Installing packages to multiple, non-default 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, all of these locations must be under the root directory /bgsys/xlcompilers, and 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/ibmcmp/ directory.

Table 1 provides information about which packages must be installed together in the same directory and which can be installed in different directories. Note that although packages might be installed in different directories, all of the these directories must be under the root directory /bgsys/xlcompilers.

Table 1. Rules for installing packages to multiple, non-default locations
Package Name	Package Description	Rules for installation to a non-default location
xlsmp.bg.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.bg.rte	IBM SMP runtime package
xlsmp.bg.lib	IBM SMP static library package
xlmass.bg.lib	IBM Mathematical Acceleration Subsystem (MASS) package	Any location under root directory /bgsys/xlcompilers. For the remainder of this document, the name `xlmass_path` is used to refer to this location.
vacpp.bg.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.
vacpp.bg.rte.lnk	IBM XL C/C++ runtime links package
vac.bg.lic	IBM XL C/C++ license package	Any location under root directory /bgsys/xlcompilers. For the remainder of this document, the name `lic_path` is used to refer to this location.
vac.bg.lib	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.
vac.bg.cmp	IBM XL C/C++ compiler package
vacpp.bg.omp	IBM XL C/C++ OpenMP package
vacpp.bg.lib	IBM XL C/C++ compiler libraries package	Must be installed in the same location as the other compiler and library packages above.
vacpp.bg.cmp	IBM XL C/C++ compiler package
vacpp.bg.help.pdf	IBM XL C/C++ Help pdf documentation package	Any location under root directory /bgsys/xlcompilers (optional). For the remainder of this document, the name `doc_path` is used to refer to this location.
vacpp.bg.man	IBM XL C/C++ compiler man pages	Any location under root directory /bgsys/xlcompilers (optional). For the remainder of this document, the name `manpag_path` is used to refer to this location.
vacpp.bg.samples	IBM XL C/C++ samples package	Any location under root directory /bgsys/xlcompilers (optional). For the remainder of this document, the name `smpls_path` is used to refer to this location.

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 non-default directory:

   rpm -ivh package --prefix  package_installation_path

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