Hia! It's an upstream report of downstream build failure at https://github.com/NixOS/nixpkgs/pull/137502
There omxil
fails to build as:
ld: base/.libs/libomxbase.a(libomxbase_la-OMXComponentRMExt.o):(.bss+0x10): multiple definition of `listOfcomponentRegistered'; .libs/libomxil_bellagio_la-st_static_component_loader.o:(.bss+0x350): first defined here ld: base/.libs/libomxbase.a(libomxbase_la-OMXComponentRMExt.o):(.bss+0x18): multiple definition of `globalIndex'; .libs/libomxil_bellagio_la-st_static_component_loader.o:(.bss+0x358): first defined here collect2: error: ld returned 1 exit status
gcc-10 changed the default from -fcommon to fno-common: https://gcc.gnu.org/PR85678.
Attached the patch that seems to be enough to fix it.
