That is one of the things I havn't figured yet ... libgcc is basically a collection of object files, and the linker should cherry-pick those which it needs (for example add the _divdi3.o object to resolve the __divdi3 symbol) and ignore everything else. The "ignore everything else" part seems to not work though: > > /usr/bin/ld: /usr/lib/gcc/x86_64-redhat-linux/11/libgcc.a(_absvsi2.o): in > > function `__absvdi2': > > (.text+0x18): undefined reference to `abort' Nothing in edk2 needs __absvdi2. Nevertheless the linker looks at _absvsi2.o and tries to resolve the symbols used. Unpacking libgcc, cherry-picking the object files actually needed, then packing the picked object files into a library and use that works. But IMHO that is something the linker should be able to figure on its own. take care, Gerd -=-=-=-=-=-=-=-=-=-=-=- Groups.io Links: You receive all messages sent to this group.
