Description
GnuCOBOL (formerly OpenCOBOL) is a free COBOL compiler. cobc translates COBOL source to executable using intermediate C, designated C compiler and linker.
OpenCOBOL 1.1 became GNU Cobol 1.1 in 2013. Official releases at ftp://ftp.gnu.org/gnu/gnucobol
GnuCOBOL 2.0 is on its way to pre-release. All versions, old and new, hosted here.
A programmer's guide, by Gary Cutler, and other documentation, is indexed at
http://open-cobol.sourceforge.net/
OpenCOBOL was written by Keisuke Nishida and Roger While, from 2001 to 2012.
GnuCOBOL is also authored by Simon Sobisch, Sergey Kashyrin, and Ron Norman.

So far no complaints. Have used it to write a farily extensive program on Linux and FreeBSD and it works just great!

great product and toolset for migrating, integrating and transforming these infamous cobol beasts on the hosts. The openness of C enables amazing portability aspect. If you have the option of chosing a platform/operating system, I strongly recommend to go along with one of the unix brands (ubuntu, linux) and rather restrain from windows - where the cygwin etc issues often pose problems. Of course - be honest to your self - you cannot expect the same support efficiency and reaction times like for example from MF-Cobol ... but it's still amazing enough.

Great compiler for every job production and test. perfect

This GNU Cobol is an exercise in frustration for the Windows user that don't like to use Linux. You either have to use CYGWin and then it will give you an error message when you try to compile something as easy as Hello World. This is utterly ridiculous in the ease of the software.

Good alternative to commercial cobol compilers.
