Encountering missing sourcefiles when building postgres on windows

Hello List,

I'm trying to build postgres on Windows 11 Enterprise / Visual Studio 2022 Professional, so I basically followed the instructions, installed the devenvironment (flex, bison, perl, ...), got the sources from git (I've tried master and REL_15_2 branches) and ran /src/tools/msvc/build

The buildprocess itself seems to work, but I am encountering quite a lot of missing sourcefiles (and also headers) as the errors tell me:

I've also downloaded the 15.2 Tarball where some of these sourcefiles are contained and copied them each by each into the according locations. This works for most of these errors, nevertheless one file keeps missing, it's 'specparse.c' which belongs to the isolationtester test. Because of that my build doesn't run all the way through.

The purpose of my endeavour is to get windows builds of some Foreign Data Wrappers I'd like to use in our projects, mainly the jdbc_fdw. Also we want to gain more knowledge in building postgres on windows . So I would appreciate any help to get the very basic building process up and running as intended.

Best regards
