[SOLVED] After upgrade autotools segfault

Hello.

I did a system upgrade, pacman -Syu exited with 0, and everything seems fine except since then
all autotools programs (autoscan, autoheader, automake, autoreconf) end in a segmentation fault.

I tried re-installing those programs (e.g. pacman -S automake) but nothing changed.
I did strace but i am not skilled enough to make anything out of it.

So i ask for directions what i can do to find the error.

Regards and thanks,
Alfred

Re: [SOLVED] After upgrade autotools segfault

Hello.

Oh my dear ^^

That ofcorse leaves me with re-installing the system,
since almost everything that has to do with cpan or perl segfaults.
It also makes me wonder if i ever should upgrade again if i want
to avoid the same hassle.

Regards and thanks,
Alfred

Re: [SOLVED] After upgrade autotools segfault

Hello.

I could not recompile perl modules because 'cpan -r' would segfault and simply doing
'pacman -S perl' did not help. I was desperate ^^

Somewhere i found the tip to
# cd /usr/lib
# mv perl5 perl5-alt
# pacman -S perl

after that cpan -r could recompile the modules
and so far everything sems back to normal.

Sorry, but i dont know how to mark the thread as solved,
can somebody please do that?

Regards and thanks,
Alfred

Edit your first post in the thread.  It allows you to edit the title.  Just add [SOLVED] to the beginning of the title.

Glad it is working
