Jon Siwek created BIT-1302:
Summary: configuration of dynamic Bro plugin easily desynchronizes with Bro's configuration
Project: Bro Issue Tracker
Issue Type: Problem
Components: Bro, bro-aux
Reporter: Jon Siwek
Any way for a dynamic plugin to automatically detect Bro's CMakeCache.txt has been changed since the last time it did a "load_cache" so that it can re-run the CMake configuration process?
Maybe a hacky way would be to force the top-level/skeleton Makefile of the plugin to always do a `./configure` or a `touch build/CMakeCache.txt`.
The specific problem I ran in to was
1) do a plain `./configure` of Bro
2) configure/build a plugin (e.g. I was using btest/plugins/file-plugin)
3) change my mind and do a `./configure --enable-debug` of Bro.
4) (re)building the plugin still uses the original compiler flags inherited from Bro's CMakeCache, but it's really important that it be using the same debug flags. In this case not too bad to realize that ABI of the Val class depends on -DDEBUG, but was still pretty unique/subtle to trace the resulting crashes back to the difference in compile flags between Bro and the plugin.
