C++ toolchain: modify deafult ar params

[Manish Singh]

Hi,
after running bazel aquery coommand ,
I see following params for cpparchive

  "/usr/bin/ar",
         "rcsD",
         "bazel-out/k8-fastbuild/bin/lib/libhello-time.a",
         "bazel-out/k8-fastbuild/bin/lib/_objs/hello-time/hello-time.pic.o",
         "@bazel-out/k8-fastbuild/bin/lib/libhello-time.a-2.params"
         
Here I see some default ar parameters like 'rcsD'

I am looking a way to customize the default paramters passed to ar.

Appreciate help.

This seems to be controlled by a C++ toolchain feature named `archiver_flags`.

I don't know of an easy way to change the values, without redefining your own C++ toolchain definition (which in itself is a major undertaking), maybe someone on the list has an idea though?

Thank you, I have already implemented toolchain.
