/tmp/go-build089296038/astyle/_obj/cpplib.cpp.o: In function `codeFormat ':
/home/google/0/src/astyle/cpplib.cpp: 99: undefined reference to `AStyleMain '
collect2: error: ld returned 1 exit status
But AStyleMain is declared, it is through cpplib.cpp contains astyle_main.h, then
through astyle_main.h will contain astyle.h
And astyle.h stated the following:
extern "C" EXPORT char * STDCALL AStyleMain (const char *, const char *,
fpError, fpAlloc);
When I'm alone through the gcc compiler, compiling is ok
