Encountered this when trying to compile larwirecell against wirecell

Hi @HaiwangYu

What version of WCT is this?

Here is my guess, let me know if I get close.

I suspect you are using a common source area to install multiple versions and an incorrect build/WireCellUtil/BuildConfig.h is getting installed due to switching to a new source branch. I believe is possible (wcb bug) even if a ./wcb configure is done after the switch. I think there is some bug that keeps the BuildConfig.h from being updated if it already exists.

If this is still on track, the BuildConfig.h that you have installed is probably from a branch that adds support for ./wcb --with-spdlog-active-level and in that branch you should have a version of Logging.h not like what you show but like:

a5ef5d3fd (Brett Viren 2023-12-01 16:44:57 -0500 16) // #define SPDLOG_ACTIVE_LEVEL SPDLOG_LEVEL_DEBUG
a5ef5d3fd (Brett Viren 2023-12-01 16:44:57 -0500 17) #include "WireCellUtil/BuildConfig.h"

This is git blame from my apply-pointcloud branch. So, there, everything is consistent. But, then switching a branch changes Logging.h but you get stuck with the previous BuildConfig.h.

I believe the fix after you switch to a source branch that lacks .wcb --with-spdlog-active-level is to manually make sure BuildConfig.h is gone

rm build/WireCellUtil/BuildConfig.h
./wcb configure ...
./wcb
./wcb install

Thanks! It seems to be the case. I have two local repos. I will check your solution.
