[Help] darktable x86_64 compilation error #833

Closed knyipab closed 8 months ago

knyipab commented 8 months ago

I am adding a new package darktable (https://www.darktable.org/). I managed to get aarch64 compilation successful but x86_64 does not (FYI 32-bit are not supported by official source), with strange linker errors error: relocation refers to a symbol in a discarded section. I am not very familiar with compilation and really grateful for help.

The code is avilabale at the darktable branch: https://github.com/knyipab/tur/blob/darktable/tur/darktable/build.sh.

The build log is available at https://github.com/knyipab/tur/actions/runs/7945273863/job/21691739193#step:7:7049, with excerpt below:

Thanks for any help!
