[Ironpython-users] pyc.py and codecs

[rox]

Hey,

a little background:
i am trying here to make sort of compiler helper. idea is to build
dependency tree of project and then just pass all standard library py
files to pyc.py so they would be compiled into application. Result would
be independent from ironpython .NET executable.

the problem:
seems that codecs somehow do not compile right. in compiled binary i
cant use utf-16 codec (i did not test others).

testcase is really simple:

> import codecs
> codecs.open('file.txt', 'r', 'utf-16')
file.txt should exist before testing this. it can be empty, doesnt matter.
running it on ipy interpreter no exception is thrown, but if this is
compiled to executable this is what i get:

Is this something on my end or problem in IronPython itself?
