Install GMP
Xu Liu
1 Install GMP
1.1 What is GMP
- The GNP Multi-Precision library, shortting for GMP
- A manu for GMP
1.2 Where is GMP
- Download gmp from https://gmplib.org/#DOWNLOAD. you can choose “gmp-6.1.2.tar.bz2”.
- Unzip it into D:\gmp
1.3 On Windows
1.3.1 Install “MinGW” and “MSYS”
- Here is an instruction for installation
- Download MinGW for GNU C/C++ compiler on Windows
- MinGW: Minimalist GNU for Windows
- Install (say “D:\mingw”)
- Choose the first, the second and the last components
- Download MSYS
- MSYS: Minimal SYStem, which is sub-system of MinGW, and it is a bash running on Windows
- Install it to same Path (say D:\mingw)
- Choose Y in the first option
- Choose the same path of MinGW (say D:\mingw) in the second option
- Using MinGW conbining MSYS, one can create both terminal and GNU compiler OS on Windows, which mimicks Linux OS
1.3.2 Install gmp
- Installing
- Click msys and type (waite long time)
- If enable C++
- make
- After done, you can see “libgmp.dll.a” and so on in sub-directory “.libs”
- If error says “can not find libgmp-10.dll”, copy it (locate in “path\gmp.libs”) into “C:/Windows64” or “C:/Windows32” depending your system platform
- Add below header in your C files
- Or
- add this in your C++ files
- Such as
1.3.3 Setup your environment
1.4 On Mac (Linux)
1.4.1 Install gmp
- Download gmp from https://gmplib.org/#DOWNLOAD. you can choose “gmp-6.1.2.tar.bz2”.
- Unzip it
- Click terminal and type
- Or type
- Installing
- Go to gmp-6.1.2
- config
- If enable C++
- make
- After done, you can see “libgmp.dll.a” and so on in sub-directory “.libs”
- Add #include <gmp.h> in your C files
- Or add #include <gmpxx.h> in your C++ files
- Such as
1.4.2 Setup your environment for GCC
- Default lib is “/usr/local/lib” and “/usr/local/incude”
- Do not need setup environment if not specifying a Path in “./configure”
1.5 On Ubuntu
1.5.1 Install gmp
- Similar to on Mac (say 1.2 On Mac)
- You may need install “m4”
- Install m4
- The default path “./configure” is “/usr/local”, which is same as MacOS
- But Ubuntu search default path is “/usr/lib”
- You can set path
1.5.1 Setup your environment for GCC
2 Setting Compiler
2.1 VS2010 On Windows
- Setting VS2010
- Right click your project (say “project_1”), click “Properties”
- Setting “C/C++ General”, add “D:\GMP\gmp6.1.2”
- Setting “Linkage General”, add “D:\GMP\gmp6.1.2\.libs;%(AdditionalLibraryDirectories)”
- Setting “Linkage Input”, add “libgmp.dll.a”
- Setting “C/C++ General”, add “D:\GMP\gmp6.1.2”
2.2 Xcode on Mac/Ubunto
- Setting Xcode on “Build Settings”
- Click your project (say “project_1”), click “Build Settings”
- setting “Other Linkage Flags” to be “-lgmp”
- Setting “Header Search Paths” to be “/usr/local/include”
- Setting “Library Search Paths” to be “/usr/local/lib”
- setting above
3 GCC compiling
- Compile C/C++ file to an executable file on different platforms
- All platforms are similar if your gcc environment is set correctly, except for the arguments order.
- It only depends on gcc/g++
- It is simple for foo.c including gmp.h
- Or for foo.cpp including gmpxx.h
- An example to calculate in add.c
- add.c
#include <iostream>
#include <stdlib.h>
#include <math.h>
#include <gmp.h>
#include <string.h>
using namespace std;
void example(){
mpz_t a,b,c;
mpz_init(a);
mpz_init(b);
mpz_init(c);
mpz_set_str(a,"342312532453246435457",10);
mpz_set_str(b,"346534643743565654456",10);
mpz_add(c,a,b);// c = a + b;
gmp_printf("%Zd\n",c);
mpz_clear(a);
mpz_clear(b);
mpz_clear(c);
}
int main(int argc, char * argv[]){
example();
return 0;
}- Compile on Mac, and then get “add.exe”
- Compile on Linux. I run this on HPCC of MSU, in which the gmp has been installed.
4 Compile on VS 2010
- Produce an executable file foo.exe by VS 2010. Other compiler should be the same
- Setting the first argument to be \(n\), which is passed from outside of foo.exe (say “PI.exe”)
- The executable file can be found in the sub-directory “Debug” of your project
- Setting VS2010
- Right click your project (say “project_1”), click “Properties”
- Click “Debugging” on “Configuration Properties”
- Put an initial value in “Command Arguments”, eg. 1000
- An example
