Re: Profligacy of messages/ link errors building 5.99 on Windows 10/Msys

 

I've been playing around with this and there is definetly something
amiss.  I don't get the build errors on release builds but I do see them
with debug builds (CMAKE_BUILD_TYPE=Debug).  Downgrading swig from
4.0.2-1 to 4.0.1-3 didn't help.  Interestingly the 5.1 branch builds
just fine so I suspect a recent change in the one of the CMake config
files is to blame.  I don't remember seeing any swig changes recently.
