Re: [Py2exe-users] catia typelib problem

First, Mark, you are correct that I meant to say I'm now trying solution
1, not solution 2.

Second, you are correct that my problem was a TLB that I was directly
requesting.  I stumbled across the solution while hacking at makepy,
accidentally causing it to tell me which TLB it was unable to load.  Now
I can freeze and distribute applications that interface with CATIA !
This is awesome !

This is off-topic here, but for what it's worth this is what I did to
makepy.py:
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
	def GenerateFromTypeLibSpec(snip):
		...snip...
		if type(typelibInfo)=3D=3Dtype(()):
		# Tuple
		typelibCLSID, lcid, major, minor  =3D typelibInfo
        	#### I added this try-block around the existing code
        	# It causes py2exe to spit out an error message telling
me which typelib it couldn't find.
        	# Then I can remove that TLB from the list in setup.py
		try:
		    tlb =3D pythoncom.LoadRegTypeLib(typelibCLSID, major,
minor, lcid)
		    spec =3D selecttlb.TypelibSpec(typelibCLSID, lcid,
major, minor)
		    spec.FromTypelib(tlb, str(typelibCLSID))
		    typelibs =3D [(tlb, spec)]
		except:
		    typelibs =3D [] #### new line
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

Then, when I ran py2exe and it tried to import the gen_py modules it
threw the following error:

Previously, py2exe would run without complaint, then would fail at
runtime.  But the last line above told
me what the problem really was.  I went into my setup.py and commented
out that one typelib (which=20
luckily isn't one I need) then reran py2exe, and after that the frozen
executeable didn't fail at run time.

Interestingly, the footnote of solution 2 appears incorrect.  It asserts
solution 2 itself doesn't work - but I believe it should work fine.
It's is unsuitable for some applications though, but is regardless of
py2exe.

Also, I'm a little confused about solution 3.  Solution 1 does *not*
require the typelibs to be installed on the target machine - that is the
point.  It is possible, for example, to have Office installed, but not
all the typelibs necessary to implement a plugin.  That option should
mean Python never needs to load any typelibs on the target machine (and
therefore obviously avoids depending on installed typelibs).  Regarding
newer versions of the typelib, that is only a problem if the vendor
actually breaks old interfaces - but either way, it should be possible
to include multiple versions of the same typelib.

OTOH, a problem spambayes is facing is that *developers* may not always
have all typelibs installed.  Eg, spambayes ships with files generated
from the Office2k typelibs (as that still works with newer versions of
office) - but many people only have later versions installed.  If
spambayes ships with only the newer versions, it will no longer work for
users of Office2k.  We need a strategy that allows the generated files
to be checked into source control, but still be recognised by py2exe.

I really need to document that better, with examples.

Did you mean solution 1?  Solution 2 does not involve py2exe options.

Ack - 102!  That is amazing.

The problem you reference has been fixed - but I don't think it applies
here.  The traceback indicates that a typelib you directly requested -
so one of the typelibs you asked for isn't installed on your machine.
