Classification

Requirements

Hardware

At least 200 MB hard disk space

More than 256 MB RAM

More than 1 GB hard disk space and 512 MB RAM recommended

Software

gcc and g++ 4.4.X or later

Linux-series OS

2. Verifying Available Disk Space

Before installing OFCOBOL, verify available disk space in the Linux system. To install OFCOBOL, at least 200 MB hard disk space must be available.

To verify available disk space in a Linux system, execute the df command at the Linux prompt.

$ df -k

The following is the result of executing the previous command.

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

The result shows that the /home directory size is 899263880 KB and 651491856 KB (77%) is in use and 202092000 KB is available.

3. Verifying System Environment

To install OFCOBOL, gcc, g++ 4.4.X or later version must be installed.

The following shows how to check gcc and g++ versions.

gcc

$ gcc --version
