Hi Anders,
thanks for the input. Sadly it'd need far too much effort to have all
of that implemented and regularly updated - especially due to my lack
of knowledge regarding ASN.1 and nbap. Since we're getting regularly
updated precompiled :-( libraries here anyway that transform the nbap
asn1 hex to value notation I'm "forced" to use those. It's not nice
but it fulfills our needs to see what was sent.
That rises another question I'm struggling with:
I have to link the library to libwireshark.so if I'm just adjusting
the existent epan/dissectors/packet-nbap.c. Somehow I "managed"
through my changes in Makefile.* to do that but it also gets
automatically (by ./configure && make) linked to "wireshark" what
leads to strange side-effects with (as I assume) threading - it's
hangs while starting up the GUI. If I link "wireshark" manually
without those library it works fine.
So, my question is: where exactly do I have to add "-I/myincludepath",
"-L/mylibpath" and "-lmylib" to make it configuring cleanly and not
linking the wireshark executable?
Thanks for any help
Martin

Yes, or rather from 3gpp.org.

I'd like to have it added to asn/nbap/.
The file was edited by hand :-(
A possible solution could be to make a diff files between the
incompatible versions to find the incompatable
Asn1 parts then insert that asn1 code with a different name
Like:
Foo_v1::= foo_v1
Then insert a preference: Decode NBAP as V1,V2 etc
And do the necessary changes in the .cnf and ..-template.c to call the
different functions depending on the version.
Do you have an example of some differences and a trace file to
illustrate it with?

Anders
