Hi,
I'm trying to build arm-elf-gcc --sysroot and my target does not have
a file system etc.
gcc building seems to enforce building of libgcov.a.
- Why is this enforced? I think libgcov is for converage
analyzing with gcov and has high requirements (such as needing
a file system).
- How can I disable building of libgcov.a?
I used a hack in libgcc/Makefile.in, see at the end of the
mail. How do I do this better?
