Software Requirements

Before installing this product, you must have the following software installed on your computer:

• Xterm, the terminal emulator for the X Window System, is part of your UNIX/Linux distribution but is not installed by default. Use your UNIX/Linux installation media to install it.

• On SUSE 12, you can only install and use the 64-bit version of Visual COBOL.
• The pax archiving utility is required by the setup file. Pax is distributed with most UNIX/Linux systems but, if it is missing, you must install it separately. To verify pax is installed, run pax --help or pax --version at the command line.
• Required libraries for Red Hat and SUSE Linux platforms - the installer checks that both the 32-bit and 64-bit libraries listed below are installed on both 32-bit and on 64-bit Operating Systems for this product to install and work correctly.

  If installing on a 64-bit OS, the 32-bit libraries are not installed by default and must be installed before you start the installation.

  Table 1. Default Libraries.

  The following table shows which of the required libraries are not installed by default on the specified platforms - X indicates the libraries are missing.

  Library	32-bit Library Name	64-bit Library Name	s390 Library Name	Platform
  				SUSE 12¹	Red Hat 6.x	Red Hat 7
  glibc	glibc-*.i686	glibc-*.x86_64	glibc-*.s390		X	X
  libgcc	libgcc-*.i686	libgcc-*.x86_64	libgcc-*.s390		X	X
  libstdc++	libstdc++-*.i686	libstdc++-*.x86_64	libstdc++-*.s390		X	X
  glibc-devel	glibc-devel-*.i686	glibc-devel-*.x86_64	glibc-devel-*.s390		X	X
  gcc2	gcc*.i686	gcc*x86_64	X	X	X	X

  • ¹ On SuSe 12, you can only install the 64-bit version of Visual COBOL. The glibc-locale-32bit library is required.
  • ² On Red Hat these libraries are required to enable COBOL to compile.

• Oracle's implementation of Java 7, 8 (32 or 64-bit versions), and Java 9 (64-bit version only), and AdoptOpenJDK's OpenJDK 8 are supported for executing JVM COBOL code, and for native COBOL and Java interoperability. You can download Oracle's Java EE from Oracle's Web site and install it anywhere on your machine. Alternatively, you can download AdoptOpenJDK's OpenJDK 8 with Hotspot from AdoptOpenJDK's Web site and unpack the archive anywhere on your machine.
  Note:

  • On AIX and zLinux, you need to have IBM's JDK. The earliest supported release of IBM's JDK is 7.0 Service Refresh 8. If you install IBM's JDK 8, on AIX you must install its latest fix - JDK 8 SR5 FP16. You can get IBM's AIX JDK from IBM's Web site.
  • On HP-UX, you need to have HP-UX JDK. The earliest supported release of HP-UX is JDK 7.0.11. You can get the HP-UX Java JDK from HP's Web site.
  • On Solaris platforms (both SPARC and Intel) only the 64-bit version of Java 8 and later is supported.

To execute JVM COBOL code, you need to set the environment as follows:

• You need to set the JAVA_HOME environment variable. When installing the product, set this variable to a 64-bit Java installation or the installation terminates. For example, execute the following:

  export JAVA_HOME=java_install_dir

  where java_install_dir is the path to the JAVA installation directory such as /usr/java/javan.n

• You need to add $JAVA_HOME/bin to your system PATH variable. To do this, execute:

  export PATH=$JAVA_HOME/bin:$PATH

• You need to set the LANG environment variable to pick up localized messages. The LANG settings are English and Japanese only.
