    Codec Search Function

    Hello All,

    I'm using pyinstaller 1.0 (stable) on win32xp and it is not able to find
    the codec for several encodings (hex, base64, etc.). I resorted to
    writing my own for hex, just to see if I could get my program deployed.
    But I think a more permanent solution would be to get pyinstaller
    working right.

    I tried the latest release (unstable version), claiming that it solved
    the problem, but it had problems finding a search function:

    LookupError: no codec search functions registered: can't find encoding

    I looked at the documentation for codecs.register , and it was really not
    clear exactly how I was to create the search function that needs
    registering. Any help would be appreciated.

      I was able to get all the functionality I needed from binascii.

          Do you have a small reproducible sample which shows the problem? With
          PyInstaller SVN version, the problem appeared to be fixed for the testcases I
          had.

          BTW: putting "PyInstalle r" in the subject of the mail for PyInstaller-related
          mails (and/or mailing to the PyInstaller mailing list) would be preferred to
          get a quicker answer.

          Thanks!

              How do I get the SVN version? Maybe that is not the one I have. This
              crashes on the version I have (complete program listing):

              "abcde".encode( 'hex')

              LookupError: no codec search functions registered: can't find encoding

              I am using the latest enthought python and the latest snapshot of
              pyinstaller.

                  looks like pyinstaller isn't clever enough to bundle the relevant encodings
                  by default. see

                  http://starship.python.net/crew/theller/moin.cgi/EncodingsAgain


                  for workarounds for py2exe.

                      svn export svn://pyinstaller.hpc f.upr.edu/trunk pyinstaller

                      I tried it and it works for me with a default spec file. Try again with latest
                      PyInstaller from SVN, or otherwise please enter the "buildXXXXX " directory made
                      by PyInstaller through the build process, and execute "ArchiveViewer. py
                      out1.pyz" (ArchiveViewer. py is shipped with Python). It will display a list of
                      all the packaged modules: in my list, 'encodings.hex_ codec' appears.
