Hi,

I am trying to cross-compile the wireshark source code to build tshark binary for embedded platform. I could able to cross-compile the code but the size of the "libwireshark.so.13" is 90Mb after stripping.

I would like to know the process to unregister some of the protocols in a cleaner way.

Please, suggest the best way to unregister the dissector in the source code.

I did remove the source file entry from the epan/dissector/CMakeLists.txt but there were compilation error and lot of "undefined reference to" error.

Any help will be appreciated!.

Thanks, Nousi

Editing CMakeLists.txt is the only way I'm aware of, but there are dependencies between dissectors that aren't expressed in CMake so you will have to be careful in what you remove.

If 90 MB is an issue you might want to seriously consider using tcpdump instead of tshark. Capture on the embedded OS & analyze elsewhere. Or consider remote capture (e.g. RPCAP) on the device.
