MPFR library built for Windows using msys2/mingw64

Gmp Windows Build Number

GMP releases starting with 6.0 do not support ‘ABI=32’ on FreeBSD/amd64 prior to release 10.0 of the system. The cause is a broken limits.h, which GMP no longer works around. MS-DOS and MS Windows. On an MS-DOS system DJGPP can be used to build GMP, and on an MS Windows system Cygwin, DJGPP and MINGW can be used. Gmp-4.3.2.tar.bz2 free download. GMP-ECPP Open source implementation of Elliptic Curve Primality Proving algorithm, using just the GMP library. It looks like an out-of-tree build for gmp just won't work for windows/msys2 (at least without some sort of patch for gmp). The configure command that deps/Makefile wants to execute on my machine is.

The GNU Multi-Precision library, or GMP, is an essential component of the programmer who works with mathematics on a regular basis. The problem is, C and C only come with data types with fixed sizes (int, long, double, etc.), which severely limits the. Get notifications on updates for this project. Get the SourceForge newsletter.

Prebuilt packages

The current prebuilt packages can be downloaded from dist/mpfr-3.1.5_gmp-6.1.2.

Note that libgcc is not shipped together with pacakges where libgmp-10.dll and libmpfr-4.dll have it as a runtime dependency. This is because I was so far unable to obtain sources from which were mingw32 and mingw64 toolchains built under msys2. For now you can perhaps use those available directly from the mingw64 project.

For x32 Windows there is libgcc_s_dw2-1.dllhere.
For x64 Windows there is libgcc_s_seh-1.dllhere.

How to build libmpfr-4.dll

0. Example build script

   If you already know what to do, here is an example build/build.sh script. You can adapt it if you like.

1. Install MSYS2 and mingw-w64.

   Follow their instruction manual, once you have setup pacman install required toolchains and other packages:

2. Download GMP and MPFR source code

   Extract the source code folders, for example to c:libs.
   For extracting .lz file you can use tar --lzip -xvf gmp-*.tar.lz.

3. Open the correct shell for the compilation

   This is by default MSYS2 64bit/MinGW 32-bit or MSYS2 64bit/MinGW 64-bit in the Windows startup menu.
   Check your gcc version by gcc -v. Note the compiler and the configuration flags there.

4. Compile gmp and mpfr

   The following example code uses /c/libs/x32 directory just as an example.

   You can read more on what those configure flags do by ./configure --help in respective folders.
   For now it is enough to know that:

   • --enable-shared produces a shared .dll file

   • --disable-static disables compilation of a static library
     This is especially important for gmp, which can not do both static and dynamic compilation at once.

   • --prefix=<path> is where the result is installed after the compilation
     This is set by default to --prefix=/mingw32 or --prefix=/mingw64 based on the shell running.

   • --with-gmp=<path> is how you can specify your custom path to gmp, if you do not use the default one
     I used this option because otherwise configure posted a warning about not matching version of gmp.h.

   Note if you have encountered error: gmp.h isn't a DLL: use --enable-static --disable-shared
   during mpfr compilation, as I have, it is because mingw64 is not picking up any installed gmp dll.

License information

• GNU Compiler Collection (GCC), which libgcc is a part of, is distributed under GNU GPL 3+
  with GCC Runtime Library Exception. The runtime library exception is described in this rationale.
  As a result libraries linked statically to libgcc do not have any license restrictions,
  provided they are elegible to the exception.

• mingw-w64GCC for Windows 64 & 32 bits states that it license is disclosed along with its sources and is permissive.
  This information is well hidden on their webpage in the support section.
  This also applies to winpthread library or libwinpthread-1.dll (not to confuse with POSIX Threads for Windows or pthread-win32).
  In binary distributions of msys2/mingw64 targeting x86 and x64 you can find under mingw32 or mingw64 a file licenses/mingw-w64/COPYING that states:

  With exception of certain parts that are prominently marked as being
  in the Public Domain, BSD, or LGPL this Software is provided under the
  Zope Public License (ZPL) Version 2.1.

  Also of note should be COPYING.MinGW-w64.txt and COPYING.MinGW-w64-runtime.txt where the first also states:

  The idea is that if you create binary packages of your software with MinGW-w64, you can simply copyCOPYING.MinGW-w64-runtime.txt into your package to fulfill the license requirements of the MinGW runtime.

  A separate license notice for winpthread is located in licenses/winpthread/COPYING.
  It seems fairly permissive, though it requires you to copy the notice and mentions having a part of posix-win32:

  Parts of this library are derived by:
  Posix Threads library for Microsoft Windows

• The GNU Multiple Precision Arithmetic Library (GMP) uses dual licensing under GNU LGPL v3 and GNU GPL v2.

• The GNU MPFR Library is licensed under GNU LGLP v3.

  LGLPv3 and GPLv2 impose requirements on source code distribution alongside binary distributions. The safest option is to simply distribute the source code with the provided binary distribution, because any other option usually results in long-term obligations.

  Note that mingw64 distribution also contains licenses/gmp and licenses/mpfr, because mingw64 ships with some version of GMP and MPFR. This shows what license notices must be provided in such case.

  You can read it all for yourself (though check your sanity first).

The packages within the MinGW/Base directory are supported by the MinGWdevelopment team; they provide the core facilities required for a basicMinGW installation.To install files distributed by MinGW we suggest you use the mingw-getinstaller: https://sourceforge.net/projects/mingw/files/InstallerTo set mingw-get up for first time use, run the mingw-get-setup.exetool; this will install mingw-get for use as a command line tool, and,at your option, as a GUI installer tool. Once set up, you may then useit at any time, to install your choice of additional packages.
