QGIS » QGIS Application

Can you give more details please?

Commit 576c0409 (SVN r13885) was developed and tested on my 64-bit OpenSUSE 11.2 system.

Yes, the error message is:

Warning: Couldn't load Python support library: Cannot load library /usr/lib/qgispython: (/usr/lib/libqgispython.so: cannot open shared object file: No such file or directory)

The library is actually in /usr/lib64, not in /usr/lib.

The standard configuration wouldn't install into that directory - but QGIS_LIB_SUBDIR is configurable - so we should use the configured value. Does the attached patch help (also for #2618)?

Almost :) I think that the second attached patch will do it.

A question: should QGIS_LIB_SUBDIR be used for all systems, including the current two special cases in the code for Mac and Mgwin32?

That is, rather than the defines, should the code just be

pythonlibName.prepend( [[QgsApplication]]::prefixPath() + "/" + QGIS_LIB_SUBDIR + "/" );

Well, for OSX there is the xcode project, which is used to create the packages. I don't know if it has/uses QGIS_LIB_SUBDIR. I also never uses MinGW to build QGIS. So IMHO better save than sorry ;)

(with a suitable Qt function to get the right path separator?).

I don't think we need to care about that. On Windows boths seperators work and IIRC in some circumstances Qt wouldn't work with backslashes.

The second patch is working for me, didn't try the first one.

QGIS_LIB_SUBDIR is used on the Mac build, in both cmake and xcode.

QGIS_LIB_SUBDIR is used on the Mac build, in both cmake and xcode.

But the code

#if defined(Q_WS_MAC)
  pythonlibName.prepend( [[QgsApplication]]::prefixPath() + "/lib/" );

in qgisapp.cpp is hard-coding in /lib/ for the location of the qgis libraries, rather than using QGIS_LIB_SUBDIR (5baeed1c (SVN r13913)).

The second attached patch has been applied (5baeed1c (SVN r13913)). The code for non-linux system remains unchanged (probably best to let someone who compiles under Mac or Mingw32 to change them if necessary).

I meant that it is defined, and used, within the project/cmake files, so it is available to use in source files. Go ahead and group Mac and Linux in qgisapp.cpp like in the original.
