Hiii
I did following :
build% make
build% make test
gr-digital% gr-modtool makexml ofdm_chanestMMSE_vcvc
build% make install
everything seemed successful but WHEN opening GRC one block pop ups with :
" Cannot import gnuradio.
Is the python path environment variable set correctly?
All OS: PYTHONPATH
Is the library path environment variable set correctly?
Linux: LD_LIBRARY_PATH
Windows: PATH
MacOSX: DYLD_LIBRARY_PATH "
What happened ? Previously it was running... please help..
