WIndows+VScode中導入GMP（成功）

windows + vs2019 (最后一步有問題)

ubuntu下安裝成功，unbuntu下安裝在本文后面

1.先安裝cygwin

官網 https://www.cygwin.com/install.html

2. 如果以前安裝過cygwin

可進入安裝目錄執行,比如我這是在D:\cygwin64

setup-x86_64.exe -q -P libgmp-devel -P gcc -P g++ -P make

等待安裝結束

3. 下載GMP

https://gmplib.org/download/gmp/gmp-6.2.0.tar.xz

. 4. 打開cygwin終端

將剛下下好gmp壓縮包拷貝到要解壓路徑下,比如我放在D:\GMP

tar -xvf gmp-6.2.0.tar.xz
cd ./gmp-6.2.0
./configure --disable-static --enable-shared --enable-cxx

make
make check
make install

這里我沒有設置安裝路徑，提示默認安裝路徑在 /usr/local，比如我的在D:\cygwin64\usr\local
automake 讀取 Makefile.am 來產生 Makefile.in, configure 讀取 Makefile.in 來產生 Makefile ,make 使用Makefile

遇到問題

checking for suitable m4... configure: error: No usable m4 in $PATH or /usr/5bin (see config.log for reasons).

解決安裝m4
可以通過apt-cyg 安裝

apt-cyg install m4

也可以這樣

setup-x86_64.exe -q -P m4

ctrl+ F5 添加launch.json，內容如下,可以按照我的模板進行修改。

            ],
            "preLaunchTask": "g++.exe build active file"
        }
    ]
}

ctrl + shit + p 添加tasks.json

{
    "version": "2.0.0",
    "tasks": [
        {
            "type": "shell",
            "label": "shell: g++.exe build active file",
            "command": "D:\\cygwin64\\bin\\g++.exe",
            "args": [
                "-g",
                "${file}",
                "-o",
                "${fileDirname}\\main.out",
                "-lgmpxx",
                "-lgmp"
            ],
            "options": {
                "cwd": "D:\\cygwin64\\bin"
            },
            "problemMatcher": [
                "$gcc"
            ],
            "group": {
                "kind": "build",
                "isDefault": true
            }
        },
        {
            "type": "shell",
            "label": "g++.exe build active file",
            "command": "D:\\cygwin64\\bin\\g++.exe",
            "args": [
                "-g",
                "${file}",
                "-o",
				"${fileDirname}\\main.exe",
				"-lgmpxx",
				"-lgmp"
            ],
            "options": {
                "cwd": "D:\\cygwin64\\bin"
            }
        },
        {
            "type": "shell",
            "label": "g++.exe build active file",
            "command": "D:\\cygwin64\\bin\\g++.exe",
            "args": [
                "-g",
                "${file}",
                "-o",
                "${fileDirname}\\${fileBasenameNoExtension}.exe"
            ],
            "options": {
                "cwd": "D:\\cygwin64\\bin"
            }
        }
    ]
}

添加c_cpp_properties.json

{
    "configurations": [
        {
            "name": "Win32",
            "includePath": [
                "${workspaceFolder}/**",
                "D:\\cygwin64\\usr\\local\\include"
            ],
            "defines": [
                "_DEBUG",
                "UNICODE",
                "_UNICODE"
            ],
            "windowsSdkVersion": "10.0.18362.0",
            "compilerPath": "D:\\cygwin64\\bin\\g++.exe",
            "cStandard": "c11",
            "cppStandard": "c++17",
            "intelliSenseMode": "clang-x64"
        }
    ],
    "version": 4
}

如果cygwin 中沒有安裝gdb,可以找到cygwin安裝包setup-x86_64.exe，在控制台運行

setup-x86_64.exe -q -P gdb

測試結果

后記(unbuntu下配置)

搞了半天導入到VScode下還是有錯，ubuntu真香。

sudo apt-get install libgmpxx4ldbl

如果沒有裝m4

sudo apt-get install m4

到此安裝完畢

測試代碼

#include<gmpxx.h>
#include<iostream>
using namespace std;

int main()
{
    mpz_t x;
    mpz_init(x);
    cin>>x;
    mpz_mul(x,x,x);
    cout<<x<<endl;
    mpz_clear(x);
    return 0;
}

編譯命令

g++ testGmp.cpp -o test.o -lgmpxx -lgmp
