Cygwin上的C编译器生成什么？ [英] What do the C compilers on Cygwin generate?

问题描述

根据下面的identify-compilers.sh脚本的输出，看起来Cygwin上提供了以下C编译器。

Based on the output of the identify-compilers.sh script below, it appears that the following C compilers are available on Cygwin. Those labeled "Cygwin" require the cygwin1.dll file to be available.

pc和w64编译器有什么区别？

What is the difference between the "pc" and "w64" compilers?

为什么没有x86_64-pc-mingw-gcc.exe可执行文件？

Why is there no x86_64-pc-mingw-gcc.exe executabe?

有没有其他C编译器可用？ p>

Are there any other C compilers available?

/usr/bin/gcc.exe                        64-bit  Cygwin
/usr/bin/i686-pc-cygwin-gcc.exe         32-bit  Cygwin
/usr/bin/i686-pc-mingw32-gcc.exe        32-bit
/usr/bin/i686-w64-mingw32-gcc.exe       32-bit
/usr/bin/x86_64-pc-cygwin-gcc.exe       64-bit  Cygwin
/usr/bin/x86_64-w64-mingw32-gcc.exe     64-bit

$ cat identify-compilers.sh
#!/bin/bash
for c in $(ls -1 /usr/bin/*gcc.exe); do
    echo === compiler: $c
    $c -o hello.exe hello.c
    objdump -p hello.exe | grep -i "cygwin"
    objdump -p hello.exe | grep -i "64$"
    rm hello.exe
done

推荐答案

1. gcc 只是一个硬链接到 x86_64-pc-cygwin -gcc

x86_64-pc-cygwin-gcc c $ c> i686-pc-cygwin-gcc 就像你说的
Cygwin编译器，也就是说编译器创建的程序依赖
在 cygwin1.dll

x86_64-pc-cygwin-gcc and i686-pc-cygwin-gcc are as you have said the Cygwin compilers, that is to say the compilers that create programs that rely on cygwin1.dll

x86_64-w64-mingw32-gcc 和 i686-w64-mingw32-gcc 是编译器提供
的 Mingw-w64项目

i686-pc-mingw32-gcc 由 MinGW项目提供的编译器

你可能会想，为什么两个Mingw项目？那么Mingw-w64项目是
，因为MinGW 拒绝采用 64位编译器。在此
和 MSYS2项目的开始之前，我认为MinGW项目
已过时。

You may be wondering, why the two Mingw projects? Well the Mingw-w64 project was started because MinGW refused to adopt the 64-bit compiler. Between this and the starting of the MSYS2 project, I consider the MinGW project obsolete.
