"""Config settings for compilers identified by Bazel.
|
|
|
|
Targets that require compiler-specific flags can use the config_settings defined
|
|
in this package in their select() statements.
|
|
|
|
*Note*: Before Bazel 6, gcc on Linux and clang on macOS would not match their
|
|
specific config_setting, but only the fallback case of a select expression.
|
|
|
|
Toolchains not shipped with Bazel are encouraged to use the same names to
|
|
identify compilers as used below, but this is not enforced.
|
|
|
|
Example:
|
|
|
|
cc_binary(
|
|
name = "foo",
|
|
srcs = ["foo.cc"],
|
|
copts = select({
|
|
"//cc/compiler:gcc": [...],
|
|
"//cc/compiler:clang": [...],
|
|
"//cc/compiler:msvc-cl": [...],
|
|
# Fallback case for an undetected compiler.
|
|
"//conditions:default": [...],
|
|
}),
|
|
)
|
|
|
|
If multiple targets use the same set of conditionally enabled flags, this can be
|
|
simplified by extracting the select expression into a Starlark constant.
