avidemux-core-2.7.4-r1::mv fails to build with LTO

Open fatalhalt opened this issue 5 years ago • 3 comments

avidemux-core fails to build with LTO. I had to include -fno-lto in the CFLAGS to disable LTO. Somebody please add avidemux-core workarounds to the gentooLTO project, thanks.

It says recompile with -fPIC multiple times - have you tried that instead of disabling lto?

Hello Jannik2099, unfortunately -fPIC didn't help:
