Bug 338617 – sci-geosciences/mapnik builds ok, but missing python file

• Product: Gentoo Linux
• Status: RESOLVED OBSOLETE

[Description John L. Poole 2010-09-24 22:58:00 UTC]

emerge of  sci-geosciences/mapnik concludes without error.  According to the MapNik documentation at http://trac.mapnik.org/wiki/GettingStarted:

  Make sure you have mapnik installed. Depending on your installation path you may need to modify your PYTHONPATH, /etc/ld.so.conf or export LD_LIBRARY_PATH, or whatever your system requires.

  The simple check is to start python interpreter from a command line by typing python and then just type:

  >>> import mapnik

  and if you don't see any complaints, you're on the right track. If you do, you have to check your installation again. 



Reproducible: Always

Steps to Reproduce:
1. python
2. import mapnik


Actual Results:

Please try running:
$ /usr/lib64/mapnik/input/ogr.input
$ /usr/lib64/mapnik/input/gdal.input

That's normal. Doesn't look like having broken linkage.

[Comment 4 Steve Arnold 2010-10-17 23:26:28 UTC]

"import mapnik" gives me no errors, and no output at all...

[Comment 5 Tomáš Chvátal (RETIRED) 2012-05-26 09:46:41 UTC]

Seems to work with 2.0.1 at least here.

Please reopen or open new bug if you can reproduce it with that version.

I successfully emerged mapnik:

[I] sci-geosciences/mapnik

     Installed versions:  2.0.0(07:15:19 05/26/12)(cairo debug gdal postgres python sqlite -bidi -doc -geos -nobfonts)
     Homepage:            http://www.mapnik.org/
     Description:         A Free Toolkit for developing mapping applications.


I had to tweak some settings and add "python" as a use variable to dev-libs/boost.

After all that, I tried an assay (with the new 2.0 tool mapnik-conf and nothing happened.

hermes ~ # mapnik-config -v

hermes ~ # 

This is a different issue and warrants a different bug which I may get around to logging at some point; however, I did not want someone visiting this bug to think all is well by a lack of comment by me.

Since this really wasn't "Fixed", I'm changing the status to "Obsolete".
