2.3: Unarchiving the RTEMS and GNU Components

Many of the components of the RTEMS release are "tarred, zipped" files and have the .tar.gz or .tgz extension. The GNU zip package is required to unarchives these files on the RTEMS ftp site. If this package is not installed, the source can be found in the files or . It may be restored using a command similar to the following:

tar xvf gzip-1.2.4.tar

OR

sh gzip-1.2.4.shar

This will create a subdirectory gzip-1.2.4 in the current directory. Please examine the files README and INSTALL and follow the instructions provided there.

[Note: The GNU tools follow a standard packaging procedure They will unarchive into a directory based on the package name and version number. For detailed instructions on compilation and installation of the GNU tools, please refer to the instructions for each GNU tool.]

Files which have been "tarred, zipped" (i.e. .tar.gz or .tgz extension) may be unarchived with a command similar to one of the following:

gzcat <file>.tgz | tar xvof -

OR

gunzip -c <file>.tgz | tar xvof -

OR

gtar xzvf <file>.tgz

NOTE: gunzip -c is equivalent to gzcat, while gtar is GNU tar.

Given that the necessary utility programs are installed, any of the above commands will extract the contents of <file>.tar.gz into the current directory. All of the RTEMS components will be extracted into the subdirectory rtems-4.7.99.2. To view the contents of a component without restoring any files, use a command similar to the following:

gzcat <file>.tgz | tar tvf -
