| 3 | +REM You can use either GCC (the default) or MSVC to build git |
| 4 | +REM using the GIT-SDK command line tools. |
| 5 | +REM $ make |
| 6 | +REM $ make MSVC=1 |
| 7 | +REM |
| 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. |
| 11 | +REM |
| 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. |
| 15 | +REM |
| 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" commmand 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. |
| 24 | +REM |
| 25 | +REM The output of this script should be written to a make "include |
| 26 | +REM file" and referenced by the top-level Makefile. |
| 27 | +REM |
| 28 | +REM See "config.mak.uname" (look for GIT-MSVC-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 |
| 43 | +REM layout on disk). |
| 44 | +REM |
| 45 | +REM VS2017 Update 2 introduced a "vswhere.exe" command: |
