With a third party file-oriented Xojo module, Xojo 2019R2 has deprecated some old settings (ex MacCreator) and now 64-bit only. I am not crazy but Ive never seen this before. I just ran a build for macOS and get 11 errors in the third party library. Ok, I can probably fix them. Here comes the strange part. I build again but this time with no source code change, a larger number of errors (21) is generated. Same code, one IDE. Anyone seen anything like this???
Could this be a Xojo 2019r2 issue???
try r2.1 then report back
