Extract compiler and linker flags from Bazel

Question

I need to extract the compiler flags and linker flags for a certain application that is built by Bazel.

Is there a specific command to do so?

Answer 1

bazel clean # force bazel to rebuild everything  
bazel build -s //...

There are more advanced approaches, e.g.:

• kythe
• Hedron's Compile Commands Extractor for Bazel
• https://github.com/vincent-picaud/Bazel_and_CompileCommands

You can also use system tools such as strace to figure how what tools are called by Bazel and which command line parameters are involved.
