GnuCOBOL (formerly OpenCOBOL) is a free, modern COBOL compiler. GnuCOBOL implements a substantial part of the COBOL 85, COBOL 2002 and COBOL 2014 standards and X/Open COBOL, as well as many extensions included in other COBOL compilers (IBM COBOL, MicroFocus COBOL, ACUCOBOL-GT and others).
GnuCOBOL translates COBOL into C and compiles the translated code using a native C compiler.
Build COBOL programs on various platforms, including GNU/Linux, Unix, Mac OS X, and Microsoft Windows. GnuCOBOL has also been built on HP/UX, z/OS, SPARC, RS6000, AS/400, along with other combinations of machines and operating systems.

Hi! There are more information of install with red hat? I have so many issues with that, and I need install gnucobol in that! Thanks! It's a good project!

For Fedora, dnf install gnucobol, right out of the package repo. For RHEL, or CentOS, I'm assuming the same would work too. That would give you version 2.2, as of Sep 2020+1, I think. You can also use dnf install libcob if you don't need the compiler but need the run-time to run compiled programs. -
Decent language support. Could be nice if the syntax trees were a bit easier to extract, but I managed. Version 3.1 didn't pass all NIST tests for me. Also found an overzealous optimization.

Thanks for the review. We don't pass all NIST tests and skip some, mostly the one related to COMMUNICATION SECTION (not implemented "enough" to pass) and, depending on the question of ORGANIZATION INDEXED used some related tests. If you see errors in `make test`: please report via bug tracker. -
using GnuCOBOL 3.1.2 under windows 7 and works like a charm! but if you try this on Linux eg Void I am only getting a scrolling ERROR ... ERROR what you crackheads? Was so difficult to display something meaningful when there is an issue? get some life .

All CI builds run with GNU/Linux first, and also the main development, so it is unlikely to be broken "in general" there; actually your review is the first note of it getting a scrolling ERROR. In any case a bug report with the actual error you see and the output of `cobcrun -v --info` is likely more useful to fix the issue you have on your local machine than leaving a rating... -
This cobol is easy to use once you get install. The support is very good.

Important project: about 35% of "production" code is in COBOL, and it processes about 80% of all transactions (e.g., ATMs, telephone calls), so making it robust will allow many companies to thrive. Was easy to integrate (and extend) in my COBOL translation project. In need of thorough testing, as the quality is still "Just OK". Wish I had more free time to help :-)
