@david_s5 you just saved me a lot of time by getting me to try to fix my build situation. I had a problem where if I ran “make” from the build directory once, it worked. But if I ran it again it was failing. This was because of some file paths in some of the .d files. I was thinking maybe converting my PATH to DOS8.3 format would maybe change the situation… worth a try at least. So I did, and it was now building over and over perfectly. But as a test, I put my PATH back to the normal long version expecting it to break again but it did not. Still builds perfectly. There must have been some updates to the make file that I wasn’t aware of… so thanks for inadvertently saving me a ton of time! I had to basically clean all build directories before EACH build prior to now… that really sucked.
