[Scummvm-devel] Png compilation error

[Федор]

You was right. Compiler find png.h in system include path but used scummvm's one. I have changeg ifdef guards and succesfully compile scummvm_base.lib.
#ifdef USE_PNG
# ifdef __SYMBIAN32__
# include <png/png.h>
# else
# include <png.h>
# endif // __SYMBIAN32__
#endif // USE_PNG

But when I try to build scummvm.exe I got these errors:
Creation Time Description Resource Path Location Type

scummvm_base.lib(png.o): In function `Graphics::PNGDecoder::loadStream(Common::SeekableReadStream&)':
