I just discovered that the fltk 1.1.9 ebuild is missing a debug use flag. The attached patch corrects this. I have tested it on my system, and it seems to do what it's supposed to do. Reproducible: Always Steps to Reproduce: 1. Compile fltk 1.1.9 2.look for debug information 3.fail
Created attachment 201055 [details, diff] Patch to enable debug use flag.
Thanks for reporting. Fixed in 1.1.10.
