pthread dependency in webp-leptonica #34

Closed GoogleCodeExporter closed 9 years ago

Can you remove the dependency on pthreads?

This is the link error
cd /c/src/webp/libwebp

The references are found here:
src\Makefile:VPX_LIBS = -lvpx -lpthread
src\Makefile.am:VPX_LIBS = -lvpx -lpthread
src\Makefile.in:VPX_LIBS = -lvpx -lpthread

Removing those references, webp builds ok on msys

Now in the new reference implementations for WebP encoder & decoder, 'pthread' 
dependency is not required:
