How are you distributing your app? I'm assuming you're going to have something
like:
MyApp\
MyApp.exe
MyApp.dll
IronPython.dll
IronPython.Modules.DLL
...
You should be able to also distribute the standard library and just drop it
into a Lib directory next to IronPython.dll:
MyApp\
MyApp.exe
MyApp.dll
IronPython.dll
IronPython.Modules.DLL
...
Lib\
os.py
That lib dir should be on sys.path at startup and so it should be available for
importing.

.exe/.dll???
Hi Michael,
I started out on implementing this, but I am importing maybe a dozen of the
std. library modules, which then import others, and so on. It appears that
eventually, most of the std modules would have to be imported explicitly
(perhaps 400 or so files) which might make for a somewhat cumbersome command
line, incidentally also about 20K characters too long :-). I'm hoping to find a
way to get this to work as well as it did under IP 2.5 / .NET 3.5.
Noah: what kind of problems are YOU having with pyc.py under 4.0? Maybe one of
us can suggest something if we have an understanding of what you're trying to
do.

I've been looking at the .exe's we built - using pyc.py - with IP 2.5/.Net 3.5
and IP2.7 / .NET 4.0. In the 2.7 .exe, it appears that the imports (like "os")
are not being built into the .exe/.dll, but instead are required to be imported
in source form, e.g. "os.py" must be somewhere on sys.path. In the IP 2.5
.exe's we had been building, they would run fine on machines without the IP
standard library installed at all, in other words, with "os.py" not present on
the machine at all. We did notice that the .exe in question went from being 2.9
MB in it's IP 2.5 incarnation, down to 1.2 MB in the IP 2.7 version, and the
newer version requires that the source code for the IP standard library be on
the path. Is this a deliberate change in behavior? We never had to package the
standard library source when we sent out .exe's to customers before
Hmmm... I'm pretty sure I always had to explicitly compile and bundle the
standard library with previous versions of Python. Odd. Anyway, the simple
solution is to ensure that you add any standard library modules you use to the
set you compile and ship.
All the best,

All the best,
Michael Foord
and how do I ensure it gets found from my .exe - is there a specific env.
variable, or the Windows %PATH% e.v., or something I haven't AddReference'd
to????
Thanks,
Ken
