[Clfs-support] CLFS support

[Kevyn-Alexandre Paré]

The ldconfig in the make install in the 4.9 section is the problem:

ls /mnt/clfs/cross-tools/arm-linux-musleabihf/lib/ld-musl-armhf.so.1
/mnt/clfs/cross-tools/arm-linux-musleabihf/lib/ld-musl-armhf.so.1
clfs at knight:/mnt/clfs/sources/musl-0.9.14$ /sbin/ldconfig -n
/mnt/clfs/cross-tools/arm-linux-musleabihf/lib
/sbin/ldconfig.real:
/mnt/clfs/cross-tools/arm-linux-musleabihf/lib/libstdc++.so.6.0.17-gdb.py
is not an ELF file - it has the wrong magic bytes at the start.

clfs at knight:/mnt/clfs/sources/musl-0.9.14$ ls
/mnt/clfs/cross-tools/arm-linux-musleabihf/lib/ld-musl-armhf.so.1
ls: cannot access
/mnt/clfs/cross-tools/arm-linux-musleabihf/lib/ld-musl-armhf.so.1: No
such file or directory

So since the
ls -l /mnt/clfs/cross-tools/arm-linux-musleabihf/lib/ld-musl-armhf.so.1
lrwxrwxrwx 1 clfs clfs 12 Feb 10 19:54
/mnt/clfs/cross-tools/arm-linux-musleabihf/lib/ld-musl-armhf.so.1 ->
/lib/libc.so
clfs at knight:/mnt/clfs/sources/musl-0.9.14$ ls -al /lib/libc.so
ls: cannot access /lib/libc.so: No such file or directory

To solve the issue I just made a test by doing:
sudo touch /lib/libc.so
Then when ldconfig is called the  ld-musl-armhf.so.1 is not deleted.

His there a better way to fix that?

thx
