Hi,
Uh, huh.

I.e. a symlink to the source directory, not a symlink inside the source
directory.

Argh, this is missing spaces around the '=', leading to the branch always
being entered.
What I don't understand is how that possibly could affect the prep_buildtree
step, that happens earlier.
Hm.
Uh, I don't think it does? Afaict this failure is entirely unrelated to 'touch
meson.build'? From what I can tell the problem is that config/prep_buildtree
is invoked with the symlinked path, and that that doesn't seem to work:
bash -x /home/andres/src/postgresql-via-symlink/config/prep_buildtree /home/andres/src/postgresql-via-symlink .
++ basename /home/andres/src/postgresql-via-symlink/config/prep_buildtree
+ me=prep_buildtree
+ help='Usage: prep_buildtree sourcetree [buildtree]'
+ test -z /home/andres/src/postgresql-via-symlink
+ test x/home/andres/src/postgresql-via-symlink = x--help
+ unset CDPATH
++ cd /home/andres/src/postgresql-via-symlink
++ pwd
+ sourcetree=/home/andres/src/postgresql-via-symlink
++ cd .
++ pwd
+ buildtree=/tmp/pgs
++ find /home/andres/src/postgresql-via-symlink -type d '(' '(' -name CVS -prune ')' -o '(' -name .git -prune ')' -o
-print')'
++ grep -v '/home/andres/src/postgresql-via-symlink/doc/src/sgml/\+'
++ find /home/andres/src/postgresql-via-symlink -name Makefile -print -o -name GNUmakefile -print
++ grep -v /home/andres/src/postgresql-via-symlink/doc/src/sgml/images/
+ exit 0
Note that the find does not return anything.
Greetings,
