Prerequisites.
=============
ANSI-compliant C++ compiler. GNU C++ compiler (version >= 3.4) is recommend.
Non-GNU compilers might not work at the moment.
GNU multiprecision library (http://gmplib.org), version > 4.0 (older 3.x
versions might work too).
[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 >= 2.59
GNU libtool (http://www.gnu.org/software/libtool), version >= 1.5
GNU automake (http://www.gnu.org/software/automake), version >= 1.8
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
$ autoreconf -iv
to generate the `configure' script, and proceed in a standard way, i.e.
$ ./configure
$ make
[become root if necessary]
# make install
CLN is known to work with:
=========================
- Linux/x86, gcc-3.x, gcc-4.[0-9].x
- Linux/x86_64, gcc-3.[3-4], gcc-4.[0-9].x, clang-2.8
- Linux/ia64, gcc-3.[2-4], gcc-4.[0-4].x
- Linux/arm, gcc-3.[0-3] (*), gcc-4.[0-9].x (*)
- Linux/mips, gcc-3.3, gcc-4.[0-9].x
- Linux/sparc, gcc-3.[1-3], gcc-4.[0-9].x
- Linux/alpha, gcc-3.[0-3], gcc-4.[0-2].x
- Linux/powerpc, gcc-3.[0-3], gcc-4.[0-9].x
- Linux/hppa, gcc-4.2.x (*)
- Solaris 2.4 (sparc), gcc-3.[1-3], gcc-4.[0-2].x (*)
- OSF/1 V4.0 (alpha), gcc-3.1
- Irix 6.5, gcc-3.0
- OS X Leopard (x86), gcc 4.0.1
- Windows/32-bit, MSVC 16.00.30319.01
(*) On these platforms, problems with the assembler routines have been
reported. It may be best to add "-DNO_ASM" to CPPFLAGS before
configuring.
Using gcc-4.9, the "make" step takes about 15 minutes, on an x86_64 / 2 GHz.
If you use g++ from gcc-3.0.4 or older on Sparc, add either "-O", "-O1" or
"-O2 -fno-schedule-insns" to the CXXFLAGS. With full "-O2", g++ miscompiles
the division routines. Do not use gcc-3.0 on Sparc for compiling CLN, it
won't work at all.
More detailed installation instructions can be found in the documentation,
in the doc/ directory.
