The 'userelocatableinc' option works incorrectly on Solaris 10 (and
earlier, presumably). The problem is that the path to the executable
cannot be obtained like on Linux ('/proc/self/exe') or on BSD
('/proc/curproc/file'). But, as suggested by 'almut' on perlmonks
(http://www.perlmonks.org/?node_id=686876). it can be obtained with
'/proc/self/path/a.out'. So the solution (tested and working) is to
have in Configure (currently, around line 15563) something like the
following "if ... fi" snippet added, for Solaris 10:
procselfexe=''
val="$undef"
case "$d_readlink" in
"$define")
...
if $issymlink /proc/self/path/a.out ; then
$ls -l /proc/self/path/a.out > reflect
if $contains /`basename $ls` reflect >/dev/null 2>&1; then
echo "You have Solaris-like /proc/self/path/a.out."
procselfexe='"/proc/self/path/a.out"'
val="$define"
fi
fi
...
I think this also makes $^X return a correct path instead of just
'perl' (I'm not at the office right now, and I forgot to test that).
The technique does not work on Solaris 8, because apparently it does not
support the '/proc/self/path/a.out' mechanism (according to 'almut'). I
don't know about other versions.
Thanks.
