rusty_v8 | Rust bindings for the V8 JavaScript engine | Game Engine library

V8 is very large and takes a long time to compile. Many users will prefer to use a prebuilt version of V8. We publish static libs for every version of rusty v8 on Github. Binaries builds are turned on by default: cargo build will initiate a download from github to get the static lib. To disable this build using the V8_FROM_SOURCE environmental variable. When making changes to rusty_v8 itself, it should be tested by build from source. The CI always builds from source.
Use V8_FROM_SOURCE=1 cargo build -vv to build the crate completely from source. The build scripts on Python 2.7, not Python 3. Do not open issues with us regarding Python 3; it is a non-trivial problem that must be fixed in Chromium.. For linux builds: glib-2.0 development files need to be installed such that pkg-config can find them. On Ubuntu, run sudo apt install libglib2.0-dev to install them. For Windows builds: the 64-bit toolchain needs to be used. 32-bit targets are not supported. The build depends on several binary tools: gn, ninja and clang. The tools will automatically be downloaded, if they are not detected in the environment. Specifying the $GN and $NINJA environmental variables can be used to skip the download of gn and ninja. The clang download can be skipped by setting $CLANG_BASE_PATH to the directory containing a llvm/clang installation. V8 is known to rely on bleeding edge features, so LLVM v8.0+ or Apple clang 11.0+ is recommended. Arguments can be passed to gn by setting the $GN_ARGS environmental variable. Env vars used in when building from source: SCCACHE, CCACHE, GN, NINJA, CLANG_BASE_PATH, GN_ARGS.
