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.
