I'm trying to compile ruby-audio on a Raspberry Pi running Rasbian, but compilation fails. Here is the error (full log below):
compiling ra_sound.c
ra_sound.c: In function ‘ra_sound_init’:
ra_sound.c:155:5: error: format not a string literal and no format arguments [-Werror=format-security]
Apparently format-security compiler flag is breaking the build. I have tried to compile with -Wno-format-security, but still the build fails with the same error.
Any idea how to fix this?
