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

Is anyone familiar with the following error? I don't see it already on the
list.

I'm using current svn under Cygwin with GCC 3.4.4-3. Obviously this is a
constant that somehow got undefined. If I were to go in and give it a quick
fix via #define INFINITY (something), what would I use?
When building from the svn repository on Cygwin, I use the following:
CPPFLAGS="-DNOMINMAX -DINFINITY=HUGE_VAL" ./configure
--with-boost-include-dir=/usr/include/boost-1_33_1
INFINITY appears to be (inadvertently?) omitted from the Cygwin
include files. NOMINMAX works around a Microsoft incompatibility
with ANSI C++ (required when using libusb 0.1.12; see
http://www.gnuradio.org/trac/ticket/145).
