Custom-installed libraries should be installed under /usr/local (so either /usr/local/lib of /usr/local/lib64). After installation you need to update the linker cache by running ldconfig (or 'ldconfig -v' to see what's going on). This needs to be done as root. To check which library your application actually does link to run: ldd /usr/local/bin/mycoolapp | grep fluidsynth HTH Ralf Mattes > > On 08/09/2017 22:46, Tom M. wrote: > > I guess that you have libfluidsynth.so installed somewhere in > > /usr/lib/ and this one was compiled without alsa support.
