2 REM ================================================================
3 REM You can use either GCC (the default) or MSVC to build git
4 REM using the GIT-SDK command line tools.
8 REM GIT-SDK BASH windows inherit environment variables with all of
9 REM the bin/lib/include paths for GCC. It DOES NOT inherit values
10 REM for the corresponding MSVC tools.
12 REM During normal (non-git) Windows development, you launch one
13 REM of the provided "developer command prompts" to set environment
14 REM variables for the MSVC tools.
16 REM Therefore, to allow MSVC command line builds of git from BASH
17 REM and MAKE, we must blend these two different worlds. This script
18 REM attempts to do that.
19 REM ================================================================
20 REM This BAT file starts in a plain (non-developer) command prompt,
21 REM searches for the "best" command prompt setup script, installs
22 REM it into the current CMD process, and exports the various MSVC
23 REM environment variables for use by MAKE.
25 REM The output of this script should be written to a make "include
26 REM file" and referenced by the top-level Makefile.
28 REM See "config.mak.uname" (look for compat/vcbuild/MSVC-DEFS-GEN).
29 REM ================================================================
30 REM The provided command prompts are custom to each VS release and
31 REM filled with lots of internal knowledge (such as Registry settings);
32 REM even their names vary by release, so it is not appropriate for us
33 REM to look inside them. Rather, just run them in a subordinate
34 REM process and extract the settings we need.

37 REM Current (VS2017 and beyond)
38 REM -------------------
39 REM Visual Studio 2017 introduced a new installation layout and
40 REM support for side-by-side installation of multiple versions of
41 REM VS2017. Furthermore, these can all coexist with installations
42 REM of previous versions of VS (which have a completely different
45 REM VS2017 Update 2 introduced a "vswhere.exe" command:
46 REM https://github.com/Microsoft/vswhere

60 REM than "if exist <path>" because of script problems with pathnames
