Segmentation Fault on Android when using OpenGL ES 3 functions

Question

I'm trying to create an application using the NDK. I'm using ndk-build because I'm also using some external libraries which don't yet support CMake. This is the relevant line in Android.mk:

LOCAL_LDLIBS := -lEGL -lGLESv3

Everything builds (compiles and links) just fine, but when I try to use a function from OpenGL ES 3.0+ (like glGenVertexArrays), I get a segmentation fault.

When I look into the debugger, though, I see this:

So, it is linking against libGLESv1_CM.so for reasons I don't understand.

Also, on my header files, I have #include <GLES3/gl3.h> and my device supports OpenGL ES 3.2 (I also saw the libGLESv3.so file on /system/lib/).

What could I be missing?

Answer 1

The external library I was using included the source gl3stub.c, presumably for supporting older OpenGL ES specifications. This was nullifying the pointers to newer APIs. Removing this source and recompiling the external library solved the issue.
