I configured gr 3.6.4 to install in my prefix /opt/usr, and I caught the installer putting the conf stuff in /usr/local anyways. I wasnt sure if this was the intention, since there was some ramblings about FHS, and /etc stuff cmake ~/src/gnuradio/ -DCMAKE\_BUILD\_TYPE=Release -DCMAKE\_INSTALL\_PREFIX=/opt/usr/gr The end of the make install including error: > CMake Error at gnuradio-core/cmake\_install.cmake:38 (FILE): > file cannot create directory: /usr/local/etc/gnuradio/conf.d.

Josh, you need to set SYSCONFDIR separately from CMAKE\_INSTALL\_PREFIX.

Most likely, it was already set somewhere else and you CMakeCache.txt file saw that and used the pre-set version. You’d have to explicitly set that variable now (or wipe away your cache file and reconfigure). Tom
