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, WSL, 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.
\N|Note that if you continue with these instructions but you already have your
own installation of MSYS and/or MinGW, then make sure that their paths are not
in your \c{PATH} environment variable when building and using \c{build2} since
they may provide conflicting DLLs.|
The \c{build2} toolchain on Windows requires a set of extra utilities
(\c{install}, \c{diff}, \c{curl}, \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 3 or later or MinGW
GCC 4.9 or later. 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}.
\N|If using your own MinGW GCC installation, make sure it is configured with
the \c{posix} threading model (this is currently the only configuration that
implements C++11 threads; run \c{g++ -v} to verify).|
\N|Only 64-bit variants of the \c{baseutils} and \c{mingw} packages are
provided and they \b{must} match the width of the \c{build2} toolchain. Note
also that the 64-bit \c{build2} toolchain can be used to build 32-bit
applications without any restrictions.|
To bootstrap on Windows with either MSVC or MinGW start with the following
common steps:
\dl|
\li|\b{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 \"x64 Native Tools Command
Prompt\" (or wait for MSVC-specific instructions).|
\li|\n\b{2. Create Build Directory}\n
You will want to keep this directory around in order to upgrade to new
toolchain versions in the future. In this guide we use \c{C:\\build2-build\\}
as the build directory and \c{C:\\build2\\} as the installation directory but
you can use other paths.
\
> cd /D C:\
> mkdir build2-build
> cd build2-build
\
|
\li|\n\b{3. Download Archives}\n
Download the following files as well as their \c{.sha256} checksums from the
\l{https://build2.org/download.xhtml Download} page:
\
build2-baseutils-X.Y.Z-x86_64-windows.zip
build2-mingw-X.Y.Z-x86_64-windows.tar.xz (if required)
build2-toolchain-X.Y.Z.tar.xz
\
Place everything into \c{C:\\build2-build\\} (build directory).|
\li|\n\b{4. Verify Archive Checksums}\n
Verify archive checksums match (compare visually):
\
> type *.sha256
> for %f in (*.zip *.xz) do certutil -hashfile %f SHA256
\
|
\li|\n\b{5. Unpack \c{build2-baseutils}}\n
Unpack the \c{build2-baseutils-X.Y.Z-x86_64-windows.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|\n\b{6. Set \c{PATH}}\n
Set the \c{PATH} environment variable and verify that the utilities are found
and work:
\
> set PATH=C:\build2\bin;%PATH%
> where tar
> tar --version
\
|
\li|\n\b{7. Unpack \c{build2-mingw} (optional)}\n
If required, unpack the \c{build2-mingw-X.Y.Z-x86_64-windows.tar.xz} archive
into \c{C:\\build2\\}:
\
> xz -d build2-mingw-X.Y.Z-x86_64-windows.tar.xz
> tar -xf build2-mingw-X.Y.Z-x86_64-windows.tar ^
--one-top-level=C:\build2 --strip-components=1
\
Verify that the MinGW GCC is found and works:
\
> where g++
> g++ --version
\
|
\li|\n\b{8. Unpack \c{build2-toolchain}}\n
Unpack the \c{build2-toolchain-X.Y.Z.tar.xz} archive and change to its
directory:
\
> xz -d build2-toolchain-X.Y.Z.tar.xz
> tar -xf build2-toolchain-X.Y.Z.tar
> cd build2-toolchain-X.Y.Z
\
||
If building with MSVC, continue with \l{#bootstrap-windows-msvc Bootstrapping
on Windows with MSVC}.
If building with MinGW, continue with \l{#bootstrap-windows-mingw
Bootstrapping on Windows with MinGW}.
