librfftw.so.2: cannot open shared object file

[Anonymous]

Hi,

Love X11basic and have used it for a few years to write software for my
home and to handle midifile conversion for my (vintage) musical
keyboard. Lately I have hit a problem. Having replaced my desktop and
upgraded to Linux Mint 18.1 XFCE version when I download either the rpm
or compile from new when I try to run X11basic I get "librfftw.so.2:
cannot open shared object file". My Laptop running Mint 17.1 XFCE works
fine and when I do a 'find' on my laptop there is no file librfftw.so.2.
Really confused.

Hi Neil,
librfftw.so usually comes with the packet fftw.
I hope that helps

Hello Markus,

Thanks for your work with X11-Basic; I tryed the .deb package this morning on a Linux Mint 18.1 Cinnamon and despite package manager told that every dependencies are satisfied I got the librfftw.so missing error. Should I install others packages?

Regards,
Alain

The package was made for Ubunut Linux. There, the librfft librar is includedin the libfftw package.

Hello Markus,
Thanks for the answer; so I suppose libfftw is a standard package from Ubuntu that was removed from Mint. I corrected my installation by

sudo apt install fftw2

and now I can play with X11-Basic ;))

Thanks.
