Host PC requirements

The SPEAr Linux Support Package (LSP2.3) for SPEAr family has been qualified on Fedora

Core 11 Linux. Using the SPEAr software with other Linux distributions or older Fedora

versions is feasible, but it could require additional preliminary activities, so it is not

recommended.

Please note that the SELinux option has to be disabled.

The stmyum tool

Yum is an automatic updater and package installer/remover for RPM Linux host systems

(like Fedora). It automatically computes dependencies and figures out what things should

occur to install packages. Yum has a number of advantages over using RPM directly, such

as:

●

Automatic updates of installed packages

●

Automatic checks for newly available and updated packages

●

Automatic installation of all the dependency packages for each new package installed

installation of groups of packages as a single unit

●

Increased security as all packages are signed.

The SPEAr Linux Support Package (LSP2.3) relies on a slightly customized version of yum,

known as stmyum, to ensure that it does not interfere with any native yum installation.

It is automatically installed under the path /opt/STM/STLinux-X.X/host/bin. The PATH

environment variable must include this directory to be able to use it.
