building against system libs and external pythons about cloudmap HOT 9 CLOSED

I updated the package to fix the problems with the dependencies and the version number.

But what is the problem with the projection?

Great, thanks a lot!
Without the patch on satellite.py, I am getting the following error:

and I have been using a system-wide install of pyproj-1.9.5.1 against libproj4 version 4.9.2. It seems that the proj_dict dictionary is required to have a and b with these versions.

Cheers,
Chris.

I try to reproduce your error, but with the same libproj4 version (4.9.2) and pyproj-1.9.5.1 I am not able to get the error. What is your pyresample version? I am using 1.7.0 (the current one).

from cloudmap.

Yes, same here, this is pyresample-1.7.0. That's weird, I'll try to figure out what is wrong with my install then!
Thanks for the feedback!

from cloudmap.

Can you start with a fresh virtual environment and install CreateCloudMap plus all dependencies there by pip?

By the way, these looks somehow similar:
pytroll/pyresample#26
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=792068
http://lists.maptools.org/pipermail/proj/2011-October/005905.html
(the last link includes something about an initialization file. What could that be?)

from cloudmap.

Yes, within pip only, in a clean environment, it works fine. It seems that I indeed miss some proj4 or pyproj default files. I'll try to figure it out and post it here. Thanks for the help!

from cloudmap.

Ok, this is a well-known libproj issue:
OSGeo/PROJ#274

I am closing this issue, thanks a lot for your help!
Best,
Chris.

from cloudmap.

To be specific, this file should be present for pyproj and proj to use default values:

/usr/share/proj/proj_def.dat

from cloudmap.

Thank you for traking this down.
