Re: [Discuss-gnuradio] Nothing known about namespace 'pmt'

Hi Bastian,

Thanks for your reply.

In fact what you suggested was exactly the case. I had an old gnuradio installation before having an ubuntu upgrade. So by manually deleting the old files problem was solved.

Also all the required libs seem to be found during cmake including GRUEL
and "/usr/local/include/gruel/swig/pmt_swig.i", where namespace 'pmt' is
defined, exists.
Also the package was installed on an identical machine with Ubuntu 12.04
just fine!

I never encountered that problem... the only thing that would come to my mind is that maybe you have multiple installations on the system (like one from the package manager and one built from source) and thus files from another installation are used?
Or you could try to delete CMakeCache.txt from the build directory. If you then type make again you see where it found the gruel library.

Best,
Bastian
