In order to install GiNaC on your system, some prerequisites need to be met. First of all, you need to have a C++-compiler adhering to the ANSI-standard ISO/IEC 14882:1998(E). We used GCC for development so if you have a different compiler you are on your own. For the configuration to succeed you need a Posix compliant shell installed in /bin/sh, GNU bash is fine. The pkg-config utility is required for the configuration, it can be downloaded from http://pkg-config.freedesktop.org. Last but not least, the CLN library is used extensively and needs to be installed on your system. Please get it from ftp://ftpthep.physik.uni-mainz.de/pub/gnu/ (it is covered by GPL) and install it prior to trying to install GiNaC. The configure script checks if it can find it and if it cannot it will refuse to continue.
