Re: Using DISSECTOR_SUPPORT_SRC

Alright, this will help. However it seems as though wireshark isn't
even trying to build my file. As I said, I added it to the
DISSECTOR_SUPPORT_SRC array in my Makefile.common, and reconfigured
and all that jazz, but wireshark doesn't touch it. Clearly I have
missed something else.

I think the problem is that you are trying to extern a static variable.
Static variable has a scope in its own file and can't be accessed anywhere
else...

Hello,

I have a perfectly working dissector, but I wanted to move a very
large struct I have in it into its own C file. So I moved it (still
keeping it static), declared an extern to it in the original file, and
added the new c file to DISSECTOR_SUPPORT_SRC in Makefile.common in my
plugin's directory. After (re)compiling wireshark, I get an undefined
symbol error at runtime referencing this moved struct. So I tried
moving the filename into DISSECTOR_SRC instead, and this also failed
with the same error. Clearly I am doing something wrong.

Have I missed a necessary file that I need to edit? Or am I going
about this the completely wrong way?

Any help is greatly appreciated.

Thank you,
Jeremy
