Clang Integration for Visual Studio, stand-alone

Users of VS2017 (and later) should try the Visual Studio extension LLVM Compiler Toolchain. It is more configurable, contains some bug-fixes and is supported by LLVM.

Users of VS2015 and earlier, or who want to compile with LLVM/Clang using the older toolsets, can try this implementation. Or try extracting the new implementation, see a solution by CFSworks at stackoverflow

This is an reimplementation of the legacy integration method, as used by the LLVM installer up to v6.0.1. Originally created to test an update for the LLVM/Clang integration, adding support for Visual Studio 2017.

This adds LLVM toolset configurations for any installed legacy toolsets since VS2010 (including the Windows XP toolsets). Allowing building these toolset with the targeted version of LLVM/Clang.

Target: Clang for Windows, stable release v6.0.1

Expected to work with:
Visual Studio versions: VS2010, VS2013, VS2015 and VS2017.
Visual C++ Build Tools: 2017 and 2015.

Instructions

Installation

1. Extract all files in an empty directory.
2. Run install.bat. As Administrator when needed. The script requires write access to the MSBuild and VS2017 install directories. Note: Currently the install script stops on the first error.

Removal

1. Run the supplied uninstall.bat (as Administrator, when needed.)
2. (For LLVM v6.01 and earlier) Restore the original configuration. {LLVM install dir.}\tools\msbuild\install.bat

Changes

• install.bat / uninstall.bat
  • Total rewrite, to support user defined install locations for VS2017 Using the Visual Studio Locator Tool
  • Accepting other platform types, when defined, based on directory structure.
  • Only installing toolsets when the base MSVC toolset is installed.
  • Apply redefined install method for older versions. (Needs more testing.)
  • Use pushd and popd to switch the working directory back when the script finishes.
  • On a copy error, try for the next VS installation. This allows for installs and updates without admin rights. E.g. when VS2017 is installed on a users' personal drive.
  • Combined the install and uninstall script. Reducing code duplication, from the shared path generation.
  • Improved progress reporting.
• *.props files
  • Add vs2017 versions.
  • Fixed LibraryPath version number.
• *.targets files
  • Add vs2017 versions.
  • For toolset versions 140(_xp) and 141_(xp), inherit from the Microsoft supplied configuration, to stay up to date. (As the *.props do.)
  • Note: no changes have been made to the files for older compilers. These have been included for proper operation of the install script.
