I'm heavily using Cygwin (with Putty shell). But, it's quite tricky to invoke cl.exe (i.e., 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.
Is there anyone who ever tried to run VC++ compiler in Cygwin bash shell?
Thanks, JJ
I understand that your problem is converting vcvars32.bat into a shell script.
One way around the problem is based on the idea that environment variables are inherited when one process launches another. So you can simply run vcvars32 under cmd and then run bash. This works fine on my machine:
sh-3.2$ 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... ]
Alternatively, run set before and after invoking vcvars32 under cmd, and then create a shell script to set the environment variables.
Another alternative is to open up vcvars32.bat (or vsvars32.bat, which does the real work in recent version of Visual Studio), look at what it does, and replicate that in the appropriate shell script.
It's not particularly complex - all it does is set a bunch of environment variables.
hi,
i have converted my vsvars32.bat file with my visual_studio.env file. when i need to use the command line visual studio's environment i just do a source of this file.
in the sh shell environment i cannot register windows path (\ and ; clash with sh) so before i translate them with cygpath -au or cygpath -aup commands then i write down them into my .env file and traslate back them with cygpath -aw or cygpath -aup commands.
my visual_studio.env file look like this:
VS80COMNTOOLS=$(cygpath -aw '/cygdrive/c/Programmi/Microsoft Visual Studio 8/Common7/Tools/'); export VS80COMNTOOLS
VSINSTALLDIR=$(cygpath -aw '/cygdrive/c/Programmi/Microsoft Visual Studio 8'); export VSINSTALLDIR
VCINSTALLDIR=$(cygpath -aw '/cygdrive/c/Programmi/Microsoft Visual Studio 8/VC'); export VCINSTALLDIR
FrameworkDir=$(cygpath -aw '/cygdrive/c/WINDOWS/Microsoft.NET/Framework'); export FrameworkDir
FrameworkVersion='v2.0.50727'; export FrameworkVersion
FrameworkSDKDir=$(cygpath -aw '/cygdrive/c/Programmi/Microsoft Visual Studio 8/SDK/v2.0'); export FrameworkSDKDir
echo Setting environment for using Microsoft Visual Studio 2005 x86 tools.
DevEnvDir=$(cygpath -aw '/cygdrive/c/Programmi/Microsoft Visual Studio 8/Common7/IDE'); export DevEnvDir
PATH='/cygdrive/c/Programmi/Microsoft Visual Studio 8/Common7/IDE:/cygdrive/c/Programmi/Microsoft Visual Studio 8/VC/BIN:/cygdrive/c/Programmi/Microsoft Visual Studio 8/Common7/Tools:/cygdrive/c/Programmi/Microsoft Visual Studio 8/Common7/Tools/bin:/cygdrive/c/Programmi/Microsoft Visual Studio 8/VC/PlatformSDK/bin:/cygdrive/c/Programmi/Microsoft Visual Studio 8/SDK/v2.0/bin:/cygdrive/c/WINDOWS/Microsoft.NET/Framework/v2.0.50727:/cygdrive/c/Programmi/Microsoft Visual Studio 8/VC/VCPackages':$PATH
INCLUDE=$(cygpath -awp '/cygdrive/c/Programmi/Microsoft Visual Studio 8/VC/ATLMFC/INCLUDE:/cygdrive/c/Programmi/Microsoft Visual Studio 8/VC/INCLUDE:/cygdrive/c/Programmi/Microsoft Visual Studio 8/VC/PlatformSDK/include:/cygdrive/c/Programmi/Microsoft Visual Studio 8/SDK/v2.0/include'); export INCLUDE
LIB=$(cygpath -awp '/cygdrive/c/Programmi/Microsoft Visual Studio 8/VC/ATLMFC/LIB:/cygdrive/c/Programmi/Microsoft Visual Studio 8/VC/LIB:/cygdrive/c/Programmi/Microsoft Visual Studio 8/VC/PlatformSDK/lib:/cygdrive/c/Programmi/Microsoft Visual Studio 8/SDK/v2.0/lib'); export LIB
LIBPATH=$(cygpath -awp '/cygdrive/c/WINDOWS/Microsoft.NET/Framework/v2.0.50727:/cygdrive/c/Programmi/Microsoft Visual Studio 8/VC/ATLMFC/LIB'); export LIBPATH
I hope this can help you
I usually solve this by adding
call "%VS80COMNTOOLS%vsvars32.bat" >NUL:
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.
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 "$@"
}
You can now do:
$ 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... ]
Note the compiler version.
I couldn't add comments to Diomidis's reply :(, so had to post an answer instead. I agree with his answer, but it would be tedious to do "open a command prompt" run vs/vcvars32.bat and the run bash. If you dont bother about cluttering you environment, the best alternative is to modify Cygwin.bat and modify it to look something like this:
@echo off D: chdir D:\cygwin\bin "%VS71COMNTOOLS%\vsvars32.bat" && bash --login -i
Substitute the environment variable VS71COMNTOOLS with something appropriate on your machine.
No need to open command prompt and run bash manually. I like this solution a lot :). I couldnt give credits to the real author of this hack, as I couldnt find a link back to his article, sorry about that!
For me, the following in .bash_profile worked:
"`cygpath -ua "$VS80COMNTOOLS/vsvars32.bat"`" > NUL
Following suggestions in the other answers, I did a diff of my bash "set" results with and without the MSVC variables, and came up with the following script to reproduce them for my installation of Microsoft Visual C++ 2010 Express. I've refactored it a bit to put all the installation-dependent pieces at the top, so hopefully this can be of use to others.

export Framework35Version=v3.5
