Prerequisites.
=============
C++11-compliant C++ compiler. GNU C++ compiler (version >= 4.8.1) is recommend.
Non-GNU compilers might not work at the moment.
GNU multiprecision library (http://gmplib.org), version > 4.0.
[Optional] To build CLN documentation texinfo and TeX are necessary.
If you install CLN from git, you also need
git itself (http://git-scm.com), version >= 1.5.0
GNU autoconf (http://www.gnu.org/software/autoconf), version >= 2.63
GNU libtool (http://www.gnu.org/software/libtool), version >= 1.5
GNU automake (http://www.gnu.org/software/automake), version >= 1.11
Installation from a source .tar.bz2 distribution.
================================================
$ ./configure
$ make
$ make check
[ become root if necessary ]
# make install
To build the manual in PDF, HTML, or PostScript formats, use one of
$ make pdf
$ make html
$ make ps
To compile and run CLN's test suite and check whether the library was
compiled correctly you can use
$ make check
The "configure" script can be given a number of options to enable and
disable various features. Most useful ones are:
--prefix=DIR
Install CLN into the directory DIR (default: /usr/local).
--with-gmp
Use GNU multiprecision library (default: yes, if available)
--disable-static
Don't build static version of CLN library. This option is useful if
want to reduce the build time (and you don't need the static library).
For a complete list, run:
$ ./configure --help
Installation from git.
=====================
1. Download the code.
Initial download:
$ git clone git://www.ginac.de/cln.git
Later on you can update your copy with
$ git pull
2. Make sure all required software is installed. This is *really*
important step. If some package is missing, the ‘configure’ script might
be misgenerated,
3. Run
$ ./autogen.sh
to generate the ‘configure’ script, and proceed in a standard way, i.e.
$ ./configure
$ make
[become root if necessary]
# make install
On some platforms (arm, hppa, sparc), problems with the assembler routines
have been reported. It may be best to add "-DNO_ASM" to CPPFLAGS before
configuring:
$ ./configure CPPFLAGS=-DNO_ASM
More detailed installation instructions can be found in the documentation,
in the doc/ directory.
