Gabriel,
I just made a patch that does the same kind of thing. Well, it does
that and a few other things. I’d suggest that it might be a better
fix. I’ve resolved the conflict and attached the result. Lemme know
what you think.
Works on Ubuntu and doesn’t break anything new on my Mac. I say
doesn’t break anything new because a few things are quite broken on
the mac in the past 24-36 hours.

This should fix the GL and GLES problems in tests:

One caveat though…if you are using Linux with Nvidia binaries testgles
won’t work out of the box…
The compile command for it will be something like:
gcc -o testgles …/testgles.c -g -O2 -D_REENTRANT -I/usr/local/include/SDL2
-DHAVE_OPENGLES -DHAVE_OPENGL -Wl,-rpath,/usr/local/lib -L/usr/local/lib
-lSDL2 -lpthread -lSDL2_test -lGLESv1_CM -lm
However, Nvidia is not providing libGLESv1_CM.so, Mesa is, and they are
incompatible…so while it will appear that everything is fine, what you
actually want for this to work is something like:
gcc -o testgles …/testgles.c -g -O2 -D_REENTRANT -I/usr/local/include/SDL2
-DHAVE_OPENGLES -DHAVE_OPENGL -Wl,-rpath,/usr/local/lib -L/usr/local/lib
-lSDL2 -lpthread -lSDL2_test -L/usr/lib/nvidia-313-updates -lGL -lm
And before you come complaining about this, I think Linus Torvalds said it
best…(NSFW)

adding a couple of debug echo statements at this point to the standard
configure.in to see what configure thinks those values are? If they’re
not what they should be, that’d be useful to know.
I have added at the end of if test x$have_x, and just before
dnl Check for OpenGL,
echo “$ac_x_includes and $ac_x_libraries”, values are empty, so the
AC_PATH_X doesn’t work for me ?
More variables to test in about the same spot:
$have_x
$x_includes
$x_libraries
I notice that the main configure.in uses those, not $ac_x_includes ?
Otherwise, let’s continue:
Default to we don’t have OpenGL
If we can compile #include “SDL_opengl.h”, we DO have OpenGL
for me, it seem that the :
AC_TRY_COMPILE([
#include “SDL_opengl.h”
],[
],[
have_opengl=yes
])
doesn’t work
in fact at last I have opengl/opengles = no
maybe because the AC_PATH_X path before.
Possibly. The no input files error is bugging me. Usually you get that
when gcc is misconfigured or not installed in the right spot on mingw or
something. Well, one bug at a time.
Let’s leave this here in case someone is looking at this message without
context and wants to try and interpret it:
Here what I have in config.log :

For the path, I don’t modified something, it was installed here at the
package install step.
Sorry if I forgive to give more informations, I’am not a specialist
with autotools:)
Thank you for your help and time
I’m happy to help. I’d be a lot happier if I actually WAS some help?
It’s been a freakin’ decade since I dealt with autocrap. I really did not
miss it.
But it needs fixing, and fixing it is relevant to my interests, which
involve nice, crunchy pi?
Joseph
