Hi Arnaud - back on this bug from last April, I guess I just don't think
it's the job of mkinstalldirs to follow symlinks. It feels like too big
a change in behavior. I think the real bug here lies in whatever
created the broken symlink in the first place.

So I'm going to close this one. All the best,
Karl

Hi,

I encounter an issue while working with glibc with script scripts/mkinstalldirs. In scriptversion=2018-03-07.03; # UTC.

I had a symbolic link lib64->lib and the folder lib did not exist.

The glibc installing process is calling   ./scripts/mkinstalldirs [..]/lib64 which failed to mkdir -p it.

I made a working patch for my case, which need to be reworked as a loop (As I use the script with a single argument $@ and not a list of them).

Here is my solution:
