如何在 MSYS2 中构建 GMP？

Question

我想在 windows 上使用 GMP，我需要构建静态程序。（这意味着，如果有人能提供另一种使用 libgmp 编译 win32 x86_64 程序的解决方案，我也将不胜感激。）

现在我安装了msys2，并在其中执行了

pacman -S base-devel gcc

然后我从 gmplib.org 下载了 gmp-6.2.0.tar.lz 并将其解压到某个地方，比如

C:\Users\xxx\gmp-6.2.0

然后我用msys2 mingw64进入这个目录执行

./configure
make
make check
make install

前两个命令似乎没问题，输出似乎是正确的。但是， make check 并没有告诉我 make 是否正确。在其输出的末尾，它说，

make[5]: Leaving directory '/c/Users/Fred/gmp-6.2.0/tests/cxx'
make[4]: Leaving directory '/c/Users/Fred/gmp-6.2.0/tests/cxx'

make[2]: Leaving directory '/c/Users/Fred/gmp-6.2.0'
make[1]: Leaving directory '/c/Users/Fred/gmp-6.2.0'

并且 make install 以类似的消息结束。最后，当我尝试编译程序时，它说，

/usr/lib/gcc/x86_64-pc-msys/9.3.0/../../../../x86_64-pc-msys/bin/ld: cannot find -lgmp

事实上，我不是专业的程序员，所以我不太清楚如何安装GMP 对于 mingw。如果有人能告诉我如何从头开始，我将不胜感激。

在@HolyBlackCat的帮助下，我解决了这个问题并成功编译了我的程序。过程如下：

安装 msys2

从msys2.org下载可执行文件并安装msys2。您将在打开的菜单中获得三个快捷方式：MSYS MinGW 32 位、MSYS2 MinGW 64 位和 MSYS2 MSYS。它们之间的区别在于 PATH。 MSYS的路径是/usr/bin，而MinGW 64-bit的路径包括/mingw64/bin.
安装必要的软件包。运行以下命令：

$ pacman -Syu
$ pacman -S mingw-w64-x86_64-gcc mingw-w64-x86_64-gmp

编译你的程序

打开 MSYS2 MinGW 64 位
使用x86_64-w64-mingw32-gcc而不是gcc来编译。（如果没有安装gcc，直接用gcc编译即可。）如果使用其他shell，使用全路径/mingw64/bin/x86_64-w64-mingw32-gcc

如果你需要使用autoconf工具，你可以安装它们

$ pacman -S base-devel
