libGLES_CM.so is missing

[GLBasic]

as said, we're using OpenGL|ES 1.1 and the library seems missing on the Ubuntu image. Anything I can do?

[Breakthrough]

I'm trying to port an SDL OpenGL application to OpenGL-ES, and ran into the same problem. I made sure I installed the proper packages, but the linker couldn't find libGLES_CM.

So, puzzled, I searched for all files starting with "libGL", and actually found that the library was infact present - just with a slightly different name: libGLESv1_CM.

Thus, for OpenGL ES v1.x, you link with the flag -lGLESv1_CM, and for v2.x, you link with the flag -lGLESv2.

at least with the debian image everything was tucked away in /opt/vc

so /opt/vc/include has the headers and /opt/vc/lib has the libs

There is no GLES_CM. GLESv2 contains both GLES v1 and v2. Make sure you link with the hw accelerated libs (usually installed in /opt/vc/lib).

Then why not making a link by default from GLESv1_CM to GLESv2 ?
Many source code depends on this name so it would avoid to waste time on this issue...

[dom]

Does this:
cd /opt/vc/lib
sudo ln -s libGLESv2.so libGLES_CM.so

make building easier?

[Chips]

no, you're missing the v1
eg:

sudo ln -s libGLESv2.so libGLESv1_CM.so

[dom]

no, you're missing the v1
eg:

sudo ln -s libGLESv2.so libGLESv1_CM.so

Okay, so would doing:
sudo ln -s libGLESv2.so libGLESv1_CM.so

make building easier? I can probably add that to the git repo, so you cat that link as standard.

[Chips]

Yes, that would helps
