Hi there, I've come across your repository in my search for an up-to-date method of building an asn1 packet dissector plugin for Wireshark, since like you mention, the current instructions are nonsense since they are over a decade out of date.

I've cloned this repository into the plugins folder, added /plugins/epan/toyasn1 to the PLUGIN_SRC_DIRS in the CMakeLists.txt, however when I run "make plugins" in the build folder it complains that it cannot find packet-toyasn1.c. Do you know why this file is not being generated, and what I need to do so it can be? (Tested on wireshark 3.4.7 and 3.1.0).

Many thanks - James

I installed the missing libs it was complaining about however it still complains that "packet-toyasn1.c" is missing. There appears to be a packet-toyasn1-template.c which I assume is used to generate this, so perhaps it's not being generated for some reason?

Yepadee commented 3 years ago

I think I may have sorted the issue, Apparently I also needed to run "make generate_dissector-toyasn1" before running make. Do you know how I can use this dissector, since it does not appear under "decode as"?

Yepadee commented 3 years ago

Found the dissector appears under decode as once setting a port in edit -> preferences -> protocols -> toyasn1 :)
