在 Cygwin shell 中调用 cl.exe(MSVC 编译器) [英] Invoking cl.exe (MSVC compiler) in Cygwin shell

问题描述

我大量使用 Cygwin(带有 PuTTY shell).但是，在 Cygwin Bash shell 中调用 cl.exe(即 Visual C++ 编译器工具链)非常棘手.在 Bash shell 中运行 vcvars*.bat 显然不起作用.我尝试将 VC++ 的环境变量迁移到 Cygwin，但没那么容易.

I'm heavily using Cygwin (with PuTTY shell). But, it's quite tricky to invoke cl.exe (that is, the Visual C++ compiler toolchain) in the Cygwin Bash shell. Running vcvars*.bat in the Bash shell doesn't work obviously. I tried to migrate VC++'s environment variables to Cygwin, but it's not that easy.

如何在 Cygwin 的 Bash shell 中运行 VC++ 编译器?

How do I run the VC++ compiler in Cygwin's Bash shell?

推荐答案

我通常通过添加

call "%VS80COMNTOOLS%vsvars32.bat" >NUL:

到 c:/cygwin/cygwin.bat.请注意，VS80COMNTOOLS 变量非常有用，因为它为您提供了一种万无一失的 (hm) 方法来定位 vsvars32.bat.

to c:/cygwin/cygwin.bat. Note that the VS80COMNTOOLS variable is extremely useful, since it gives you a foolproof (hm) way of locating vsvars32.bat.

另一种方法是这样，它允许您轻松地在不同的 Studio 版本之间切换:

Another approach is this, which allows you to easily switch between different Studio versions:

function run_with_bat()
{
    batfile=$1; shift
    tmpfile="$TMP/tmp$$.bat"
    echo "@echo off" > $tmpfile
    echo "call "%$batfile%vsvars32.bat" >NUL:" >> $tmpfile
    echo "bash -c "%*"" >> $tmpfile
    cmd /c `cygpath -m "$tmpfile"` "$@"
    status=$?
    rm -f $tmpfile
    return $status
}

function run_vs9()
{
    run_with_bat VS90COMNTOOLS "$@"
}

function run_vs8()
{
    run_with_bat VS80COMNTOOLS "$@"
}

您现在可以:

$ run_vs8 cl
Microsoft (R) 32-bit C/C++ Optimizing Compiler Version 14.00.50727.762 for 80x86
Copyright (C) Microsoft Corporation.  All rights reserved. 

usage: cl [ option... ] filename... [ /link linkoption... ]
$ run_vs9 cl
Microsoft (R) 32-bit C/C++ Optimizing Compiler Version 15.00.21022.08 for 80x86
Copyright (C) Microsoft Corporation.  All rights reserved.

usage: cl [ option... ] filename... [ /link linkoption... ]

注意编译器版本.
