Linker error

GNU Radio
1

Hi GNURadio-Community,

I tried to install GNU-Radio 3.7 on Ubuntu 13.04. After getting all the
dependencies with the instructions from
http://gnuradio.org/redmine/projects/gnuradio/wiki/UbuntuInstall “cmake”
worked,
but when I tried “make” I got an error message:

I attached the cmake-messages as a .txt-file. Do you know what is the
reason for the error and how it can be solved?

Thank you very much for your help!

Cheers,
Sebastian

You cant be the only one who has compiled 3.7 w/ 13.04. Anyone else have
success w/ 13.04. Unfortunately I have not upgraded my system yet :slight_smile:

If 13.04 gcc is really going to complain like this: recompile with -fPIC
, then FWIW, the CMakeLists.txt could look like this to fix the issue:
