Can anyone suggest a multiple precision library that comes with pre-built windows binaries. I need to use it use with an existing Visual Studio 2010 project (or where I can get pre-built binaries for win7 64bit for GMP).

I have tried and failed to compile GMP and MPIR and other projects none of them work with various frustrating and ambiguous errors. Unfortunately time pressures are getting to me and what I need to implement is simple if I can get the library built/downloaded.

I need floating point support so a bigint library is not enough.

Thanks,

  • Have you considered installing the SUA SDK so that make and friends will run? Or, failing that, install mingw, upgrade gcc, and compile gmp/mpir? – moshbear May 14 '12 at 01:32
  • I've tried that, I have mingw installed/upgraded etc still get all sorts of errors about all whole load of pre-processor macros being undefined etc. – user1392800 May 14 '12 at 01:38

http://www.cs.nyu.edu/exact/core/gmp/ has the following package with dlls:

dynamic GMP library and header file for Visual C++: gmp-dynamic-vc-4.1.2.zip

They also have the source project files if you want to try recompiling with a different version at some point.

  • I had seen that, however, I'm a little concerned that it's 4.1.2 and the latest version is 5.0.5? I think 4.1.2 is from around 2002! Those project files are from 2004 and are for much much older versions of visual studio. – user1392800 May 14 '12 at 01:37

Your best bet is MPIR. I've built MPIR and MPFR using VS 2010 so it is possible. My Windows system is down at the moment but here are some notes I made.

  1. Download MPIR, unpack, and rename directory to just be "mpir" - remove any version numbers.

  2. Find and follow the readme file that documents installing VSYASM.

  3. Run "mpir_config.py" with Python 3.x to create the project files.

  4. Change the number of parallel builds to 1.

  5. Select a particular target (say "lib_mpir_k8") and it should build.

MPIR also includes a couple of batch files so you can do a command line build using configure.bat and make.bat. I find it is easier than the GUI builds.

IIRC, to build MPFR, I had to modify some of the Include directories but my notes are a little too cryptic.

The MPIR mailing list is quite helpful, too.
