When True, CMake crosstool file will be generated from the toolchain values, provided cache-entries and env_vars (some values will still be passed as -Dkey=value and environment variables).
BAZEL VS CMAKE GENERATOR
Note that unless a generator ( -G) argument is provided, the default generators are Unix Makefiles for Linux and MacOS and Ninja for Windows. Arguments should be passed as key/value pairs. For example, additional CXXFLAGS.Īrguments for CMake's generate command. No other macros are supported.ĬMake environment variable values to join with toolchain-defined. $(execpath) macros may be used to point at files which are listed as data deps, tools_deps, or additional_tools, but unlike with other rules, these will be replaced with absolute paths to those files, because the build does not run in the exec root. those that the external buidl system will be looking for and paths to which are provided by the calling rule)Įnvironment variables to set during the build. Typically those directly required for the external building of the library/binaries. Optional dependencies to be copied into the directory structure.
They are NOT passed to the compiler, you should duplicate them in the configuration options. Optional compilation definitions to be passed to the dependencies of this library. (Toolchain values come first)įiles needed by this rule at runtime. if true, link all the object files from the static library, even if they are not used.ĬMake cache entries to initialize (they will be passed with -Dkey=value) Values, defined by the toolchain, will be joined with the values, passed here. Not used by the shell script part in cc_external_rule_impl. Optional additional tools needed for the building. Optional additional inputs to be declared as needed for the shell script action.Not used by the shell script part in cc_external_rule_impl.
Rule for building external library with CMake. lib/hello.lib as the result of the build examples/cmake_hello_world_lib):Įxample assumes that MS Visual Studio and Ninja are installed on the host machine, and Ninja bin directory is added to PATH.
BAZEL VS CMAKE FULL
lib is assumed for the static libraries by default.Įxample usage (see full example in. The tested generators: Visual Studio 15, Ninja and NMake. The default generator for CMake will be detected automatically, or you can specify it explicitly. When using on Windows, you should start Bazel in MSYS2 shell, as the shell script inside cmake assumes this.Īlso, you should explicitly specify make commands and option to generate CMake crosstool file. # This sets up some common toolchains for building targets. # Rule repository, note that it's recommended to use a pinned commit to a released version of the rules
In WORKSPACE.bazel, put workspace(name = "rules_foreign_cc_usage_example")
