Hi,

When I build a minimal Csound version (using the build script from the
repo from Feb 27), it produce an error on startup regarding a missing
libwinpthread-1.dll. I suspect there might be a dynamic link to this
file somewwhere (introduced some time during the 4-5 weeks or so).

Is there any specific reason why this was introduced? I thought it
should all be static linking now?
Does it perhaps relate to this:

?

If I delete osd.dll from the plugins folder, I do not get the
libwinpthread error.
Where should I change a setting to try to compile osc.dll statically linked?

Thanks you for looking into it, Mike.
Are you able to find out what flags?

I think that in the link command you just put -static ahead of the libraries you want to link statically. You can mix this with -dynamic but obviously that is not what we need here.

Regards,
Mike

Hi
I tried modifying line 182 of CMakeLists.txt to
    make_plugin(osc OSC.c -static-libgcc -static)
also tried
    make_plugin(osc OSC.c -static)

But still get the libwinpthread error when running csound, if osc.dll
is present in the plugin dir

Sounds like liblo needs to be built statically. I think I've done this too in the past, but not with msys2. I can take a look but I would prefer if this was the default for the msys2 liblo package.

aha, that makes sense.
I just used the PKGBUILD in csound/mingw64/packages/liblo.
I had built it earlier, but had to do it again now as I cleaned out
the whole local copy of the repo to make sure I had a fresh build.
Perhaps the packages had been updated (the package in our repo, or the
liblo source?) That might explain why this behaves differently here
now than it did a month ago.

Interesting, I don't get that error here and I'm still using the package Steven provided me. But I will need to double check as I do have libpthread somewhere in my path. I can check tomorrow.
