503503If GMP was built with the 64-bit ABI, before building and testing MPFR,
504504you should set the OBJECT_MODE environment variable to 64, e.g., with:

506506 export OBJECT_MODE=64

509- value to the "configure" script: using --with-gmp-build is not sufficient
510- due to the early compiler tests, as gcc will not compile any program if
511- OBJECT_MODE is 64 and the -maix64 option is not provided.

513+ ======================================
516514
517515There are several ways of building MPFR on Windows, the most appropriate
518516approach depending on how you intend to use the resulting libraries.
519517
520518a. Using MinGW
521519==============
522520
523- 1 - We advise to use MinGW (http://www.mingw.org/), which is simpler and
524- less demanding than Cygwin. Contrary to Cygwin, it also provides native
525- Windows code.
521+ 1 - We advise to use MinGW (http://www.mingw.org/ for 32-bit, and
522+ https://sourceforge.net/projects/mingw-w64/ for 32- and 64-bit),
523+ which is simpler and less demanding than Cygwin. Contrary to Cygwin,
524+ it also provides native Windows code.
526525
5275262 - If you just want to make a binary with gcc, there is nothing to do:
528527 GMP, MPFR and the program compile exactly as under Linux.
529- But if you want to generate a library for MinGW from a Cygwin
530- environment, you may need the -mno-cygwin gcc option (otherwise
531- a typical error is _P_WAIT being undeclared).
532-
533- 3 - If you want to make libraries work under another Windows compiler
534- like Visual C / C++, since the unix-like *.a library files are compatible
535- with Windows *.lib files, you can simply rename all *.a libraries to *.lib.
536-
537- With gmp-4.1.3, the only remaining problem seems to be the "alloca" calls
538- in GMP. Configuring GMP and MPFR with --enable-alloca=malloc-reentrant
539- should work (if you build MPFR with GMP internal files).
540-
541- Or you could add the library
542- "$MINGWIN$/lib/gcc-lib/mingw32/$VERSION$/libgcc.a"
543- to your project: it contains all the extra-functions needed by a program
544- compiled by gcc (division of 64-bit integer, bcopy, alloca...).
545- Of course, include it if and only if your compiler is not gcc.
546528
547- 4 - On Windows32 / MinGW, if all the tests fail, try to run the test suite
548- with "make check EXEEXT=".

550- 5 - To avoid using the Microsoft runtime (which might not be conform to ISO C),
529+ 3 - To avoid using the Microsoft runtime (which might not be conform to ISO C),
551530 you can use the MinGW runtime package (which is an integral part of MinGW).
552531 For example, with MinGW versions 3.15 and later you can get an
553532 ISO-compliant printf() if you compile your application with either
554- '-ansi', '-posix' or '-D__USE_MINGW_ANSI_STDIO'. For example, you can
555- compile and test MPFR with CC="gcc -D__USE_MINGW_ANSI_STDIO".
556-
557- For example under Win32, the following problem has been experienced with
558- MPFR 2.4.0 RC1 and the MSVC runtime (msvcrt.dll):
559-
560- Error in mpfr_vsprintf (s, "%.*Zi, %R*e, %Lf%n", ...);
561- expected: "00000010610209857723, -1.2345678875e+07, 0.032258"
562- got: "00000010610209857723, -1.2345678875e+07, -0.000000"
563- FAIL: tsprintf.exe
564-
565- This error is due to the MSVC runtime not supporting the L length modifier
566- for formatted output (e.g. printf with %Lf). You can check this with the
567- following program:
568-
569- #include <stdio.h>
570- int main (void)
571- {
572- long double d = 1. / 31.;
573- printf ("%Lf\n", d);
574- return 0;
575- }
576-
577- The expected output is 0.032258.
578-
579- Note: The L modifier has been standard for a long time (it was added
580- in ISO C89).

625- The MinGW64 version of the GCC compiler is now available here:
626-
627- https://sourceforge.net/projects/mingw-w64/
628-

638-
639- These build projects contain both win32 and x64 builds but the latter
640- can only be built if your version of Visual C++ contains the 64-bit
641- compiler and tools. On Visual C++ 2008, the 64-bit tools are an
642- option during installation so if you don't have them you will need
643- to start the Visual Studio installer and add them to your IDE
644- configuration. On Visual C++ 2010 they are installed by default.
553+ c. Using Microsoft Visual C++ and Intel C++ Compilers
554+ =====================================================

562+ The Intel C++ compiler provided as a part of Intel Parallel Studio XE
563+ can also be used:
653564
654- Visual C++ Express 2010 requires the Windows 7 SDK to be installed
655- in order to build x64 projects. This SDK is available here:
