Conflicts between extension function decls (I could just be dumb)

Thanks, I will take a look. I assume you're using it for the D programming language? Are you using the latest version I fixed a bug like that in the last commit.

Can you give me some more information, I tried to reproduce this, but everything I try seems to compile, e.g.:

─[dav1d@archbox][~/workspaces/d/glad]╼ python2 main.py --out-path=./build --generator=d                                                                                          1 ↵  ✭master 
Using local spec: gl.xml
Generating gl bindings...
─[dav1d@archbox][~/workspaces/d/glad]╼ dmd -Ibuild build/glad/gl/* -L-ldl                                                                                                             ✭master 
/usr/lib/gcc/x86_64-unknown-linux-gnu/4.9.0/../../../../lib/crt1.o: In function `_start':
(.text+0x20): undefined reference to `main'
collect2: Fehler: ld gab 1 als Ende-Status zurück
--- errorlevel 1

The last error message means, there is simply no main function, linking failed (expected), but compilation succeeded.

Can you give me the command you use to compile your code and the command which you used to generate the loader?

Thanks

Ah, sorry about that.

I'm using the C binding actually, but with one important distinction: I'm compiling the resulting .c file as C++ instead of C. Apparently C doesn't care that there are multiple definitions of these things, but C++ is more strict.

The loader generator command:

python main.py --profile=compatibility --out-path=testloader --api="gl=" --generator=c --spec=gl

Then I rename testloader/src/glad.c to glad.cpp, and compile:

gcc testloader/src/glad.cpp -I./testloader/include

The three last extensions are also written against plain OpenGL, so there's nothing wrong about them getting loaded:
https://www.opengl.org/registry/specs/EXT/geometry_shader4.txt
https://www.opengl.org/registry/specs/EXT/separate_shader_objects.txt
https://www.opengl.org/registry/specs/EXT/direct_state_access.txt

Concerning the compilation error you encounter, this is not valid C++ code. (3.2 One definition rule)
However, this is valid C code since those are all tentative definitions. (6.9.2 External object definitions)
Glad supplies a C binding that requires a C compiler. I see no bug.

Why would you want to compile it with a C++ compiler?

[Dav1dde]

With latest commit, C++ should be supported. My small tests run through and @pyalot uses it in a bigger C++ project.

Ok now it is really fixed, thanks everyone!
