Fuchsia OS build command: fx set --with, produces: Include not allowed

Question

fuchsia/examples/intl/tz_version_parrot/main.cc uses fxl::CommandLineFromArgcArgv():

#include \"src/lib/fxl/command_line.h\"
...
int main(int argc,          


        

Answer 1

In ./examples/hello_world/cpp/BUILD.gn, extend the hello_world_cpp module declaration with the fxl dependency:

executable("bin") {
  output_name = "hello_world_cpp"

  sources = [ "hello_world.cc" ]

  deps = [ "//src/lib/fxl" ] # Add this line
}

cd fuchsia
fx set bringup.x64 --with //examples/hello_world
fx build; fx qemu
...
hello_world_cpp
hello has_argv0():1

Reference: The same is done in other Fuchsia components that use fxl (link).
