Codec Search Function

[James Stroud]

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 "PyInstaller" 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

for workarounds for py2exe.

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.
