Abseil C++#
The $dir_pw_third_party/abseil-cpp/
module provides build files to allow
optionally including upstream Abseil C++.
Using upstream Abseil C++#
If you want to use Abseil C++, you must do the following:
Submodule#
Add Abseil C++ to your workspace with the following command.
git submodule add https://github.com/abseil/abseil-cpp.git \
third_party/abseil-cpp/src
GN#
Set the GN var
dir_pw_third_party_abseil-cpp
to the location of the Abseil C++ source.If you used the command above, this will be
//third_party/abseil-cpp/src
This can be set in your args.gn or .gn file like:
dir_pw_third_party_abseil_cpp = "//third_party/abseil-cpp/src"
Updating#
The GN build files are generated from the third-party Bazel build files using $dir_pw_build/py/pw_build/generate_3p_gn.py.
The script uses data taken from $dir_pw_third_party/abseil-cpp/repo.json
.
The script should be re-run whenever the submodule is updated or the JSON file
is modified. Specify the location of the Bazel repository can be specified using
the -w
option, e.g.
python pw_build/py/pw_build/generate_3p_gn.py \
-w third_party/abseil-cpp/src
Version#
The update script was last run for revision 67f9650.
