Known Issues

Fedora

Fedora by default doesn't have Python3 and Pip3 installed. And the install process need install pythondev for install some packages.

If you does not have Python installed we recommend to you execute

    sudo dnf install python37
    sudo dnf install python3-devel

After that test that everything is correctly installed checking the version with

>> python3 -V 
    Python 3.7.5
>> pip3 -V
    pip 19.0.3 from /usr/lib/python3.7/site-packages/pip (python 3.7)

Sometimes pip3 is redirected to other path and old version. For fixing that invoke

sudo rm -rf <path_wrong_version>

z/OS

There are numerous problems with the (multiple competing) ports of Python to z/OS. All versions of z/OS Python routinely regress, often introducing, resolving, then later re-introducing character encoding problems. Furthermore, an install process that worked on one level of Pip may not work with a subsequent level of Pip. Its a mess.

"Known Good" Python Configurations

The best results we've had in installing CLAI on z/OS were with IBM Open Enterprise Python for z/OS 3.8, using Pip3 >= 20.0.0.

The following additional configurations are known to work to some degree or another:

  • IzODA Python 3.6, but only with a backlevel Pip3 (verified with Pip3 v9.0.1)

With any of the above configurations, you can perform installation using the instructions in README.md, or you can run:

(bash-4.3)USERID@ZOSYS:~> cd clai
(bash-4.3)USERID@ZOSYS:~/clai> make clean
(bash-4.3)USERID@ZOSYS:~/clai> make install

Known Problems

General

  • The path to the env program must be /usr/bin/env
    • If this is not the case, your system administrator will need to create a symbolic link: ln -s /bin/env /usr/bin/env

IzODA Python 3.6

  • In order for install/uninstall to work properly your .bashrc and .bash_profile files must be tagged either ISO8859-1 or IBM-1047 beforehand
  • The zmsgcode plugin fails to work due to an SSL validation failure
