MinGW作为一个可靠的64位GCC编译器 [英] MinGW as a reliable 64-bit GCC compiler
问题描述
我担心64位的MinGW编译器的可靠性，作为Visual C ++编译器的替代。
I am worried about the reliability of the MinGW compiler for 64-bit, as an alternative to the Visual C++ compiler.
例如，假设C ++代码构建和在Linux下使用GCC 4.6.2完全运行，相应的MinGW将在64位Windows下生成类似可靠的可执行文件/库吗？
For example, assuming C++ code builds and runs perfectly under Linux using GCC 4.6.2, will the corresponding MinGW produce similarly reliable executables/libraries under 64-bit Windows?
Cygwin在可靠性方面是一个更好的选择？是不是对Visual C ++编译器？
Is Cygwin a better option in terms of reliablity? Is neither to the Visual C++ compiler?
推荐答案
首先，一些误解：
-
MinGW（.org）不提供其运行时的64位版本。 MinGW-w64除了它们的32位CRT。他们还在ARM支持工作。
MinGW(.org) does not provide a 64-bit version of its runtime. MinGW-w64 does, in addition to their 32-bit CRT. They are also working on ARM support. And support various additional APIs (Win32 and others).
Cygwin < - > MinGW-w64：Cygwin没有使用MS CRT（msvcrt.dll） 。它改为在您的Cygwin应用程序和系统的操作系统库（kernel32.dll，ntdll.dll等）之间插入一个POSIX兼容层，即cygwin1.dll。
Cygwin <-> MinGW-w64: Cygwin does not use the MS CRT (msvcrt.dll). It instead inserts a POSIX compatibility layer in between your Cygwin app and the system's OS libraries (kernel32.dll, ntdll.dll, etc.), namely cygwin1.dll.
在问题上...
我发现MinGW-w64编译器非常好，GCC 4.6及以上（实际上，4.5.1及以上）非常有能力为Windows生成良好的64位代码。请记住，MinGW提供与msvcrt.dll基本相同的C API，所以转到msdn.com文档（并确保查看MSVC ++ 2003版本的文档，一些功能与较新的运行时有所不同），不要认为因为它是GCC，glibc文档突然适用于Windows。您的代码必须跨平台。还要注意x64 Windows上的 sizeof（long）！= sizeof（T *）将* nix或x86 Windows代码移植到x64 Windows时常出现错误。
I have found the MinGW-w64 compilers very good, and GCC 4.6 and above (actually, 4.5.1 and above) are very capable of producing good 64-bit code for Windows. Please remember that MinGW provides essentially the same C API as msvcrt.dll, so go to msdn.com for documentation (and be sure to look at the "MSVC++ 2003" version of documentation, some functions differ with the newer runtimes), do not think that because it's GCC, glibc documentation suddenly applies to Windows. Your code will have to be cross-platform. Also note that sizeof(long)!=sizeof(T*) on x64 Windows. A commonly encountered error when porting *nix or x86 Windows code to x64 Windows.
