export PATH_HOLD=$PATH && export PATH=/opt/gcc-2.95.3/bin:$PATH &&These instructions save the current PATH and then places GCC-2.95.3 at the head of the path. This is done because Tripwire will not compile with the newer GCC. ln -s make /usr/bin/gmake: The reason we create the gmake symlink is that Tripwire will only install if the symlink is present. It may be safely removed after installation. gmake release: This command creates the Tripwire binaries. cp install.{sh,cfg} .: These are copied to the main Tripwire directory so that the script can be used to install the package. cp policy/*.txt /usr/share/doc/tripwire: This command installs the documentation.
