Hi All,

I pulled the latest from develop and am getting errors building with
msys2. The build errors out on rtpmidi (errors pasted below). Seems
like a linking issue, but I haven't quite found what's the fix. (I'm
also travelling for the next few weeks and am intermittently looking
at Csound dev.)

Any help appreciated!
steven

Looks like you might be missing the winmm.dll (or whatever it is called), the windows MM library.

The flags had -lwinmm.  However, even worse, I deleted my
CMakeCache.txt and retried a build using ./build.sh and the build is a
mess now. I get linker problems for both fluidOpcodes and csound64
(the latter pasted below).  I feel like these were problems that were
solved a while ago but reintroduced.

Could someone else building with MSYS2 do a clean build and let me
know if you're also getting errors?

I tried that yesterday but it didn't have any effect. It doesn't matter at the moment anyways as I can't even get far enough to compile the portmidi driver.

I don't use a custom cmake file. I use a script. I just pull the repo,
build the packages, and then run this:

I don't use a custom cmake file either, not sure what you are
referring to. (Maybe you misread my note about the CMake cache file?
Deleting the cache file or deleting the csound-mingw64 folder will
ensure a clean build from scratch.)

Anyways, I had to go through git history to see that code was removed
and only "pthread" was looked for, when the order should have been
winpthread-1, then pthread, then pthreadGC2.  I've restored that and
am past the pthread link issues and back to the portmidi issues.

Okay, I've fixed it. It had to do with the ordering of
target_link_libraries. Having PORTMIDI_LIBRARY first got it to link.

I get close to a full build now, but python interface now fails:


In file included from C:/Python27/include/Python.h:8:0,
                 from
C:/msys64/home/stevenyi/work/csound/csound/mingw64/csound-mingw64/python_interfacePYTHON_wrap.cxx:182:
C:/Python27/include/pyconfig.h:285:15: error: 'std::_hypot' has not
been declared
 #define hypot _hypot

I've just disabled it and CsoundAC and have a complete build now. I'm
going to move on now as this has taken up too much time.
