[FFmpeg-user] undefined reference to `_inflate'

[Kyle]

When trying to compile ffmpeg with rtmp I get this error:

i686-w64-mingw32-gcc 
-L/home/kyle/software/ffmpeg/external-libraries/win32/lib

You can see that -lz is included, so I'm not sure whats actually going 
wrong?

Here it is with -lz at the end:

Any ideas?
