Description Alexey Korepanov 2024-11-24 12:31:57 UTC

I had no issues with media-gfx/prusaslicer-2.8.1 and gcc-13.
But I cannot build media-gfx/prusaslicer-2.8.1-r1 with gcc-14, the error is

/usr/lib/gcc/x86_64-pc-linux-gnu/14/../../../../x86_64-pc-linux-gnu/bin/ld: /usr/lib64/libqhullcpp.a(Qhull.cpp.o): plugin needed to handle lto object

...


I tried it with lto disabled, but the error is the same

Reproducible: Always

As a workaround, building both qhull and prusaslicer without lto worked
