[Kmymoney-devel] Two instances at once, was: Debugging plugins

[Jack]

I've just tried this again, and it's still not working quite as I  
want/expect.  Hopefully I'm just missing some step or environment  
variable.

I don't think I ever clarified that I'm only working on Linux  
(Gentoo).  Once I do get it working here, I might think about trying on  
Windows, but that's not my primary goal.

As I said before, I use "cmake ." and have now set the install dir  to  
/home/jack/install, using the full path because when I tried  
../../install (to keep it out of the source tree) it somehow had the  
../../ part twice in the install path, and so put everything one level  
higher than I intended.

or in my case /home/jack/install, right?

While this clearly runs the newly built version, I don't believe  
everything else is also coming from the new install directory.  For  
example, I'm currently testing the Print check plugin, and it's  
configuration dialog is still defaulting to /usr/share/apps/... instead  
of /home/jack/install/share/apps, as I would expect or desire - is  
there some other environment variable to set?  I've started reading the  
docs on techbase, but I haven't yet seen anything that tells me where  
I've gone wrong.

Am I correct that unsetting is not important, as long as I run  
ksyscoca4 with the vars set correctly before I run any particular  
version?

I suppose it might save me some grief, but I don't use an IDE.  It's  
just emacs and typing commands.  With editing the docs, I don't always  
do a full compile, just run meinproc and khelpcenter to see the updated  
manual.
