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 V1.0.2, since all earlier ones are
somewhat buggy. Even V1.0.1 has a few problems and GiNaC will not
support older versions. Please install it properly on your system
before continuing with GiNaC.
