[Discuss-gnuradio] Problems building GnurRadio under Cygwin

[radio4pm]

I am attempting to build GnuRadio under Cygwin to work with a development board 
and am having mixed results.  I followed the instructions to build under Cygwin 
and generally it went fine.  Then I attempted to compile the block for the 
interface to the development board.  This was having trouble finding the 
gnuradio-core.  I then ran ./bootstrap to get the libraries set up properly for 
the block .  This again failed initially with the error related to aclocal.m4  
Following, guidance from other posts, I deleted this after the ./bootstrap and 
then ran ./configure and make.  make failed with a number of unresolved 
environment variables relating to ..._CXX. 

As a result, back to the drawing board, with the block installed in the 
gnuradio directory with the others, I attempted ./bootstrap to rebuild the 
makefiles and rebuild gnuradio.  It appears as I have now corrupted the 
original version in that it will no longer build as it cannot use/compile 
Python.h - configure follows below.  Any suggestions as to how to get gnuradio 
build and have the additional block actually find the files would be 
appreciated. 

Thanks,
