I believe I saw in the CI run that `storage_client` was missing or something, as the google-cloud-cpp package has [started namespacing its exports](https://github.com/googleapis/google-cloud-cpp/blob/5bf147226e9333c5106d5fc8b8bba62657eeab97/google/cloud/storage/legacy.cmake.in#L28) (finally!). Given the hard link against abseil libraries (as gRPC does too), to reduce packaging size, I decided that the version was safer pinned. The abseil libraries actually loaded probably depends on the matrix of abseil versions and users of it (gRPC, and the proposed google-cloud-cpp inclusion). Personally, I extract it by a bazel query (provided in comments) and a Python script to lookup the symbols in the ar files. I believe the gRPC builds do something similar, or just pull them out from the compiler invocations (does @pitrou or @kou know how they were determined in commits like [these](https://github.com/apache/arrow/commit/4ecac056dfa88a0032fed7f36a20d2886c39ef90)?). Ideally the compiler would do it, but I didn't dig into why the build system wouldn't allow so (I'm guessing the libs have to bundled in and linked separately somehow?). I'm hoping to upgrade the dependency when there is code using it (which would be the GCS implementation of the Arrow file interfaces). ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
