How to build cockroach DB with customized CFLAGS, CXXFLAGS and LDFLAGS?

Question

I would like to build cockroach DB with CFLAGS += -O, CXXFLAGS += -O and LDFLAGS ?= -static. How would I do that?

Answer 1

There are a couple of ways to do that.

(1) If you are building with make. You can simple open the make file and just find and override these flags.

(2) If you are building with bazel. You can set these flags with these bazel command options: --cxxopt=-O, --copt=-O, --linkopt=-static. For example: bazel build pkg/cmd/cockroach-oss --cxxopt=-O --copt=-O --linkopt=-static

(3) If you are building with crdb's dev tool (a wrapper of bazel). You can pass in the same options as (2) but following an extra --. For example, dev build oss -- --cxxopt=-O --copt=-O --linkopt=-static
