While replying to Frans on -support re his inability to build
glibc-2.33, I glanced at the binutils bugs
https://www.mail-archive.com/bug-binutils@gnu.org/ and said that
2.36 might be buggy. At that time I hadn't read all the links
gurgle found for me. One of them is
https://www.linuxquestions.org/questions/linux-from-scratch-13/binutils-2-36-strip-4175689760/
which looks *really* annoying.
I took a look at the above link, but I cannot reproduce the problem with
LFS instructions. In my test build in /mnt/lfs/lib I have:
[ /mnt/lfs/lib ]$ ll libc*

[ /mnt/lfs/lib ]$ file libc-2.33.so
libc-2.33.so: ELF 64-bit LSB shared object, x86-64, version 1
(GNU/Linux), dynamically linked, interpreter /lib/ld-linux-x86-64.so.2,
for GNU/Linux 3.2.0, stripped
[ /mnt/lfs/lib ]$ file libcap.so.2.47
libcap.so.2.47: ELF 64-bit LSB shared object, x86-64, version 1 (SYSV),
dynamically linked, stripped
So the book does what we want. On the other hand, we do not do an
unconditional strip on anything. We start with find /lib /usr/lib -type
f -name \*.so* ... so that would skip symlinks.
We use the same structure in BLFS Section "Notes on Building Software".
On the other hand, doing an explicit strip on a symlink does replace the
symlink with the stripped version of the link's resolved file.
I can confirm that running strip against a symlink on a system with
binutils-2,25 does not affect the symlink.
