IBM I GO (based on GO 1.20.5)

This repo is an attempt to compile Go with CGO application on IBM I AIX. I used lot of analysis and research done by other people like

• Micah Kimel
• Mike Measel

and every one involved in the discussion on the following git issue (specially the user rfx77)

golang/go#45017

Special thanks to Norman Koller (RZKH GmbH) to provide required infrastructure and support !!!

Prerequisites

• IBM I 7.4 +
  • I have tested the compiled binary on 7.4 and 7.5
  • Compiled binary might work on lower versions but I have not tried and so I am not sure.
• GCC 10
  • GCC 10 is not available for version 7.2 or lower
  • use command gcc --version
  • There is a possibility that gcc points to older version and gcc-10 points to the newer version
  • In that case we will need gcc-10
  • If gcc is installed but not found, use following command to include open source packages to your path
    • export PATH=$PATH:/QOpenSys/pkgs/bin
• Required yum packages for ODBC (if you want to use ODBC)
  • unixODBC.ppc64
    • yum install unixODBC
  • unixODBC-devel.ppc64
    • yum install unixODBC-devel
  • libodbc2.ppc64
    • yum install libodbc2
  • ibm-iaccess.ppc64
    • yum install ibm-iaccess

Steps

• clone this repo on IBM I
• Setup PATH env variable
  • export PATH=$PATH:{GIT_REPO_CLONE_DIRECTORY}/ibmigo/go/bin
  • export GOROOT={GIT_REPO_CLONE_DIRECTORY}/ibmigo/go
  • export PATH=$PATH:/QOpenSys/pkgs/bin
• Create a tmp directoy in your home dir(remove old one if needed)
  • rm -r /home/{USER}/tmp
  • mkdir /home/{USER}/tmp

Compile your Go app

• GOTMPDIR="/home/{USER}/tmp" CC="/QOpenSys/pkgs/bin/{gcc-10-location}" go build {required parameters} {path to go main package}
