Pre-installation Tasks

This chapter describes tasks and checks to perform before installing OpenFrame PL/I.

1. System Requirements

The following are the hardware and software requirements for installing OpenFrame PL/I.

Category Requirement

Hardware

Minimum 1 GB of hard disk space

Minimum 512 MB of memory

Software

gcc, g++ 4.4.X or later

Linux OS

2. Verifying Available Disk Space

Verify the amount of free disk space in Linux before installing OpenFrame PL/I. A minimum of 300 MB of free space is required. To check available hardware space in Linux, execute the df command at the Linux prompt.

$ df -k

Executing the command outputs the following:

/dev/mapper/vg_oflinux64-lv_home 899263880 651491856 202092000 77% /home

The result shows that 651491856 KB out of 899263880 KB of the /home directory space is in use. 202092000 KB is available for use and 77% of the total capacity is in use.

3. Verifying System Environment

Check that 4.4.X or later version of gcc and g++ are installed on the system before installing OpenFrame PL/I.

Check the gcc and g++ versions using the following commands:

  • gcc

    $ gcc --version
