Hi, I'm currently trying to compile a .so file. I start ndk-build and each individual file seems to compile just fine, but at the end I'm faced with a long list of undefined reference errors.

It seems as if a lot of the parts of the standard library just aren't being found - any possible solutions?

Error message (shortened):

[armeabi] Compile++ thumb: main <= Mixer.cc

[armeabi] Compile++ thumb: main <= Music.cc

[armeabi] Compile++ thumb: main <= SDLMixer.cc

[armeabi] SharedLibrary : libmain.so
