Wasn’t hard to get working…but more work than expected in 2021. I think it was 1 click in Manjaro. Mint is still on GnuCOBOL ver 2. GnuCOBOL not available in Discover, but was in YaST Software. So Install gnuCOBOL which also installed libcob4. A libcob-devel was shown but not selected by default, so I didn’t select it! So after trying to compile a gnuCOBOL program it fails and tells me it needs gcc. So I installed gcc. Try compile again but now it tells me some COBOL header file is missing. Go back to original install and select libcob-devel. Finally a successful compile.
This version was 3.1.2.0. Nice to see version 3 is finally official…no longer a release candidate.
