The linux version of erc32ccs is compiled on slakware linux using libc5 libraries. Unfortunately, RedHat linux and some versions of Debian might contain outdated libc5 libraries which causes the compiler to fail. The file libc5.tar.gz contains libc5 libraries that should work with erc32ccs. To install them on a Redhat system, do as follows: cd /usr/i486-linux-libc5/lib tar xzvf redhat-libc5.tar.gz /sbin/ldconfig -v Report problems to jgais@ws.estec.esa.nl Jiri Gaisler - ESA/ESTEC
