Building Git

We build Git for Windows using an MSYS2 based Git for Windows SDK. This SDK can be installed via the SDK installer

Installing a build environment

1. Just run the SDK installer.

Build Git

1. An initial git clone and make should have already occurred when running the SDK installer.

2. Open the Git for Windows SDK MinGW shell by double clicking either the Shortcut on the desktop Git SDK 32-bit.lnk or by double clicking mingw32_shell.bat in the install folder. That is Git SDK 64-bit.lnk and mingw64_shell.bat for the 64bit SDK installer.

3. Change directory to the initial clone: cd /usr/src/git.

4. (Optional) build Git: make install

5. Run the test suite: make test. If you are a fan of statistics, you can use the following prove invocation to run the testsuite. But first we have to change to the test directory with the command cd t. After that you can issue /usr/bin/time prove -j 15 --state=failed,save ./t[0-9]*.sh. If 15 threads are too many for your system, you can provide the number of threads via the -j <num> (j for jobs) parameter.

Updating to the newest Git for Windows version

cd /usr/src/git
git pull
make -j15 install install-html

Testing the new Git version

As before:

cd /usr/src/git/t
/usr/bin/time prove -j 5 --state=failed,save ./t[0-9]*.sh

See also Regression Testing

Single tests, block of tests, or the whole test suite can be run, as detailed in Running Git's regression-tests
