如何在 Windows 上为 Dev-C++ 安装 C++ 库 [英] How to Install a C++ library on Windows for Dev-C++

问题描述

我下载了一个名为 GMP 的库(用于对任意大数进行计算)，但我不知道如何实际安装和使用它.我找到的所有指令都告诉我运行文件 configure、MakeFile 和 install，但是当我尝试这样做时，我得到 'install' 不是可识别的内部或外部命令.

I downloaded a library called GMP (it's for doing calculations with arbitrarily large numbers) and I can't figure out how to actually install and use it. All of the instructions I find tell me to run the files configure, MakeFile, and install, but when I try to do that I get 'install' is not a recognized internal or external command.

我所能想到的就是这些说明适用于 Linux，但我运行的是 Windows.我在这里找到了一些关于 SO 的说明，告诉我将某些文件复制到 Dev-C++ 文件夹中，但我找不到指定的文件.我以前从来没有安装过这样的库，所以我真的迷路了.f

All I can figure is that the instructions are for Linux, but I'm running Windows. I found a couple of instructions here on SO that tell me to copy certain files into the Dev-C++ folder, but I can't find the files specified. I've never had to install a library like this before, so I'm really lost.f

推荐答案

如果你有最新版本的 Dev-C++，附带 MinGW-w64(作为它的原生环境)，那么你可以下载 GMP 的预构建包来自 此处.之后你所要做的就是:

If you have latest version of Dev-C++, that ships with MinGW-w64 (as its native environment), then you may download pre-builded package of GMP from here. After that all you have to do is:

1. 创建简单的 C++ 控制台项目.

这是一些基本的main.cpp文件:

#include <cstdio>
#include <gmp.h>

int main(int argc, char** argv) {
    mpz_t n;

    mpz_init_set_str(n, "1234567890", 0);

    gmp_printf("%Zd\n", n);

    mpz_clear(n);

    return 0;
}

1. 解压存档
2. 将 gmp.h 头复制到 Dev-Cpp\MinGW64\x86_64-w64-mingw32\include
3. 将libgmp.dll.a复制到MinGW64\x86_64-w64-mingw32\lib
4. 将libgmp-10.dll 共享库复制到Dev-Cpp\MinGW64\bin
5. 编辑项目的属性，将 -lgmp 标志添加到链接器(查找参数选项卡)
6. 编译&运行

1. Unpack archive
2. Copy gmp.h header into Dev-Cpp\MinGW64\x86_64-w64-mingw32\include
3. Copy libgmp.dll.a into MinGW64\x86_64-w64-mingw32\lib
4. Copy libgmp-10.dll shared library into Dev-Cpp\MinGW64\bin
5. Edit properties of your project, add -lgmp flag into Linker (look for Parameters tab)
6. Compile & Run

如果你想要其他版本或者C++接口，那么你需要找到现有的build或者尝试在MinGW环境下编译.

If you want other version or C++ interface, then you need to find existing build or try to compile it under MinGW environment.
