Getting Started with z/OS Open Source
Before you begin, make sure you have access to a z/OS UNIX environment and that your environment is correctly configured.
Setting up your z/OS environment
z/OS Open Source tools require z/OS Enhanced ASCII support. This support enables automatic conversion between codepages for tagged files. To take advantage of this support, you need to set the following environment variables:
export _BPXK_AUTOCVT=ON
export _CEE_RUNOPTS="$_CEE_RUNOPTS FILETAG(AUTOCVT,AUTOTAG) POSIX(ON)"
export _TAG_REDIR_ERR=txt
export _TAG_REDIR_IN=txt
export _TAG_REDIR_OUT=txtWe recommend adding these environment variables to your .profile or .bashrc startup script.
Required Tools
To consume zopen community, all you need is a z/OS UNIX system and unrestricted access to github.com.
If you want to contribute and improve the z/OS Open Source Tools
You will need the IBM C/C++ compiler on your system. There are two options:
- Clang
- The default compiler is clang. You can download the pax edition from IBM at https://epwt-www.mybluemix.net/software/support/trial/cst/programwebsite.wss?siteId=1803. This version may be used for development of open source software. Alternatively, if you have IBM Open XL C/C++ installed, you can use it instead of clang.
- XL Clang
- You can download it as a web deliverable add-on feature to your XL C/C++ compiler here.
If you are building Go projects, you will need the IBM Open Enterprise SDK for Go compiler installed. You can obtain it here: https://www.ibm.com/products/open-enterprise-sdk-go-zos
