[pygccxml-development] KeyError in Py++

[Sergey . <sr...@gm...>]

Dear Py++ developers,

   I am using Pygccxml and Py++ to generate Python bindings for our C++
project and really like it. You guys are doing a great job, thank you for
you work!

   After upgrading to version 1.0.0 I started to occasionally receive the
following error when trying to execute module_builder_t (see log below).
Strange thing is that it appears only with certain combination of headers
files, when each of them separately could be bound without a problem. Also,
trying to compile with older version of gcc (3.4.6) tends to produce this
error for almost any combination of header files. Any idea what could be
wrong with my setup or my code?

    Thank you in advance,

Sergey.

I guess nothing, but to be sure I need to see how you construct
module_builder_t class instance.
Do you pass single file a list of files? My guess - you pass list of files.
I suggest you to create a header file, which includes all others and
pass it to module_builder_t.__init__. This should fix your problem.

If it does, it could be nice if you can send me (privately) gccxml
generated files for every file, you pass to module_builder_t and than
xml file of the file, which includes all.
I think this will help me to find and fix the bug.

Thanks

  - Yes, this is correct, I pass list of files.

   - Good idea, I will try that soon. I will let you know how it goes. I
will have to contact my boss before I can send you any files, but I guess
this should be OK.

    Thank you for your help!

Sergey.

I don't need your code, but a code that reproduce the problem. It
could be nice, if you can send very simple code.

You are welcome.
