Bazel Support

Bazel Install

• Make sure that Bazel is installed on your system.

Ubuntu/Debian

Fedroa/Centos

Arch/Manjaro

sudo pacman -S bazel

Compile and build with bazel on flare

git clone https://github.com/Tencent/flare.git
cd flare

bazel build ...                      # compile all target
bazel test ...                       # compile and execute tests

• See this get more infomation
• ... Indicates recursively scan all targets, recognized as ../.. in oh-my-zsh, can be replaced by other shell or bash -c 'commond' to run, such as bash -c 'bazel build' ... or use bazel build ...:all

Using {flare} as a dependency

The following minimal example shows how to use {flare} as a dependency within a Bazel project.

The following file structure is assumed:

.
├── .bazelrc
├── BUILD.bazel
├── .gitignore
├── main.cc
├── REAMD.md
└── WORKSPACE.bazel

You can find these files in this directory.

main.cc

#include "flare/base/logging.h"

int main(int argc, char **argv) { FLARE_LOG_INFO("Hello flare!"); }

The expected output of this example is Hello flare!.

WORKSPACE.bazel
You can also use the http_archive method to download flare:

# Use http_archive
load("@bazel_tools//tools/build_defs/repo:http.bzl", "http_archive")
FLARE_VERSION = ""
FLARE_SHA256 = ""

http_archive(
    name = "com_github_tencent_flare",
    sha256 = FLARE_SHA256,
    urls = ["https://github.com/Tencent/flare/archive/refs/tags/{version}.zip".format(version = FLARE_VERSION)],
    strip_prefix = "flare-{version}".format(version = FLARE_VERSION),
)

load("@com_github_tencent_flare//bazel:deps.bzl", "flare_dependencies")

flare_dependencies()

load("@rules_foreign_cc//foreign_cc:repositories.bzl", "rules_foreign_cc_dependencies")

rules_foreign_cc_dependencies()

BUILD.bazel:

cc_binary(
    name = "main",
    srcs = ["main.cc"],
    deps = [
        "@com_github_tencent_flare//flare/base:logging",
    ],
)

The BUILD file defines a binary named main that has a dependency to {flare}.

To execute the binary, you can run bazel run //:main.
