Re: [PyMCA] Getting started, but encountering some difficulty and a minor problem

[V. A. S. <so...@es...>]

Hi Robert,

What version of PyMca are you using?

1 - A precompiled binary downloaded from sourceforge
2 - A version supplied with ubuuntu
3 - A version built by yourself

The blackening of the tooltips is something specific to your system. The 
library dealing with that is Qt. If you are in case 1, then you should 
try 2 or 3.

The versions shipped as official packages for ubuntu and debian are 
*not* convenient for Cu alloys. You need a 5.X.X version (preferably the 
latesst).

Because of that I supplied with latest official release some 
"unofficial" debian packages.

I would recommend you to install PyMca from its source code. You can 
either download the source package from sourceforge or checkout the 
master branch of the github repository.

For instance:


1 - Download source package from 
http://sourceforge.net/projects/pymca/files/pymca/PyMca5.1.0/
2 - tar -xvzf pymca5.1.0-src.tgz
3 - cd pymca
4 - python setup.py install --user --fisx

should allow to get a proper installation not conflicting with any 
package you might have previously installed.

For further help, one would need to know what type of setup you have 
(monochromatic tube or not).
