From: "Luis R. Rodriguez" <mcg...@suse.com> With binutils 2.25.0 libgmp is not found. When building studom's we build our own libgmp for each minios. On x86-64 all libraries are put on the directory:
stubdom/cross-root-x86_64/x86_64-xen-elf/lib/ The exception is libgmp, it gets tosse don lib64. It doesn't seem the latest linker might amend lib64 as a default search path when using -nostdlib -- I cannot confirm from binutils code changes that's the case yet, but at least through the observed behaviour that seems to be the case. Be explicit and peg the lib64 directory as part of the search path as well when on x86-64. This fixes the following final linker error: ld -r -d -nostdlib -L/sda3/home/mcgrof/devel/xen/stubdom/cross-root-x86_64/x86_64-xen-elf/lib -m elf_x86_64 -\( /sda3/home/mcgrof/devel/xen/stubdom/vtpm/vtpm.a -T app.lds -\) -ltpm -ltpm_crypto -lgmp -lpolarssl --undefined main -o /sda3/home/mcgrof/devel/xen/stubdom/mini-os-x86_64-vtpm/mini-os_app.o ld: cannot find -lgmp Signed-off-by: Luis R.
