[FFmpeg-devel] [cygwin] how to compile with pure cygwin (not with no-cygwin)?

[Frédéric Bron]

I have many troubles to compile with cygwin. I want a cygwin version of
ffmpeg because it is called by a bash script (diascope) that does not work
properly with the pure win32 version. However, I am not able to compile
ffmpeg.

I have tried to add the definition of llrint in libavcodec/i386/mathops.h as
suggested in a post:
#ifndef llrint
inline long long int llrint (double x)
{
    long long int llrintres;
    asm
    ("fistpll %0"
    : "=m" (llrintres) : "t" (x) : "st");
    return llrintres;
}
#endif

This works fine but then the next trouble is with libavformat/os_support and
gethostname. Here I tried some suggestions in a post but could not succeed.

Here is my configure command:

../configure --enable-static --disable-shared
--prefix=/cygdrive/c/Softs/ffmpeg --disable-vhook --disable-ffserver
--disable-debug --disable-network

Here is the error I get:

Can somebody help or  make a tar.gz suitable for cygwin?
