[FFmpeg-user] user32.lib missing in link call

[Bernhard Döbler]

Hi,

I call

$ ./configure \
--toolchain=msvc --arch=x86 \
--host-cc=gcc \
--host-ld=gcc \
--prefix=/deps \
--disable-ffplay \
--disable-ffserver \

--enable-encoder=flac,mjpeg,png,pcm_s16le,pcm_s16be,pcm_u16le,pcm_u16be,pcm_s8,pcm_u8,pcm_mulaw,pcm_alaw,pcm_s32le,pcm_s32be,pcm_u32le,pcm_u32be,pcm_s24le,pcm_s24be,pcm_u24le,pcm_u24be,pcm_s24daud,pcm_f32be,pcm_f32le,pcm_f64be,pcm_f64le
$ make

and finally recieve:

Something configured obviously needs GetShellWindow but user32.lib is 
not added to the list of libraries ffmpeg_g.exe is linked against.

I thus added
--extra-libs='user32.lib'
to my configure call.
