You first need to install GMP, the GNU Multiprecision Arithmetic Library, 21 see <http://gmplib.org/>, and GNU MPFR, see <http://www.mpfr.org>. 22 GNU MPC requires GMP version 5.0.0 or later 23 and GNU MPFR version 4.1.0 or later. 24 251. In the directory of the GNU MPC archive, type 26 27 tar xzf mpc-1.2.0.tar.gz 28 cd mpc-1.2.0 29 ./configure 30 make 31 32 This assumes that GMP and GNU MPFR are installed in a directory searched 33 by default by the compiler. Otherwise, use --with-gmp=DIR or 34 --with-mpfr=DIR with ./configure (see the Texinfo documentation). 35 362. You should run the test suite, type 37 38 make check 39 40 If any error occurs, please report it on the mailing list 41 <mpc-discuss@lists.gforge.inria.fr>, or file a bug at the bug tracker 42 <https://gforge.inria.fr/tracker/?atid=607&group_id=131&func=browse> . 43 443. To install the GNU MPC library, type 45 46 make install 47 48 By default, the files are copied into subdirectories of /usr/local. 49 You need write permissions on these directories, or pass an alternative 50 installation directory using the --prefix option to ./configure. 51 524. You can optionally create documentation, type 53 54 make dvi 55 56 or 57 58 make ps 59 60 This requires the Texinfo package (version 4.2 at least). 61 62In case of difficulties, please send a description of the problem to 63<mpc-discuss@lists.gforge.inria.fr>. 64 65############################################################################## 66 67Known problems: 68=============== 69 70When LD_LIBRARY_PATH is set to various paths, it might confuse the configure 71script, even with --with-gmp and --with-mpfr options. Then try to unset 72LD_LIBRARY_PATH. 73 74############################################################################## 75 76Note for AIX users: 77=================== 78 79If GMP was built with the 64-bit ABI, before building and testing GNU MPC, 80it might be necessary to set the OBJECT_MODE environment variable to 64 81by, e.g., 82 export OBJECT_MODE=64 83This has been tested with the C compiler IBM XL C/C++ Enterprise Edition 84V8.0 for AIX, version: 08.00.0000.0021, GMP 4.2.4 and GNU MPFR 2.4.1. 85 86############################################################################## 87 88Note for Windows users: 89======================= 90 91There is a special file Makefile.vc for Windows, contributed by Mickaël 92Gastineau. This file works both for the Windows Server 2003 R2 Platform SDK, 93and for the Windows SDK of Vista. To use it, simply replace "make" by 94"nmake /f makefile.vc" in the above instructions: 95 96compilation : 97nmake /f makefile.vc GMP=<gmp_install_dir> MPFR=<mpfr_install_dir> 98 99clean : 100nmake /f makefile.vc GMP=<gmp_install_dir> MPFR=<mpfr_install_dir> clean 101 102check : 103nmake /f makefile.vc GMP=<gmp_install_dir> MPFR=<mpfr_install_dir> check 104 105If you want to compile mpc with mingw in the msys shell, you might need to 106add the following to the configure command (or in your environment): 107 108LDFLAGS=-L/usr/local/lib CPPFLAGS=-I/usr/local/include 109 110In addition, you might need to give the following additional argument to 111configure (reported for mpc-0.9): 112 113CPP="x86_64-w64-mingw32-gcc -E" 114 115(reported by Sisyphus) 116
