[pulseaudio-discuss] Having a bit of trouble compiling on Cygwin

[Vadim Troshchinskiy]

Hello,

I'm attempting to build the latest source on Cygwin and having a bit of 
trouble:

After a few minor fixes to get things to compile, it builds, but this happens:

$ src/pulseaudio.exe -F src/default.pa
W: [(null)] caps.c: Normally all extra capabilities would be dropped now, but 
that's impossible because PulseAudio was built without capabilities support.
N: [(null)] daemon-conf.c: Detected that we are run from the build tree, 
fixing search path.
E: [(null)] ltdl-bind-now.c: Failed to open module libFLAC.dll: No such file 
or directory
E: [(null)] ltdl-bind-now.c: Failed to open module libgsm.dll: No such file or 
directory
E: [(null)] ltdl-bind-now.c: Failed to open module libFLAC.dll: No such file 
or directory
E: [(null)] ltdl-bind-now.c: Failed to open module libgsm.dll: No such file or 
directory

It seems like it should be looking for cyggsm.dll and so on. I have tried to 
work around that by symlinking files, but then this happens:

$ src/pulseaudio.exe -F src/default.pa
W: [(null)] caps.c: Normally all extra capabilities would be dropped now, but 
that's impossible because PulseAudio was built without capabilities support.
N: [(null)] daemon-conf.c: Detected that we are run from the build tree, 
fixing search path.
E: [(null)] ltdl-bind-now.c: Failed to open module libwinmm.dll: No such file 
or directory

There is no libwinmm.dll on Cygwin, only a static library, /usr/lib/w32api/
libwinmm.a.

Attempting to force static linking didn't work:

And at this point I got stuck. I can see there are Windows binaries, so there 
has to be a way to get things to work properly. Some help would be greatly 
appreciated.

Thanks in advance.
