I have also added LOCAL_LDLIBS := -llog -lGLESv1_CM in Android.mk file
I don’t know why such type of error is coming.
Can anybody please help me to solve this problem?
Answer determined in question comments above:
The compiler can’t find GLES/gl.h. If you’ve only added a linker directive, you probably need to tell the compiler where those headers are too.
