9GNU MPC is a complex floating-point library with exact rounding.
10It is based on the GNU MPFR floating-point library (http://www.mpfr.org/),
11which is itself based on the GNU MP library (http://gmplib.org/).

14 Installing GNU MPC
15 ==================
16
17This is for the impatient, for deeper explanations see the chapter
18"Installing GNU MPC" in the Texinfo documentation (type 'info mpc.info').
19
200. 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-1.3.1.tar.gz
28 cd mpc-1.3.1
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@inria.fr>.
42
433. To install the GNU MPC library, type
44
45 make install
46
47 By default, the files are copied into subdirectories of /usr/local.
48 You need write permissions on these directories, or pass an alternative
49 installation directory using the --prefix option to ./configure.
50
514. You can optionally create documentation, type
52
53 make dvi
54
55 or
56
57 make ps
58
59 This requires the Texinfo package (version 4.2 at least).
60
61In case of difficulties, please send a description of the problem to
62<mpc-discuss@inria.fr>.

66Known problems:
67===============
68
69When LD_LIBRARY_PATH is set to various paths, it might confuse the configure
70script, even with --with-gmp and --with-mpfr options. Then try to unset
71LD_LIBRARY_PATH.
72
73##############################################################################
74
75Note for AIX users:
76===================
77
78If GMP was built with the 64-bit ABI, before building and testing GNU MPC,
79it might be necessary to set the OBJECT_MODE environment variable to 64
80by, e.g.,
81 export OBJECT_MODE=64
82This has been tested with the C compiler IBM XL C/C++ Enterprise Edition
83V8.0 for AIX, version: 08.00.0000.0021, GMP 4.2.4 and GNU MPFR 2.4.1.

86
87Note for Windows users:
88=======================
89
90If you want to compile mpc with mingw in the msys shell, you might need to
91add the following to the configure command (or in your environment):
92
93LDFLAGS=-L/usr/local/lib CPPFLAGS=-I/usr/local/include
94
95In addition, you might need to give the following additional argument to
96configure (reported for mpc-0.9):
97
98CPP="x86_64-w64-mingw32-gcc -E"
