Re: [Audacity-devel] local build problem on Windows

Paul, the problem is that using “/FI” to force include configwin.h overrides the method used by CMake to include the precompiled headers. I’m trying to devise some sort of workaround, but I don’t think it’s gonna be pretty.

Yea, it broke the use of precompiled headers on Windows.  Looking into it…

Problems with my local build, using VS 2019, and using VS's cmake, as in the build instructions in win/build.txt.

Starting with the recent commit: 794f4e5877195e28afb230f2cdff166410fd5e37,

I'm getting the build errors shown below,

David.
