The Steps to Build Git with VS2015 or VS2017 from the command line.
|
|
|
|
1. Install the "vcpkg" open source package manager and build essential
|
|
third-party libraries. The steps for this have been captured in a
|
|
set of convenience scripts. These can be run from a stock Command
|
|
Prompt or from an SDK bash window:
|
|
|
|
$ cd <repo_root>
|
|
$ ./compat/vcbuild/vcpkg_install.bat
|
|
|
|
The vcpkg tools and all of the third-party sources will be installed
|
|
in this folder:
|
|
<repo_root>/compat/vcbuild/vcpkg/
|
|
|
|
A file will be created with a set of Makefile macros pointing to a
|
|
unified "include", "lib", and "bin" directory (release and debug) for
|
|
all of the required packages. This file will be included by the main
|
|
Makefile:
|
|
<repo_root>/compat/vcbuild/MSVC-DEFS-GEN
|
|
|
|
2. OPTIONALLY copy the third-party *.dll and *.pdb files into the repo
|
|
root to make it easier to run and debug git.exe without having to
|
|
manipulate your PATH. This is especially true for debug sessions in
|
|
Visual Studio.
|
|
|
|
Use ONE of the following forms which should match how you want to
|
|
compile git.exe.
|
|
|
|
$ ./compat/vcbuild/vcpkg_copy_packages.bat debug
|
|
$ ./compat/vcbuild/vcpkg_copy_packages.bat release
|
|
|
|
3. Build git using MSVC from an SDK bash window using one of the
|
|
following commands:
|
|
|
|
$ make MSVC=1
|
|
$ make MSVC=1 DEBUG=1
|
|
|
|
================================================================
|
|
|
|
Alternatively, run `make vcxproj` and then load the generated `git.sln` in
|
|
Visual Studio. The initial build will install the vcpkg system and build the
|
|
dependencies automatically. This will take a while.
|
|
|
|
Instead of generating the `git.sln` file yourself (which requires a full Git
|
|
for Windows SDK), you may want to consider fetching the `vs/master` branch of
|
|
https://github.com/git-for-windows/git instead (which is updated automatically
|
|
via CI running `make vcxproj`). The `vs/master` branch does not require a Git
|
|
for Windows to build, but you can run the test scripts in a regular Git Bash.
|
|
|
|
Note that `make vcxproj` will automatically add and commit the generated `.sln`
|
|
and `.vcxproj` files to the repo. This is necessary to allow building a
|
|
fully-testable Git in Visual Studio, where a regular Git Bash can be used to
|
|
run the test scripts (as opposed to a full Git for Windows SDK): a number of
|
|
build targets, such as Git commands implemented as Unix shell scripts (where
|
|
`@@SHELL_PATH@@` and other placeholders are interpolated) require a full-blown
|
|
Git for Windows SDK (which is about 10x the size of a regular Git for Windows
|
|
installation).
|
|
|
|
If your plan is to open a Pull Request with Git for Windows, it is a good idea
|
|
to drop this commit before submitting.

The Steps of Build Git with VS2008
|
|
|
|
1. You need the build environment, which contains the Git dependencies
|
|
to be able to compile, link and run Git with MSVC.
|
|
|
|
You can either use the binary repository:
|
|
|
|
WWW: http://repo.or.cz/w/msvcgit.git
|
|
Git: git clone git://repo.or.cz/msvcgit.git
|
|
Zip: http://repo.or.cz/w/msvcgit.git?a=snapshot;h=master;sf=zip
|
|
|
|
and call the setup_32bit_env.cmd batch script before compiling Git,
|
|
(see repo/package README for details), or the source repository:
|
|
|
|
WWW: http://repo.or.cz/w/gitbuild.git
|
|
Git: git clone git://repo.or.cz/gitbuild.git
|
|
Zip: (None, as it's a project with submodules)
|
|
|
|
and build the support libs as instructed in that repo/package.
|
|
|
|
2. Ensure you have the msysgit environment in your path, so you have
|
|
GNU Make, bash and perl available.
|
|
|
|
WWW: http://repo.or.cz/w/msysgit.git
|
|
Git: git clone git://repo.or.cz/msysgit.git
|
|
Zip: http://repo.or.cz/w/msysgit.git?a=snapshot;h=master;sf=zip
|
|
|
|
This environment is also needed when you use the resulting
|
|
executables, since Git might need to run scripts which are part of
|
|
the git operations.
|
|
|
|
3. Inside Git's directory run the command:
|
|
make command-list.h
|
|
to generate the command-list.h file needed to compile git.
|
|
|
|
4. Then either build Git with the GNU Make Makefile in the Git projects
|
|
root
|
|
make MSVC=1
|
|
or generate Visual Studio solution/projects (.sln/.vcproj) with the
|
|
command
|
|
perl contrib/buildsystems/generate -g Vcproj
|
|
and open and build the solution with the IDE
|
|
devenv git.sln /useenv
|
|
or build with the IDE build engine directly from the command line
|
|
devenv git.sln /useenv /build "Release|Win32"
|
|
The /useenv option is required, so Visual Studio picks up the
|
|
environment variables for the support libraries required to build
|
|
Git, which you set up in step 1.
|
|
|
|
Done!
