Thanks, I tried it, actually adding --cxxopt='-std=c++11' to .bazelrc should work. – Rate

Answer 3

Besides setting it globally in .bazelrc or using BAZEL_CXXOPTS , you can also set them individually for each target in their cc_binary or cc_test rules:

cc_binary(
    name = "target1",
    srcs = ["target1.cc"],
    copts = ["--std=c++17"],
)

cc_binary(
    name = "target2",
    srcs = ["target2.cc"],
    copts = ["--std=c++14"],
)
