Odi's astoundingly incomplete notes
New entries | CodeGentoo enables PIE
Gentoo has new profiles that require you to "recompile everything". That is technically not really necessary. Only static libraries really need recompiling.
Here is why:
A static library is just an archive of .o files (similar to tar), nothing more, and linking against a static library is roughly the same as just adding more .o files to the linker line. You can also link a static library into a shared library - the code in the static library is then just copied into the shared library (but the code then must be compiled with -fPIC, as with all other code that is used in shared libraries).
You can find static libs like so:

equery b $(find /usr/lib/ /lib/ -name *.a) | awk '{ print $1; }' | sort | uniq
Typically this yields packages like elfutils, libbsd, nss, iproute2, keyutils, texinfo, flex, db, numactl.Add comment
