Just popping in

Hi

I'm getting the following errors while compiling GLES Demo sources(trianglecolour f.e):
/SDK/local/newlib/lib/libegl_wrap.so: undefined reference to `operator new[](unsigned int)'
/SDK/local/newlib/lib/libegl_wrap.so: undefined reference to `operator delete[](void*)'
/SDK/local/newlib/lib/libegl_wrap.so: undefined reference to `operator delete(void*)'
/SDK/local/newlib/lib/libegl_wrap.so: undefined reference to `__cxa_pure_virtual'
/SDK/local/newlib/lib/libegl_wrap.so: undefined reference to `__gxx_personality_sj0'
/SDK/local/newlib/lib/libegl_wrap.so: undefined reference to `vtable for __cxxabiv1::__vmi_class_type_info'
/SDK/local/newlib/lib/libegl_wrap.so: undefined reference to `vtable for __cxxabiv1::__class_type_info'
/SDK/local/newlib/lib/libegl_wrap.so: undefined reference to `ITimer'
/SDK/local/newlib/lib/libegl_wrap.so: undefined reference to `operator new(unsigned int)'
/SDK/local/newlib/lib/libegl_wrap.so: undefined reference to `vtable for __cxxabiv1::__si_class_type_info'

any idea what I might be missing? libegl wrap libraries and include files are installed, compiled demos are working fine...

thanks

Home away from home

Probabaly you trying to compile c++ example via gcc (but should use g++ instead) , or, if you still want to use gcc binary, you need to add at end -lstdc++

@kas1e

Yes, that's probably it :)
I didn't notice there is g++ in original makefile instead of gcc...
Anyway, I had to modify my makefile manually, codebench seems to be ignoring some changes that are needed

thanks :)

Not too shy to talk

@NoCache
hello, actually kas1e is absolutely right and you must use the same linkage as the makefiles provided in the demos, I advise to check the makefile create by codebench once initialize before continuing. soon a new update will be made with new examples to better help you. have a good day
