Prerequisites ============= GiNaC requires the CLN library by Bruno Haible, available at or . You will also need a good C++ compiler adhering to the ANSI standard (we used gcc for development so if you have a different compiler you are on your own). Installation ============ As with any autoconfiguring GNU software, installation is as easy as this: $ ./configure $ make $ make check [become root if necessary] $ make install Known to work with: - Linux/x86, EGCS-1.1.2 or GCC 2-95.1/2-95.2 The "configure" script can be given a number of options to enable and disable various features. For a complete list, type: $ ./configure --help A few of the more important ones: --prefix=PREFIX install architecture-independent files in PREFIX [defaults to /usr/local] --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX [defaults to the value given to --prefix] --disable-shared suppress the creation of a shared version of libginac More detailed installation instructions can be found in the documentation, in the doc/ directory. The time the "make" step takes depends heavily on optimization levels. Large amounts of memory (>128MB) will be required by the compiler, also depending on optimization. To give you a rough idea of what you have to expect the following table may be helpful. It was measured on a P-III/500MHz with "enough" memory: step: | GCC optimization level: | comment: | -O0 | -O1 | -O2 | --------------+--------+--------+--------+------------------------------- make | ~4m | ~6m | ~10m | building shared and static lib make check | ~2m | ~2m | ~7m | mostly due to compilation Problems with CLN ================= You should use at least CLN V1.0.3, since during the development of GiNaC various bugs have been discovered and fixed in earlier versions. To protect you, the "configure" script checks for a feature that was added in V1.0.3 so it won't continue with earlier versions anyhow. Please install CLN properly on your system before continuing with GiNaC.
