try and follow this

create a opengl es form version.

copy libogg and libvorbis .h and .c files to inc and src.

set include path and exclude tune.c and psytune.c

compile.

run.

you can find that the app crash even without using any code libogg and libvorbis.

i think it may be conflict with some system code , it link with the code in libogg or libvorbis . so it is crash.

but i don’t know which function is conflict , can you check for it?

BTW, it can’t start at all,so it confuse me for a long time.
