Re: [Discuss-gnuradio] problem building gr-howto-write-a-block-cmake

[Achilleas Anastasopoulos]

I installed swig 1.3.40 and i have the same problem!!!!!!!!!!!!!!!!!

is there any other way i can check if the required PyhtonLibs
are indeed available in my system?
The fact that gnuradio trunk builds without a problem makes me go crazy...

thanks
Achilleas
