4 GiNaC requires the CLN library by Bruno Haible, available at

6 You will also need a good C++ compiler adhering to the ANSI standard (we
7 used gcc for development so if you have a different compiler you are on
14 As with any autoconfiguring GNU software, installation is as easy as this:
19 [become root if necessary]
23 - Linux/x86, EGCS-1.1.2 or GCC 2-95.1/2-95.2
25 The "configure" script can be given a number of options to enable and
26 disable various features. For a complete list, type:
30 A few of the more important ones:
32 --prefix=PREFIX install architecture-independent files in PREFIX
33 [defaults to /usr/local]
34 --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
35 [defaults to the value given to --prefix]
36 --disable-shared suppress the creation of a shared version of libginac
38 More detailed installation instructions can be found in the documentation,
39 in the doc/ directory.
41 The time the "make" step takes depends heavily on optimization levels.
42 Large amounts of memory (>128MB) will be required by the compiler,
43 also depending on optimization. To give you a rough idea of what you
44 have to expect the following table may be helpful. It was measured on
45 a P-III/500MHz with "enough" memory:
47 step: | GCC optimization level: | comment:
49 --------------+--------+--------+--------+-------------------------------
50 make | ~4m | ~6m | ~10m | building shared and static lib
51 make check | ~2m | ~2m | ~7m | mostly due to compilation
57 You should use at least CLN V1.0.3, since during the development of
58 GiNaC various bugs have been discovered and fixed in earlier versions.
59 To protect you, the "configure" script checks for a feature that was
60 added in V1.0.3 so it won't continue with earlier versions anyhow.
61 Please install CLN properly on your system before continuing with
