Running the new_install utility (for advanced users)

Use the new_install utility that is provided with an instance of IBM® XL C/C++ for Blue Gene®/Q, V12.1 compiler to configure an advanced installation if all compiler packages corresponding to this instance have been installed in the same location, and only one version of GCC is installed on your system.

About this task

The new_install utility performs the following tasks:
  • Backs up any existing configuration file that is located in installation_path/vac/bg/12.1/etc/ vac.cfg.
  • Queries the RPM database for the paths to the compiler packages and the paths to the 32-bit GCC (gcc32path) and the 64-bit GCC (gcc64path) in the PATH environment variable, and then uses the obtained values to run the vac_configure utility.
  • Searches for the Blue Gene/Q tool chain in the default location: /bgsys/drivers/ppcfloor.
  • Installs the license file.
  • Generates the configuration file in the default location installation_path/vac/bg/12.1/etc/ vac.cfg.
Note: installation_path is the installation location of the compiler packages. If the compiler is installed in the default location, installation_path is /opt/ibmcmp/.
Take the following steps to run the new_install utility:
  1. Change to the directory that contains the compiler executable files:
       cd  installation_path/vacpp/bg/12.1/bin/
    where installation_path is the installation location of the compiler packages. If the compiler has been installed to the default location, installation_path is /opt/ibmcmp/.
  2. Run the following command:
      ./new_install
  3. Read the license agreement and licensing information. If you agree to the licensing terms, accept the license agreement and licensing information.
