[Discuss-gnuradio] SVN Compile Error Under Cygwin: Omnithread Stuff

[Reid N Kleckner]

So, that advice fixed that problem.  Now I have a problem similar to the one
documented here: http://www.gnuradio.org/trac/ticket/138  I applied the patch
listed there, but my error has not gone away:

/usr/src/gnuradio/gnuradio-core/src/lib/swig/gnuradio_swig_py_runtime.cc:(.text+
0x325be): undefined reference to `omni_thread::init_t::init_t()'
/usr/src/gnuradio/gnuradio-core/src/lib/swig/gnuradio_swig_py_runtime.cc:(.text+
0x325dc): undefined reference to `omni_thread::init_t::~init_t()'

Is there a similar fix to make it link/include/magic omnithread before 
building
the rest of the code?

Thanks,
Reid
