ghostscript version fix

Development matplotlib-devel
1

Hi all,

I just installed mpl on ubuntu gutsy, and got errors after setting text.usetex : True and ps.usedistiller : ghostscript. The problem seems to be in checkdep_ghostscript() in init.py, specifically the command ‘gs -v’ (should be replaced by ‘gs --version’).

For my system I get:
$ gs -v
GPL Ghostscript SVN PRE-RELEASE 8.61 (2007-08-02)
Copyright © 2007 Artifex Software, Inc. All rights reserved.

and:
$ gs --version
8.61

Below I give a modified version of checkdep_ghostscript() that should work for all version of ghostscript.

Cheers,
Ralf

def checkdep_ghostscript():
try:
if sys.platform == ‘win32’:
command = ‘gswin32c -v’
else:
command = ‘gs --version’

    stdin, stdout = os.popen4(command)
    line = stdout.readlines()[0]
vtest = '.'.join(line.split('.')[:2]) # deal with version numbers like '7.07.1'
float(vtest)
    return vtest
except (IndexError, ValueError):
    return None

Thanks for the report. This was already fixed in svn, but not using --version,
which looks like a better solution. Could someone using AFPL ghostscript let
us know what is the output of gs --version?

gs --version works with AFPL. Could someone please check that this works on
windows: gswin32c --version

Yep. Works.

C:\WINDOWS>gswin32c --version
8.51

Thanks. I updated the gs version checker in svn.
