Building from Source¶

Bazel¶

To use glog within a project which uses the Bazel build tool, add the following lines to your WORKSPACE file:

WORKSPACE

load("@bazel_tools//tools/build_defs/repo:http.bzl", "http_archive")

http_archive(
    name = "com_github_gflags_gflags",
    sha256 = "34af2f15cf7367513b352bdcd2493ab14ce43692d2dcd9dfc499492966c64dcf",
    strip_prefix = "gflags-2.2.2",
    urls = ["https://github.com/gflags/gflags/archive/v2.2.2.tar.gz"],
)

http_archive(
    name = "com_github_google_glog",
    sha256 = "c17d85c03ad9630006ef32c7be7c65656aba2e7e2fbfc82226b7e680c771fc88",
    strip_prefix = "glog-0.7.1",
    urls = ["https://github.com/google/glog/archive/v0.7.1.zip"],
)

You can then add @com_github_google_glog//:glog to the deps section of a cc_binary or cc_library rule, and #include <glog/logging.h> to include it in your source code.

cc_binary(
    name = "main",
    srcs = ["main.cc"],
    deps = ["@com_github_google_glog//:glog"],
)

CMake¶

glog can be compiled using CMake on a wide range of platforms. The typical workflow for building glog on a Unix-like system with GNU Make as build tool is as follows:

Clone the repository and change into source directory.

git clone https://github.com/google/glog.git
cd glog

Run CMake to configure the build tree.
```
cmake -S . -B build -G "Unix Makefiles"
```
CMake provides different generators, and by default will pick the most relevant one to your environment. If you need a specific version of Visual Studio, use cmake . -G <generator-name>, and see cmake --help for the available generators. Also see -T <toolset-name>, which can be used to request the native x64 toolchain with -T host=x64.
Afterwards, generated files can be used to compile the project.
```
cmake --build build
```
Test the build software (optional).
```
cmake --build build --target test
```
Install the built files (optional).
```
cmake --build build --target install
```

Once successfully built, glog can be integrated into own projects.
