After many issues, I think the above is okay. Now I got errors about rlgl.h line 1200 gives undefined reference to 'sqrtf' and many more raymath.h e.g.
Worth it. The old database uses graphics.h you were inspired by. Because of the need of editing i have to address each character. The old database use extended ASCII. In the new database I have to convert to UTF8 in Raylib (Danish) when showing on the screen, but still save data as extended ASCII because of compatibility. Quite a task for a hobby programmer but doable with Raylib!
So many thanks for a great libray!
