Learn to use Bazel

My goal here is to learn to use Bazel as a C++ build tool for Linux

It is meant as the basis for a tutorial and a comparison with other tools

1. install Bazel
2. clone this repo

git clone http://github.com/alichnewsky/learn-bazel.git
cd learn-bazel
git submodule update --init

1. build

bazel build -c opt --verbose_failures //mylib:all
bazel build -c opt //examples/tbb:all

1. test

bazel test -c opt //mylib:all
bazel test -c opt //examples/tbb:all

I have not yet figured out:

• how I packaged software built with Bazel
• how I make sure I distribute and link with the right libraries: libmylib.so not libmylib_Slibmylib.so
• Can I strip the symbols from objects not part of a library's API (declare what symbols I want to export or strip)
• how to use third_party and //external correctly
  • I have examples in another repo, but not this one
• how to use other bazel repos as third party and let their own?
• how to use gtest as part of cc_test targets (I think it's trivial)
• how do I use both gcc and clang to build
• how do I add additional rules for language meant to link with C/C++
  • fortran
  • ispc
