[El] Missing dependencies

Thu Aug 19 11:16:06 EDT 2010

Hi Micha,

I'm currently on the road, so I won't be able to look at it in more details
before a few days, but just to give you some information:

- EL GIS depends on and is tested with EPEL. RPMForge is a great repo, but
it doesn't have a clear policy with regard to updating or not the core
distrib. (I personally tend to enable it package per package). So I guess
that you should look at mixing EPEL and RPMForge

- Python extensions are broken in QGIS. Python 2.4 is too old I think. I did
not succeed yet in using python26 from EPEL. Help here would be great (or we
simply wait for the imminent release of RHEL/CentOS 6 which will make things
easier...)

- ELGIS is built and tested against CentOS 5.5. Could it explain some of
your issues?

- did you try the latest Grass version in elgis-testing?

Sorry for not replying inline but I can't from my phone :(
I'll try to look in more details as soon as I can.

Cheers,

Mathieu

I'm working on a fresh installation of CentOS 5.5 i386, and trying to
use the elgis repo. It seems there are still missing packages. Here's
my experience so far:

(apologies in advance for the long post...)

1) Whenever I install CentOS I first add the rpmforge repository. In
rpmforge there are already packages for proj and geos. If you get
these, instead of the elgis packages, then the elgis gdal
installation will fail because of missing dependencies. There are two
ways to get around this: either temporarily disable rpmforge, and
install proj and geos from elgis, or else set up with yum-priorities to
have the elgis repos of higher priority (lower number) than the
rpmforge repo.

2) When I got to installing gdal, I was still missing these 5 rpms:
libgeotiff, ogdi, hdf5, cfitsio, and gpsbabel. I found all of them on
the pbone.net website. After installing all of them, then I could get
gdal, grass and qgis setup.

Here's my step-by-step procedure (watch out for line wrapping in the
email)

Can we get these packages built into the elgis repository? Or are they
available from somewhere else?

Now two questions:
QGIS works but no plugin-installer :-(
I get this error on application startup:
-----clip------
Couldn't load plugin plugin_installer due an error when calling its
classFactory() method

Traceback (most recent call last):
 File "/usr/lib/python2.4/site-packages/qgis/utils.py", line 141, in
startPlugin plugins[packageName] = package.classFactory(iface)

line 33, in classFactory from installer_plugin import InstallerPlugin
 File

Python version:
2.4.3 (#1, Sep  3 2009, 15:37:12)

-----end clip-----

Anyone know what's wrong here?? Am I missing some python package?

And next a question regarding GRASS. In the wxpython interface the
vector digitizer is not available. This happens, AFAIK, for one of two
reasons: either GRASS was configured without the --with-cxx option, or
the version of swig (python-c++ bindings) is too new. Checking the
GRASS source spec file from elgis, I see that --with-cxx is included,
and the swig version on CentOS is 1.2.29. Should be OK (If swig is newer
than 1.3.26 then the vector digitizer functionality disappears). BTW,
in the tcktk interface, the digitizer works fine.

Thanks, and again, sorry for so many questions right at the start
