1@echo off 2rem This script adds the latest available tools to the path for the current 3rem command window. However, most builds of Python will ignore the version 4rem of the tools on PATH and use PlatformToolset instead. Ideally, both sets of 5rem tools should be the same version to avoid potential conflicts. 6rem 7rem To build Python with an earlier toolset, pass "/p:PlatformToolset=v100" (or 8rem 'v110', 'v120' or 'v140') to the build script. 9 10echo Build environments: x86, amd64, x86_amd64 11echo. 12set _ARGS=%* 13if NOT DEFINED _ARGS set _ARGS=x86 14 15if not exist "%ProgramFiles(x86)%\Microsoft Visual Studio\Installer\vswhere.exe" goto :skip_vswhere 16set VSTOOLS= 17for /F "tokens=*" %%i in ('"%ProgramFiles(x86)%\Microsoft Visual Studio\Installer\vswhere.exe" -property installationPath -latest -prerelease -products * -requires Microsoft.VisualStudio.Component.VC.Tools.x86.x64') DO @(set VSTOOLS=%%i\VC\Auxiliary\Build\vcvarsall.bat) 18if not defined VSTOOLS goto :skip_vswhere 19call "%VSTOOLS%" %_ARGS% 20exit /B 0 21 22:skip_vswhere 23if not defined VSTOOLS set VSTOOLS=%VS140COMNTOOLS% 24if not defined VSTOOLS set VSTOOLS=%VS120COMNTOOLS% 25if not defined VSTOOLS set VSTOOLS=%VS110COMNTOOLS% 26if not defined VSTOOLS set VSTOOLS=%VS100COMNTOOLS% 27call "%VSTOOLS%..\..\VC\vcvarsall.bat" %_ARGS% 28
