Errors building coprthr on cygwin

[stevechk]

I'm trying to get the library to compile under cygwin. I built the dependent libraries from source, and have all the lib*.a files (though it looks like the .so gets mangled by cygwin). I made a couple of small tweaks to get most of it to compile, but getting stuck with the error below. Any ideas?

$ make
make -C src/libocl
make[1]: Entering directory '/home/steve/coprthr/src/libocl'
make[1]: Nothing to be done for 'all'.
make[1]: Leaving directory '/home/steve/coprthr/src/libocl'
make -C src/libclrpc
make[1]: Entering directory '/home/steve/coprthr/src/libclrpc'
cc -g -O2 -g -O2 -fPIC -o clrpcd clrpcd.o clrpc.gen.o   -lpthread -ldl -lrt  -L/usr/local/lib -levent -levent_pthreads -levent_pthreads -L/usr/local/lib -lconfig \
        -L../libocl -locl -L. -lclrpc
../libocl/libocl.a(libocl.o): In function `read_oclconf_info':
/home/steve/coprthr/src/libocl/libocl.c:654: undefined reference to `config_init'
/home/steve/coprthr/src/libocl/libocl.c:654:(.text+0x7f4): relocation truncated to fit: R_X86_64_PC32 against undefined symbol `config_init'
...

Looks like libocl.a gets built fine, but for some reason the link with libconfig is failing?

Also, are you interested in providing cygwin compatibility in general? I'd be happy to send you a pull request for any changes when I'm done.

thanks Steve

Looks like the issue is due to library ordering. The following appears to compile fine:

cc -g -O2 -g -O2 -fPIC -o clrpcd clrpcd.o clrpc.gen.o -L../libocl -L/usr/local/lib -L. -locl -lclrpc -lpthread -ldl -lrt -levent -levent_pthreads -levent_pthreads -lconfig

Still working through the rest of the changes needed.

We have not tested on cygwin.

If you report whatever else you find, we will update the 1.6 branch and include in the next release.
