Linux installation on the host PC
The supported development environment for using the STLinux Distribution is a standard x86 PC running Linux. Two Linux host distributions are supported:
- The Red Hat, Inc commercial product Red Hat Enterprise Linux Workstation (RHELWS). This is available for purchase from Red Hat and their distributors, who also provides paid-for support.
- The free software distribution Fedora. This is available for free download, and although it is sponsored by Red Hat, it is not directly supported by them. However there are several mailing lists which offer community support.
STLinux Distribution release 2.0 is supported on RHELWS version 3 and Fedora Core 4. In addition STLinux Distribution release 2.2 also supports Fedora Core 5. Other host platforms are not officially supported, and if problems are found which relate specifically to the use of a different distribution, we may not be able to support you. However, we do have some experience with the use of other distributions, so listed here are some hints and tips which may prove useful.
The stmyum program is written in python, and
so uses the host's python interpreter and libraries. However
the version of python provided with the various distributions we
support can vary considerably. For this reason a number of RPM packages
are available which provide python libraries which we have found to be
missing on various hosts, and even a replacement version of the
stmyum package for very old python installations.
These are available in the
compat directory on the FTP
server.
These additional packages should only be installed if absolutely required, as they may conflict with the version provided by the host's python installation.
Notes for Specific Host Distributions
Enterprise Linux Work Station 4 (RHELWS4)
The STLinux Distribution has been successfully used on Update #3 of the RHELWS4, that is RHELWS4U3.
Although not known, it is believed that other update releases of RHELWS4 should install directly, with no additional requirements.
Unknown.
Enterprise Linux Work Station 3 (RHELWS3)
Should install directly, with no additional requirements.
The default version of stmyum now used in
STLinux Distribution release 2.2 requires a more up to date version
of python than that shipped with RHEL3. For this reason a couple of additional
packages are required:
- stlinux22-host-python-celementtree
- stlinux22-host-yum-python2.2
These should be downloaded from the
compat directory on the FTP server and installed using the
rpm command. Note that you must be running
as root to do this.
Fedora Core 6
Requires C++ backward compatibility library:
compat-libstdc++-33-3.2.3-61.i386.rpm or
later.
This is not likely to be installed by default, so please ensure this
package is installed prior to installing the STLinux Distribution on
such a machine.
It is required that SELinux is disabled to avoid problems with using the STLinux Distribution. See Notes on SELinux for details.
Fedora Core 5
Requires C++ backward compatibility libraries: compat-libstdc++-33-3.2.3-55.fc5.i386.rpm.
This is not likely to be installed by default, so please ensure this
package is installed prior to installing the STLinux Distribution on
such a machine.
It is required that SELinux is disabled to avoid problems with using the STLinux Distribution. See Notes on SELinux for details.
Fedora Core 4
Requires C++ backward compatibility libraries:
compat-libstdc++-33-3.2.3-47.fc4.i386.rpm.
This is likely to be installed by default if you have done a workstation
install, but may need to be installed manually for a server.
It is recommended that SELinux is disabled to avoid possible problems with the STLinux Distribution. See Notes on SELinux for details.
Fedora Core 3
Requires C++ backward compatibility libraries:
compat-libstdc++-8-3.3.4.2.i386.rpm.
This is likely to be installed by default if you have done a workstation
install, but may need to be installed manually for a server.
It is recommended that SELinux is disabled to avoid possible problems with the STLinux Distribution. See Notes on SELinux for details.
Red Hat 9
In practise the ST40 version of the distribution appears to work correctly, with the updates detailed beneath. However, the ST231 version is known not to work, because of shared library incompatibilities.
The native RPM system itself must be upgraded before the STLinux 2.0
distribution is installed. Version 4.2 contains a serious bug, which is
fixed in 4.2-1.
Install: rpm-4.2-1.i386.rpm.
The C++ backward compatibility libraries must be installed,
in order to install the STLinux 2.0 distribution. This
package may already be installed depending on the type
of RH9 installation you performed.
Install: compat-libstdc++-7.3-2.96.118.i386.rpm.
Notes on SELinux
SELinux is a Security Enhanced version of Linux. This provides additional security auditing and checking on a Linux system. However, this can cause difficulties in the installation and normal use of the STLinux Distribution. STMicroelectronics recommends that SELinux is disabled on machines used for the STLinux Distribution. This is less of a problem with FC3 or FC4. However, with FC5 SELinux does cause problems and we require SELinux to be disabled for correct behaviour.
To check the current SELinux setting, run:
% /usr/sbin/sestatus
To disable SELinux, edit the /etc/selinux/config
file to change it, so that it contains SELINUX=disabled, and re-boot, then
re-run /usr/sbin/sestatus to verify
the status of SELinux.
