build2 | Installation
The universal way to install or upgrade build2 is using the
automated install scripts. Download a version for your platform (see below),
verify its checksum, run, and follow the onscreen instructions. The script
will prompt for your confirmation before building or installing anything.
See the Installation FAQ for common
installation questions and Other Installation Methods
for alternatives (binary packages, etc).
To build and install build2 all you will need is a
reasonably recent C++ compiler. See Which compilers are supported? for
details.
You will normally want to keep the build directory around for upgrades or to cleanly uninstall the toolchain. An automated upgrade can be performed from any previous patch release and from the most recent previous minor version.

1 UNIX (Linux, Mac OS, FreeBSD)
The build2 binary packages are available in Fedora, Homebrew, FreeBSD,
and several other Linux distributions.
Create the build2 build directory, for example
~/build2-build in your home directory, then run:
$ cd ~/build2-build $ curl -sSfO https://download.build2.org/0.17.0/build2-install-0.17.0.sh $ shasum -a 256 -b build2-install-0.17.0.sh b84e4114c61aa94c3f6278f010a0dc0536dda65ac39d3863152ec9b64510b86e $ sh build2-install-0.17.0.sh
Or, to upgrade from 0.16.0:
$ sh build2-install-0.17.0.sh --upgrade
To uninstall:
$ sh build2-install-0.17.0.sh --uninstall
See the Installation FAQ for common platform-specific issues and solutions.
2 Windows with MSVC
Create the build2 build directory, for example,
C:\build2-build, download build2-install-msvc-0.17.0.bat
into it, start the Visual Studio x64 Command Prompt,
then run:
> cd C:\build2-build > certutil -hashfile build2-install-msvc-0.17.0.bat SHA256 9af34586cbe32360fa783883446cd90033152a1225c73acd92b45a95beafa695 > build2-install-msvc-0.17.0.bat
If your organization's network security breaks the installation process
(often the case on Windows when trying to use curl), then
consider installing offline.
Or, to upgrade from 0.16.0:
> build2-install-msvc-0.17.0.bat --upgrade
Note that currently the automated upgrade process does not upgrade the baseutils
package. Use the from-scratch installation if you would like to upgrade
this package.
To uninstall:
$ build2-install-msvc-0.17.0.bat --uninstall
See the Installation FAQ for common Windows-specific issues and solutions.
3 Windows with Clang
There are two common ways to obtain Clang targeting the MSVC runtime: bundled with the MSVC installation (by selecting the Clang tools component in the Visual Studio installer) or as a separate installation (by getting the installer from the LLVM Download page).
If you are using a separate installation, then the Clang compiler is most
likely already in your PATH environment variable and you don't
have to use the Visual Studio command prompt below.
Create the build2 build directory, for example,
C:\build2-build, download build2-install-clang-0.17.0.bat
into it, start the Visual Studio x64 Command Prompt,
then run:
> cd C:\build2-build > certutil -hashfile build2-install-clang-0.17.0.bat SHA256 a612a7761774c4602a7633eb9b1acc791f8c51771fdb59c7b43a878ffec5d7fc > build2-install-clang-0.17.0.bat
If your organization's network security breaks the installation process
(often the case on Windows when trying to use curl), then
consider installing offline.
Or, to upgrade from 0.16.0:
> build2-install-clang-0.17.0.bat --upgrade
Note that currently the automated upgrade process does not upgrade the baseutils
package. Use the from-scratch installation if you would like to upgrade
this package.
To uninstall:
$ build2-install-clang-0.17.0.bat --uninstall
See the Installation FAQ for common Windows-specific issues and solutions.
4 Windows with MinGW
Create the build2 build directory, for example,
C:\build2-build, download build2-install-mingw-0.17.0.bat
into it, start the Command Prompt, then run:
> cd C:\build2-build > certutil -hashfile build2-install-mingw-0.17.0.bat SHA256 ddd3cbfbc5927cc1736cadf3bdb6395c8261a3bebfedb2bb83e72f3964ad1bb8 > build2-install-mingw-0.17.0.bat
If your organization's network security breaks the installation process
(often the case on Windows when trying to use curl), then
consider installing offline.
The build2-install-mingw script downloads and installs (into
the same directory as build2) a minimal MinGW GCC distribution
that is then used to compile build2. If you would prefer to use
your own MinGW GCC, see the alternative installation methods below.
Or, to upgrade from 0.16.0:
> build2-install-mingw-0.17.0.bat --upgrade
Note that currently the automated upgrade process does not upgrade the baseutils
and mingw packages. Use the from-scratch installation if
you would like to upgrade these packages.
To uninstall:
$ build2-install-mingw-0.17.0.bat --uninstall
See the Installation FAQ for common Windows-specific issues and solutions.
5 Other Installation Methods
The steps described above are the preferred way to install
build2 for most developers. For alternative from-source
installation methods that offer more control see the Installation and
Upgrade manual. To manually obtain various components of the
build2 toolchain refer to the Download page.
The build2 binary packages are also available in several
distribution package repositories, see: Fedora, Homebrew, FreeBSD,
Gentoo,
and Arch Linux.
There is also the setup-build2
GitHub Action.
