Hi Armin,
Fwiw the patch I have in mind would look like
this: http://bpaste.net/show/87755/
this line:
- 'gbl' : 'pythonify.gbl',
can not be removed, as w/o it 'gbl' will not show up at the module level.
and I have no clue about which
part of the code contains an error message about being circular.
Looks like this (and I get it when running the translation with the patch
as above, but with 'gbl' still in the applevel defs). Sorry, the message
said recursive, not circular:

But again, the real problem is that startup() still runs immediately when I
type './pypy-c' and not when 'import cppyy' later on the prompt, so even if
the above problem gets solved, I still can't raise an ImportError in startup()
when the library is missing.
That is, if I leave the setup as-is and simply call verify_backend() in the
startup() function in cppyy/__init__.py, this is how it looks if the library
is missing:
$ ./pypy-c
Traceback (most recent call last):
File "app_main.py", line 52, in run_toplevel
ImportError: missing reflection module rflxlib.so!
Python 2.7.3 (2377fb34943d+3ef424d4281f+, Mar 30 2013, 03:53:47)
[PyPy 2.0.0-beta1 with GCC 4.6.2] on linux2
Type "help", "copyright", "credits" or "license" for more information.
And now for something completely different: ``things worked nicely till today
just by chance''
>>>>
(And copying rflxlib.so to an accessible location nicely makes the error
message go away, so the checking does work properly, unless that message I
got on the prompt is being prophetic. :) )
Thanks,
Wim
