However, it does not presently do that for Mac frozen apps. However, the current matplotlib uses saner search path for its data files, so it may be irrelevant. I will also note that freezing a windows exe that uses matplotlib is famously difficult. Ironically, the same is true for a Windows exe that uses the win32 package (a package used by many or most python programs on Windows). py2app is significantly smarter than py2exe about finding the necessary files. The only hassles on Mac are: - the need to copy the data files (not a big deal, especially, apparently, with newer matplotlibs that use smarter paths) - apparently the need to explicitly specify the FileDialog module (that one caught me off guard) - also, if one really wants to be safe, one should either delete os.env["MATPLOTLIBDATA"] or set it to the correct path. -- Russell _______________________________________________ Pythonmac-SIG maillist - Pythonmac-SIG@python.org http://mail.python.org/mailman/listinfo/pythonmac-sig
