This might not be the core topic of this list, but I think it's the best
place to put my question as it involves pyside internals.
To be able to distribute a stand-alone program from a python script (that
uses pyside) I have tried the following tools: cxFreeze, py2exe and
pyinstaller. They generate executable files that start without errors. (i
found pyinstaller and cxFreeze to be the easiest to use...)
But the standalone programs (all three!) seem to have a problem with
displaying images (png's seem to load fine, jpegs do not), whereas executing
the python script does not have these problems.
This is strange, since the only dependancy of the program is pyside... (and
the pyside/qt dll's are copied to the distibutable directory) any clue of
what is going on here?
I have compiled the following image viewer script below as a minimal
example:
(One additional note: I tried copying -all- qt dll's into the executables
directory..)
Kind regards,
C.
