I think that helps clarify their intended use, I am trying to create a
slightly different structure for my cross compiler which is why I am
having issues.
For example I was building/installing with
PREFIX=<root-location> (i.e. something like /path/uclibc-root)
MULTILIB_DIR=mips64r2/64/el
DEVEL_PREFIX=/
I am trying to build a uclibc sysroot setup that mimics the glibc one I
have where there is a single <sysroot>/usr/include for the headers but
then multiple libc.a files in (for example) <sysroot>/usr/lib/libc.a,
<sysroot>/mips64r2/usr/lib/libc.a, or
<sysroot>/mips64r2/64/el/usr/lib/libc.a.
One thing I have just noticed is that this doesn't work because
usr/include contains uClibc_config.h which is different based on
what options you used to build uclibc (big or little endian; soft or
hard float; etc). All the other header files appear to be identical.
