I misunderstood your problem -- I don't know about doing
cross-compilation with CMake. I would suggest that if you can
cross-compile ANY application for the targets you want, you could just
add the PortMidi source files to the other sources in the application.
PortMidi is not large, so (in my opinion) there are at best minor
advantages to dynamic linking or separate compilation.

Hi Roger,
Unfortunately I've tried for an hour or two to get cmake to spit out a
cross-compile Makefile and I failed miserably. First of all, I had to
remove every reference to the Java parts of the CMake configuration.
Then, when I tried the following:
ccmake -G "Unix Makefiles" -D CMAKE_C_COMPILER=i586-mingw32msvc-gcc -D
CMAKE_CXX_COMPILER=i586-mingw32msvc-g++ CMAKE_AR=i586-mingw32msvc-ar CMAKE_OBJDUMP=i586-mingw32msvc-objdump CMAKE_OBJCOPY=i586-mingw32msvc-objcopy CMAKE_NM=i586-mingw32msvc-nm
.
It produced a Makefile which was for building on Linux (included files
from pm_linux), not Windows. After reading through the various CMake
files, I'm worried that cross-compilation isn't possible. Has anyone
done it? For what I'm working on I'm going to need to cross-compile
from x86_64 Linux to: Windows x86/x86_64 and OSX 10.4
powerpc/powerpc64/x86/x86_64. With an autotools/autoconf setup this
is pretty straightforward, but I'm very inexperienced with cmake --
any advice would be much appreciated.
Best regards,
RJ

Now that PortMidi uses CMake, I believe you can create a fresh new
Makefile with CMake. That should work. -Roger

Hi all,
I'm trying to produce a cross-compiled build of portmidi for
win32 using the mingw32msvc toolchain availble in Debian/Ubuntu.
Could anyone who has done this successfully give me some
pointers? I'm using this Makefile I found here:
http://lists.create.ucsb.edu/pipermail/media_api/2005-June/000386.html but
I don't believe that is correctly prepared for the latest SVN or
for cross-compiling. It references a non-existent C file:
pmdll.c. After removing that reference it built fine, but after
linking with my binary (Mixxx http://mixxx.org
<http://mixxx.org/>) Windows (7) fails to recognize the DLL as valid.
Thanks,
RJ Ryan
