3.2. ia64 Architectures
- Bugzilla #163910
- In this update, the 64-bit Intel Itanium2 architecture includes runtime support for 32-bit applications through the use of Intel's IA-32 Execution Layer.The IA-32 Execution Layer is provided on the Extras disc for the Intel Itanium2 architecture. In addition, a set of 32-bit libraries and applications are provided on a separate 32-bit Compatibility Layer disc. The IA-32 Execution Layer and 32-bit compatibility packages together provide a runtime environment for 32-bit applications on the 64-bit native distribution.To install the IA-32 Execution Layer and required 32-bit compatibility packages, follow these steps:
- Install Red Hat Enterprise Linux 4.8 for the Intel Itanium2 Architecture.
- Insert the Red Hat Enterprise Linux 4 Extras CD, which contains the
ia32elpackage. - After the system has mounted the CD, change to the directory containing the Extras packages. For example:
cd /media/cdrom/RedHat/RPMS/ - Install the
ia32elandkshpackages:rpm -Uvh ia32el-<version>.ia64.rpm ksh-<version>.ia64.rpmwhere <version> is the respective versions of theia32elandkshpackages to be installed. - Eject the Extras CD:
eject /media/cdrom - To verify the installation of the 32-bit compatibility layer and libraries after installation, confirm if the
/emuldirectory exists and contains files. - To verify that the 32-bit compatibility mode is in effect, type the following in a shell prompt:
service ia32el status - At this point you can install compatibility libraries by inserting the 32-bit Compatibility Layer disc. You may choose to install all of the packages available on the disc or choose the particular packages required in order to provide runtime support for your 32-bit applications.
