Rust build system module for build2.
For build instructions see libbuild2-hello/README.
You can pass "compiler mode" options, such as +nightly, as part of
config.rust, for example, in your project:
$ b configure config.rust="rustc +nightly"
Or when initializing libbuild2-rust-tests:
bdep init @target -d libbuild2-rust-tests/ config.rust="rustc +nightly"
It's possible to cross-compile for the Windows target with lld. First
install lld, for example, using your system's package manager. You will also
need to copy Windows Platform SDK and Visual Studio libraries. Here we assume
the setup suggested in msvc-linux
which also allows us to run tests under Wine emulation. Alternatively, just
copy over the directories listed below.
Once this is done, use the command line along these lines adjusting the Platform SDK and Visual Studio versions to match your setup:
$ b config.rust="rustc \
--target=x86_64-pc-windows-msvc \
-C linker=lld-link \
-C link-arg='/LIBPATH:$HOME/.wine/drive_c/Program Files (x86)/Microsoft Visual Studio/2019/Community/VC/Tools/MSVC/14.20.27508/lib/x64' \
-C link-arg='/LIBPATH:$HOME/.wine/drive_c/Program Files (x86)/Windows Kits/10/Lib/10.0.14393/um/x64' \
-C link-arg='/LIBPATH:$HOME/.wine/drive_c/Program Files (x86)/Windows Kits/10/Lib/10.0.14393/ucrt/x64'"
