bazel aquery 'mnemonic("Cpp.*", deps( //main:hello-world))' --platforms=//platform:linux_x64 --output=jsonproto >> 3.txt
In this stage we step it up and showcase how to integrate multiple cc_library targets from different packages.
Below, we see a similar configuration from Stage 2, except that this BUILD file is in a subdirectory called lib. In Bazel, subdirectories containing BUILD files are known as packages. The new property visibility will tell Bazel which package(s) can reference this target, in this case the //main package can use hello-time library.
cc_library(
name = "hello-time",
srcs = ["hello-time.cc"],
hdrs = ["hello-time.h"],
visibility = ["//main:__pkg__"],
)
To use our hello-time library, an extra dependency is added in the form of //path/to/package:target_name, in this case, it's //lib:hello-time
cc_binary(
name = "hello-world",
srcs = ["hello-world.cc"],
deps = [
":hello-greet",
"//lib:hello-time",
],
)
To build this example, use
bazel build //main:hello-world
