Python 3 SyntaxError from long literal 0x950412deL in po/msgfmt.py

[peterjc]

README says "Python 2.7.2 or later is needed." which implies Python 3 should work.

However, installation under Python 3 fails, first problem is at line 82 in file po/msgfmt.py

    output = struct.pack("Iiiiiii",
                         0x950412deL,       # Magic
                         0,                 # Version
                         len(keys),         # # of entries
                         7*4,               # start of key index
                         7*4+len(keys)*8,   # start of value index
                         0, 0)              # size and offset of hash table

This prevent installation under Python 3, e.g.

$ pip3.5 install linkchecker
Collecting linkchecker

+1, just ran into this issue today

+1 Same issue today

Seems to be a doc bug Website: "Python 3 is not yet supported." Nevertheless python3 support should be high priority imho. Is there a similar lib supporting py3?

[reagle]

I had the same problem with python3, and can't install with python2 either.

@reagle your Python 2 problem is something different, can you open a new issue for that instead?

Update: You are probably seeing https://github.com/wummel/linkchecker/issues/649

[reagle]

@peterjc okay, thanks.
