This showcases how to build a single file to create a runnable application.
This BUILD file shows that we want to build a C++ binary using the
cc_binary rule provided by Bazel.
cc_binary rule, name of the binary is specified in
name attribute (in this example, it's
hello-world), required source files to be built are provided in
cc_binary( name = "hello-world", srcs = ["hello-world.cc"], )
To build this example you use (notice that 3 slashes are required in windows)
bazel build //main:hello-world # In Windows, note the three slashes bazel build ///main:hello-world
If the build is successful, Bazel prints the following output:
____Loading complete. Analyzing... ____Found 1 target... ____Building... Target //main:hello-world up-to-date: C:/tools/msys64/tmp/_bazel_woden/vqeu6v3v/execroot/__main__/bazel-out/msvc_x64-fastbuild/bin/main/hello-world.exe ____Elapsed time: 0,400s, Critical Path: 0,01s
In the run log above you can see where the executable was built so you can locate it and use it.
