Success on MAC OS X

[Damon Hermann]

In case anyone is interested in installing on MAC OS X Catalina
1. Download latest version of GNUCobol
2. untar into directory of your choice
3. download BerkelyDB from oracle
* untar
* cd into the BerkelyDB/build_unix folder
* run '../dist/config'
* run 'make'
4. Change to the GNUCobol Folder
You may have to BREW install a couple of libraries. I found I had to install GMP and MPIR libraries with brew
5. run ./configure --with-db=/usr/local/BerkeleyDB.18.1
* or the version of BerkeleyDB you downloaded
6. run 'make'
7. run 'make install'
8. cobc -v

AND YOU'RE DONE!

You possibly want to check with cobc --info if you have a full-featured compiler - or need to add curses, libxml2, libjson-c / cJSON to achieve this.
Note: these (ok all but curses) are new optional dependencies - looking at DEPENDENCIES gives a good picture.

[Simon Sobisch]

So you likely want to add libjson-c (or just place cJSON.c+h into the libcob folder before running configure) and include BDB or one of the other handlers for ORGANIZATION INDEXED - in any case see DEPENDENCIES file for details.

Thanks for the heads up. Reconfigured and all is good.
