How to split large .a static library?

Question

Is there a possibility to split large .a files into multiple smaller ones?

I'm currently having an issue with a .a file being multiple GiB large and GCC raises an error even with the flag -mcmodel=medium.

Use binutils tool "ar":

ar -x libbig.a

for extracting the objects from the archive and

ar -r libsmall.a obj1.o obj2.o obj3.o

for creating a new archive.
