gcc -DPACKAGE_NAME="" -DPACKAGE_TARNAME="" -DPACKAGE_VERSION=""
-DPACKAGE_STRING="" -DPACKAGE_BUGREPORT="" -DPACKAGE=“SDL”
-DVERSION=“1.2.6” -DHAVE_ALLOCA_H=1 -DHAVE_ALLOCA=1 -I.
-I…/…/…/…/src/video/dummy -g -O2 -Wall -DENABLE_DUMMYVIDEO

Is it the DUMMY_VIDEO param? Don’t I want video support if I’m using
opengl grahpics? maybe it means something else…
Anyway, hopefully that helps. Here is a little more info:

make 3.79.1

opengl headers)On Fri, 7 Feb 2003, Kevin Meinert wrote:

Hi,
WORKAROUND:
At the top of testgl.c, there is a
#ifdef HAVE_OPENGL statement. Before that, #define HAVE_OPENGL
and recompile. Hopefully it’ll work.
On the other hand, it may spit out a handful of errors about
conflicts in gl.h and SDL_OpenGL.h. Comment out the offending
lines in SDL_OpenGL.h and try compiling again.

You plan things that you do not even attempt because of your extreme caution.

looks like the reason that the test/configure is failing on opengl is this
(from config.log) PFNGLCOLORSUBTABLEEXTPROC symbol:
configure:4598: checking for OpenGL support

I also get this when I force a #define HAVE_OPENGL in testgl.c
thanks for the info,

Hi,
WORKAROUND:
At the top of testgl.c, there is a
#ifdef HAVE_OPENGL statement. Before that, #define HAVE_OPENGL
and recompile. Hopefully it’ll work.
On the other hand, it may spit out a handful of errors about
conflicts in gl.h and SDL_OpenGL.h. Comment out the offending
lines in SDL_OpenGL.h and try compiling again.
hth,

configure, make, make install “works”, but…
When I build the tests, the testgl.exe outputs that OpenGL is not
supported on this system, I have opengl, what do I do?

You plan things that you do not even attempt because of your extreme caution.

cool, that worked. I had link errors, but that was because I forgot to
rerun configure. after doing that, it added the appropriate libs to the
link line…
The fix to get it to autodetect opengl on my system was to comment out the
following line:
typedef void (APIENTRY * PFNGLCOLORSUBTABLEEXTPROC) (GLenum target,
GLsizei start, GLsizei count, GLenum format, GLenum type, const GLvoid
*data);
… since it was already defined in cygwin’s GL header.
NOTE: the sdl gl headers I installed appear not to be read, since they’re
installed in /usr/include/w32api/GL… once I copied those over to
/usr/include/GL, this also fixes the problem…

looks like the reason that the test/configure is failing on opengl is this

I also get this when I force a #define HAVE_OPENGL in testgl.c
thanks for the info,
