vcvarsall无法将“ cl”识别为内部或外部

Question

I've been trying to install Boost Libraries for 5 months now, yes very embarrassing, and currently this is the error I run into.

I am running this on Windows 7, 64 bit. Boost 1_59_0.

I used the Visual Studio 2013 x64 Native prompt to go to the boost directory and ran

bootstrap.bat

and then

b2 --toolset=msvc --build-type=complete architecture=x86 address-model=64 stage

However I get the error

'cl' is not recognized as an internal or external command

Following this , I ran

vsvarsall amd64

from

C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC

I went back and tried running b2 again but I got the same error as before.

I searched for "cl.exe" on my laptop and I found it here:

C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\bin

C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\bin\x86_amd64

C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\bin\x86_arm

C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\bin\amd64

C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\bin\amd64_arm

C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\bin\amd64_x86

C:\Program Files (x86)\Microsoft Visual Studio 11.0\VC\bin

C:\Program Files (x86)\Microsoft Visual Studio 11.0\VC\bin\x86_amd64

C:\Program Files (x86)\Microsoft Visual Studio 11.0\VC\bin\x86_arm

C:\Program Files (x86)\Microsoft Visual Studio 8\VC\bin

I understand that 'b2' is unable to find 'cl' and I have to give the 'path' to the 'cl.exe' but I don't know how to set path, what to type where etc. I thought that 'vsvarsall' was supposed to fix this but it didn't.

Please help.

EDIT 1:

I set path following the instructions given in the comments, but I am still getting the same errors.

Answer 1

In your log, you have a number of calls to "C:\\Users....\\b2_msvc_12.0_vcvarsall_amd64.cmd". This is a file that caches the environment that VC needs. Could you try deleting it, in case it got stale value from older version?

Answer 2

You need to make sure that you run vsvarsall.bat and in the same cmd window run bootstrap and b2. Since the env variables are only set for that shell. Otherwise add the paths set by vsvarsall.bat manually in environment variables for the system.

You can search your control panel to find where to set environment variables, or hit the windows key and type in environment variables. You will get a shortcut to the window for those settings.
