The following instructions are for bootstrapping \c{build2} with either MSVC
or MinGW using the Windows command prompt. If you are using any kind of UNIX
emulation layer (for example, MSYS or Cygwin) and already have a UNIX shell
with standard utilities, then you most likely should follow \l{#BOOTSTRAP-UNIX
Bootstrapping on UNIX} instead.
The \c{build2} toolchain on Windows requires a set of extra utilities
(\c{install}, \c{diff}, \c{wget}, \c{tar}, etc). These are provided by the
\c{build2-baseutils} package (see the \c{README} file inside for details).
Normally, the \c{build2} toolchain itself is installed into the same directory
as the utilities in order to produce the combined installation.
To build on Windows you will need either MSVC 14 Update 2 or later or MinGW
GCC 4.8 or later. Note also that MinGW GCC must be configured with the
\c{posix} threading model (this is currently the only configuration that
implements C++11 threads; run \c{g++ --version} to verify).
If you don't already have a suitable C++ compiler, then you can use the
\c{build2-mingw} package which provides a minimal MinGW-W64 GCC distribution
(see the \c{README} file inside for details). If used, then it should be
unpacked into the same directory as \c{build2-baseutils}.
To bootstrap on Windows with either MSVC or MinGW start with the following
common steps:
\dl|
\li|1. Open Command Prompt\n
Start the standard Windows Command Prompt. If you plan to build with MSVC,
then you may go ahead and start the Visual Studio Command Prompt (or wait
until MSVC-specific instructions).
|
\li|\n2. Create Build Directory\n
Note that you will want to keep this directory around in order to upgrade
to new toolchain versions in the future. In this guide we will use
\c{C:\\build2-build\\} as the build directory and \c{C:\\build2\\} as the
installation directory but you can use other paths.
\
> C:
> cd \
> mkdir build2-build
> cd build2-build
\
|
\li|\n3. Download Archives\n
Download the following files as well as their \c{.sha256} checksums from
\l{https://download.build2.org}, replacing \i{<arch>} with \c{x86_64} for
64-bin Windows and with \c{i686} for 32-bit.
\
build2-baseutils-X.Y.Z-<arch>.zip
build2-mingw-X.Y.Z-<arch>.tar.xz (if required)
build2-toolchain-X.Y.Z.tar.xz
\
Place everything into \c{C:\\build2-build\\} (build directory).|
\li|\n4. Verify Archive Checksums\n
Verify archive checksums match (compare visually):
\
> type *.sha256
> for %f in (*.zip *.xz) do certutil -hashfile %f SHA256
\
|
\li|\n5. Unpack \c{build2-baseutils}\n
Unpack the \c{build2-baseutils-X.Y.Z-<arch>.zip} archive into \c{C:\\} using
Windows Explorer (for example, copy the archive directory and then paste it).
Rename it to \c{C:\\build2\\}. This will be the toolchain installation
directory.
|
\li|\n6. Set \c{PATH}\n
Set the \c{PATH} environment variable and verify the utilities are found and
work:
\
> set PATH=C:\build2\bin;%PATH%
> where tar
> tar --version
\
|
\li|\n7. Unpack \c{build2-mingw}\n
If required, unpack the \c{build2-mingw-X.Y.Z-<arch>.tar.xz} archive into
\c{C:\\build2\\}:
\
> tar xf build2-mingw-X.Y.Z-<arch>-windows.tar.xz ^
--one-top-level=C:\build2 --strip-components=1
\
Verify the MinGW GCC is found and works:
\
> where g++
> g++ --version
\
|
\li|\n8. Unpack \c{build2-toolchain}\n
Unpack the \c{build2-toolchain-X.Y.Z.tar.xz} archive and change to its
directory:
\
> tar xf build2-toolchain-X.Y.Z.tar.xz
> cd build2-toolchain-X.Y.Z
\
||
If building with MSVC, continue with \l{#BOOTSTRAP-MSVC Bootstrapping with
MSVC}.
If building with MinGW, continue with \l{#BOOTSTRAP-MINGW Bootstrapping with
MINGW}.
