22 * Pass `--cxxopt=-std=c++17` on the command line (for example, `bazel build
23 --cxxopt=-std=c++17 ...`)
25 `BAZEL_CXXOPTS=-std=c++17`)
26 * Add `build --cxxopt=-std=c++17` to your [`.bazelrc`
27 file](https://docs.bazel.build/versions/master/guide.html#bazelrc)
29 If you are using CMake as the build system, you'll need to add a line like
30 `set(CMAKE_CXX_STANDARD 17)` to your top level `CMakeLists.txt` file. See the

40 ## What is ABI and why don't you recommend using a pre-compiled version of Abseil?
52 [Bazel](https://bazel.build/) `BUILD` file:
59 copts = ["-std=c++17"], # May create a mixed-mode compile!
64 Applying `-std=c++17` to an individual target in your `BUILD` file is going to
65 compile that specific target in C++17 mode, but it isn't going to ensure the
66 Abseil library is built in C++17 mode, since the Abseil library itself is a
67 different build target. If your code includes an Abseil header, then your
70 the ABI of a program need to be applied to the entire build on a global basis.
79 If you build the Abseil library and your code using different compile options

83 code generation flags (e.g. `-fexceptions`), and preprocessor defines
84 (e.g. `-DNDEBUG`).
86 If you use a pre-compiled version of Abseil, (for example, from your Linux
