Re: [Discuss-gnuradio] [gnuradio 3.5.0] libgnuradio-core.so: undefined reference to `fftwf_free'

[klo uo]

Two things are missing, the linker command does not include the library
(i.e. -lfftw3f) and not the library path (-L/home/klonuo/.local/lib).
The latter is instead just appended to that last command which is wrong.

FFTW3F_LIBS should be something like this '-L$HOME/.local/lib -lfftw3f'

Ah, that should be the problem then. Thanks for spotting it, I thought just absolute path was needed.

I'm trying something else right now (Debian/Ubuntu issue with "/etc/ld.so.conf" as noted in gnuradio wiki) and it seem like it would build fine, as it's compiling almost half hour (libfftw error did not show) and report back shortly, for possible future reference to this problem

Cheers
