[mcstas-users] Perl problem Ubuntu 11.10

[Willendrup, Peter Kjær]

Hello Jean-Francois,

I just upgraded my ubuntu to 11.10 and now get the following error

/usr/bin/perl: symbol lookup error: /usr/lib/libpgplot.so.5: undefined symbol: XOpenDisplay

(this of course means I cannot plot anything)

any clue?

There seems to be a problem with the perl-PGPLOT provided with the newest Ubuntu… Will file a bug-report with them. It turns out there is a work-around here:

1) Install a few packages:
apt-get install gfortran libextutils-f77-perl libx11-dev

2) Get, build and install perl-PGPLOT from CPAN:
wget http://search.cpan.org/CPAN/authors/id/K/KG/KGB/PGPLOT-2.21.tar.gz
tar xzvf PGPLOT-2.21.tar.gz
cd PGPLOT-2.21/ && perl Makefile.PL && make && sudo make install

Cheers,

Peter
