WIndows+VScode中导入GMP（成功）
windows + vs2019 (最后一步有问题)
ubuntu下安装成功，unbuntu下安装在本文后面
1.先安装cygwin
官网 https://www.cygwin.com/install.html
2. 如果以前安装过cygwin
可进入安装目录执行,比如我这是在D:\cygwin64
setup-x86_64.exe -q -P libgmp-devel -P gcc -P g++ -P make
等待安装结束
3. 下载GMP
https://gmplib.org/download/gmp/gmp-6.2.0.tar.xz
. 4. 打开cygwin终端
将刚下下好gmp压缩包拷贝到要解压路径下,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
这里我没有设置安装路径，提示默认安装路径在 /usr/local，比如我的在D:\cygwin64\usr\local
automake 读取 Makefile.am 来产生 Makefile.in, configure 读取 Makefile.in 来产生 Makefile ,make 使用Makefile
遇到问题
checking for suitable m4... configure: error: No usable m4 in $PATH or /usr/5bin (see config.log for reasons).
解决安装m4
可以通过apt-cyg 安装
apt-cyg install m4
也可以这样
setup-x86_64.exe -q -P m4
ctrl+ F5 添加launch.json，内容如下,可以按照我的模板进行修改。

ctrl + shit + p 添加tasks.json

],

}
添加c_cpp_properties.json

"includePath": [

}
如果cygwin 中没有安装gdb,可以找到cygwin安装包setup-x86_64.exe，在控制台运行
setup-x86_64.exe -q -P gdb
测试结果
后记(unbuntu下配置)
搞了半天导入到VScode下还是有错，ubuntu真香。
sudo apt-get install libgmpxx4ldbl
如果没有装m4
sudo apt-get install m4
到此安装完毕
测试代码
#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;
}
编译命令
g++ testGmp.cpp -o test.o -lgmpxx -lgmp
