Installing packages to multiple, nondefault locations

Use this procedure in highly specialized situations in which you want to install groups of compiler packages to multiple, different locations. For example, you could install all the compiler library packages to one directory, the runtime environment packages to another directory, and so on. However, certain packages must be installed together in the same directory.

About this task

For highly specialized situations only, you might need to install different packages to different locations.

Note: If you want to install packages in different subdirectories, do not install any packages in the /opt/ibm/ or /opt/ibmcmp/ directory.

Table 1 provides information about which packages must be installed together in the same directory and which can be installed in any directory.

Table 1. Rules for installing packages to multiple, nondefault locations
Package Name	Package Description	Rules for installation to a nondefault location
xlsmp.msg.rte	IBM® SMP messages package	All XL SMP packages must be installed in the same location. For the remainder of this document, the name `xlsmprt_path` is used to refer to this location.
xlsmp.rte	IBM SMP runtime package
libxlsmp-devel	IBM SMP static library package
libxlmass-devel	IBM Mathematical Acceleration Subsystem (MASS) package	Any location. For the remainder of this document, the name `xlmass_path` is used to refer to this location.
vacpp.rte	IBM XL C/C++ runtime package	All XL C/C++ runtime packages must be installed in the same location. For the remainder of this document, the name `xlrte_path` is used to refer to this location.
xlc-eval-license¹	IBM XL C/C++ license package for the evaluation copy	Any location. For the remainder of this document, the name `lic_path` is used to refer to this location.
xlc-license²	IBM XL C/C++ license package for XL C/C++ for Linux, V13.1
libxlc-devel	IBM XL C/C++ compiler libraries package	All XL C/C++ compiler and library packages must be installed in the same location. For the remainder of this document, the name `xlcmp_path` is used to refer to this location.
xlc	IBM XL C/C++ compiler package
Notes: Only included in the evaluation copy of the XL C/C++ for Linux compiler. Only included in XL C/C++ for Linux, V13.1. If you are installing a PTF, ignore the xlc-license package.

To install a relocatable RPM package to any location other than the default location, issue the following command for each group of packages you want to install to a nondefault directory:

   rpm -ivh package --prefix  package_installation_path

where package_installation_path is a directory other than /opt/ibm/ or /opt/ibmcmp/, and corresponds to one of the appropriate paths listed in Table 1.
