[Discuss-gnuradio] block library not visible in grc

2013-05-07 Thread Martin Luessi
Hi, I'm using gnuradio on Gentoo Linux and for some reason the block library is no longer visible in GRC. The strange thing is that it was working a few months ago, but in the meanwhile I have updated my system and it no longer works. Possible a dependency update may be causing the problem but I

Hi, Michael, I try to install GNU Radio 3.6.4 on MacOSX 10.8.2 with MacPorts 2.1.3 by the following commands: $ sudo port install gnuradio +full configure.compiler=llvm-gcc-4.2 During the installation, I have to port -f activate qwt to proceed to install GNU Radio 3.6.4. This seems to be fine
