Installing Linux applications

After installing the LKP and associated Caldera OpenLinux RPM packages, you might want to install additional Linux applications from other sources. Linux applications are packaged in a variety of formats: RPM packages are the most common, but you might have to run an install or setup program, or extract a cpio or tar archive.

Generally, to install a new Linux application, you should be in Linux mode, and follow the instructions that come with the application. If you don't have instructions, you can usually assume the following:

• If there is an install or setup file, you probably have to run it to install the application. For example, to mount a CD and run an install program from the CD you might issue the following commands:

     /unixware/sbin/mount `/unixware/usr/bin/devattr cdrom1 bdevice` /linux/mnt
     cd /linux/mnt
     ./install
  

• If a file has a .rpm extension it is an RPM package and you can install it using the rpm command. See rpm(8linux).

• If a file has a .cpio extension it is a cpio archive. See cpio(1). A .tar extension indicates a tar archive. See tar(1).

Be aware that some UnixWare 7 tuning might be required before a Linux application can be installed or run. See ``Tuning for Linux applications''.
