# Note re libc_cv_rtlddir, libc_cv_slibdir: this is required for AArch64

# However, running it like this has caused
# glibc to fail once during upgradepkg.  Upon investigation I found the symlink
# was missing.  This mitigates that risk.
# Note however that we include a symlink instead for compatability with 3rd party
# apps that target an OS where the linker lives in /lib.

  # First do the new libxcrypt links (a little bit differently):
  for cryptlib in libcrypt.so.* ; do
    CRYPTSO=$(echo $cryptlib | cut -f 3 -d .)
    mv -fv $cryptlib libcrypt${CRYPTSO}-${VERSION}.so

  # This one is a special case. We don't want an $ARCH embedded in the
  # filename. It prevents using the same install scripts on all $ARCH
  # and does no good since we'll never have multiple $ARCH libraries
  # installed in the same directory anyway. So give it the previous name
  # format:
  mv -fv ld-linux*-${VERSION}.so ld-${VERSION}.so
)

# Add a compatability symlink for 3rd party packages
# Where they have the linker in /lib as opposed to /lib64:
[ "${SLKPORTARCH}" = "aarch64" ] && {
   mkdir -vpm755 lib
   pushd lib
   # Refer to the symlink to avoid any version number issues during upgrades
   # (should the /lib/ld-linux-aarch64.so.1 be taken in preference to /lib64 for
   # any reason):
   ln -vfs ../lib64/$ARMLDLINUXVER .
   popd ;}

# Build the package:
makepkg -l y -c n $PKGSTORE/l/glibc-$VERSION-$PKGARCH-$BUILD.txz

# Done!
