I have followed the instruction on the 'GMP Install Instruction for Windows Platform'. I could build a 32bit version of GMP which can be used for Visual Studio.

Then I installed mingw_w64 and msys on another machine (which is running 64bit Windows) and rerun the commands.

1. GMP Install Instruction for Windows Platform. Currently Core Library (from v1.4) uses GNU Multiple Precision Arithmetic Library as its low level big number package.GMP is a free library for arbitrary precision arithmetic, operating on signed integers, rational numbers, and floating point numbers.
2. Gmp Window Cleaning Inc is located at the address 7351 Sw 15th St in Miami, Florida 33144. They can be contacted via phone at (305) 264-1756 for pricing, hours and directions. Gmp Window Cleaning Inc has an annual sales volume of 501K - 999,999. For maps and directions to Gmp Window Cleaning Inc view the map to the right.

./configure was run without any problem. However, when I run 'make', I got the following.

If I used 'gmake' instead, the following error was shown.

I am not familiar with C++ make. Do I need to specify any flag in order to notify mingw_w64 that I am building for 64bit? Thanks.

For me, gmp was successfully built for x86, and I have had problems building x64. The problem was in the following:

In mpnfib_table.c:

while in gmp.h:

fib_table.c is generated by gen-fix.exe tool, and this tool is generated by make.

So, if one tries to build x64 build after building x86 (like me), it is not enough to run 'make clean' first. Delete all 'gen-*.exe' files in gmp root folder after running 'make clean', this files will be rebuilt properly by make. gmp x64 was successfully build for me after that.

Tested on gmp 6.0.0.

See http://gladman.plushost.co.uk/oldsite/computing/gmp4win.php , and note this paragraph;

GMP cannot, however, provide high performance 64-bit libraries on Windows because its 64-bit assembler code is incompatible with Windows x64 calling conventions. This means that 64-bit GMP libraries on WIndows are very slow when compared with MPIR, which has excellent 64-bit assembler support.

So you either disable assembly with ./configure --disable-assembly or use MPIR.

I have tried the following. The library can be built successfully.

How I built dynamic dll gmp-6.1.2 for windows so that the dll can be linked for a visual studio project.

Setup Environment

• Install 7-Zip
• Install Cygwin, add the following packages to the default installation
  • gcc-core
  • gcc-g++
  • libgcc
  • m4
  • make
  • cmake
  • bash
• Add the following Environment Variable to the User PATH: C:Program Files (x86)Microsoft Visual Studio2017EnterpriseVCToolsMSVC14.15.26726binHostx64x64
  • This is so you can use the lib command. Your lib.exe may be located elsewhere.

Build GMP

• Download the tar.bz2 version from https://gmplib.org/#DOWNLOAD and extract the gmp-6.1.2 folder with 7-zip.
• Launch bash.exe from C:cygwin64bin.
• Change directory to the unzipped gmp-6.1.2 folder. Ex: cd 'A:Codegmp-6.1.2'
• Execute ./configure --disable-static --enable-shared
• Execute make
  • This will create cyggmp-10.dll under A:Codegmp-6.1.2.libs
• Execute make check
• Execute cd ./libs
• Execute lib /machine:i386 /def:cyggmp-10.dll
  • This will generate cyggmp-10.exp and cyggmp-10.lib under A:Codegmp-6.1.2.libs for use with visual studio

You now have everything needed to call gmp from C# code.

You might want to take a look at MPIR. It is a fork of GMP that natively supports Visual Studio.
