Re: [cx-freeze-users] "QtCore: No such file or directory" problem - resolution?

[David C. <dav...@gm...>]

OK, the following brutally stupid change fixes the problem for Qt, or at
least, it allows freezing cx_Freeze/samples/PyQt4/PyQt4.app into a runnable
app. I haven't tried it on my real app yet.

This works because, when you install Qt4 using the
qt-project.orginstaller, and then install the latest PyQt4 from
source, the dependencies
in the PyQt4 modules have the form,

    Qtxxxx.framework/Qtxxxx

That is, they are relative paths that start with Qtxxxx.framework. I put
code in _GetDependentFiles() to print out everything it found, and at least
for this test case, the only relative paths were the Qt items. Everything
else was an absolute path. So all I had to do was stick
"/Library/Frameworks/" on the front of those, and all was well.

A more general fix would be to do this only in OSX, and to test for actual
existence in either of two "frameworks" places, and to leave the item alone
if it is not found, something like this (untested):

                    if dependentFile:
                        if not os.path.isabs(dependentFile) and
sys.platform == "darwin" :
                            # check for relative paths to frameworks
                            if os.path.isfile('/Library/Frameworks/' +
dependentFile) :
                                dependentFile = '/Library/Frameworks/' +
dependentFile
                            elif
os.path.isfile('/System/Library/Frameworks/' + dependentFile) :
                                dependentFile =
'/System/Library/Frameworks/' + dependentFile
                        dependentFiles.append(dependentFile)
