The problem is that cmake TARGET names are not scoped thus the name clash, on my way to provide a patch in google/or-tools then a PR here...
would go for
# change logical target name
add_library(status_py_extension_stub SHARED status_py_extension_stub.cc)
# but keep the previous base name, "status" for the output file...
set_target_properties(status_py_extension_stub PROPERTIES LIBRARY_OUTPUT_NAME "status")
# we can keep the ALIAS unchanged to pybind11_abseil::status
add_library(pybind11_abseil::status ALIAS status_py_extension_stub)Deprecated Abseil types ie.(`Breakdown`) in use
It appears that pybind11_abseil uses deprecated types. ie. Breakdown, From_Datetime. Will/when will this be updated?
These issues seem to appear even when using the 20230802.0 tag of abseil-cpp as specified in the WORKSPACE file.
For a more complete example of the deprecated features see a failed build:

Nanobind port
Nanobind looks fairly stable at this point. I recently got nanobind to work with my various Bazel projects and considering doing a port.
Are there any plans to release a nanobind_abseil? If not, I'm happy to take a stab at it in my spare time.
Python bindings for absl::Status cause ODR violation
The issue can manifest itself in multiple ways. One of the most straightforward examples is that returning an absl::Status with a payload from C++ to Python can cause the process to crash (approximately 1 in 50k times; code that reproduces the issue: https://github.com/apronchenkov/pybind11_absl_cord_odr_issue).
It appears that the root cause of the issue seems is that pybind11_abseil includes statically linked components of Abseil, which may conflict with Abseil usages within the Python extensions.
Error when converting absl::Span<const bool>
When trying to specify a py::arg with C++ type absl::Span (or more specifically in my case absl::optional<absl::Span>), I get an compile error:
./third_party/pybind11_abseil/absl_casters.h:378:12: error: no matching function for call to 'MakeSpan'
return absl::MakeSpan(static_cast<std::vector<value_type>&>(caster));
...
I guess this might be related to std::vector being potentially specialized as a bitset instead of an array of byte sized bools (abseil/abseil-cpp#644). It would be nice to be able to define an py::arg as absl::Span though if it's possible to side-step this issue.
How to use this library in cmake build-system
as the header
Support for absl::InlinedVector<T, N>?
I have a function that returns absl::InlinedVector<float, 4>, as well as a struct that contains one as a member.
I'm happy to implement this but would like to entertain suggestions for API design, especially for generic types T.
ReadMe outdated and broken links
PYBIND11_ABSEIL_STATUS_MODULE_PATH Does not seem to exist in status_casters.h
This seems to make https://github.com/pybind/pybind11_abseil#use-outside-of-google3 irrelevant?
Additionally the "it's documentation" link in https://github.com/pybind/pybind11_abseil#importing-the-status-module is broken.
CMake linking and install improvements
Hi,
I am a packager for openSUSE and am trying to build RPM packages for pybind11_abseil. We found that we need a few changes to the cmake scripts to improve the package finding logic, linking to the right version of Python, and installation of headers. I list the patches we use one by one in this description, so that you may have a look and see if they are right for your project. If you agree, I can submit PRs for the changes.
Pass FIND_PACKAGE_ARGS to FetchContent_Declare
This enables the detection of system absl and pybind11 and goes on to download them if they are not. Important for packaging on openSUSE because RPMs are built inside a no-network access VM.
Note: This will bump the CMake minimum version to 3.24.

This is needed in any case for our packages to avoid undefined reference to Py* errors when linking, but additionally it helps to build against the correct version of Python and Pybind11 if there are multiple ones installed in the system. On openSUSE, it is natural to have simultaneously python3.10, python3.11, and python3.12 and the corresponding pybind11, numpy, python-absl installed in the system. This helps pick the right pybind11 to go with the choice of python executable.

Apparently the current CMake scripts do not install the headers to the system, only the libraries. Headers are nonetheless needed for devs using C++ interface of pybind11_abseil. This patch adds the necessary include dirs to the install destination.

Provide a fine grained mechanism for specifying `PYBIND11_ABSEIL_STATUS_MODULE_PATH`
I am using pybind11_abseil with pybind11_bazel.
I recently updated pybind11_abseil to HEAD and was surprised when my tests failed trying to import pybind11_absil.status. It took some time to track down the offending line to pybind11::google::ImportStatusModule(); on the C++ side and then to track down how the path is discovered.
With Bazel and assuming the default external repository name of pybind11_abseil, the corresponding Python import is from pybind11_abseil.pybind11_abseil import status. It took a while to find the relevant #define in README.md.
As the README accurately states, one must pass -D PYBIND11_ABSEIL_STATUS_MODULE_PATH=<path> directly on the command line (via bazel build --cxxopt="-D ...").
I was hoping for a more fine grained customization point via a macro that wraps @pybind11_abseil//pybind11_abseil:status_casters. At the moment, it is a pure pybind_library with no way to pass a defines or local_defines without setting --cxxopt globally.
ImportError: generic_type: cannot initialize type "StatusCode": an object with that name is already defined
Hi,
I am trying to figure out some issues with using the pybind11_abseil.status usage. TensorFlow as well as some other Google projects are using the pybind11_abseil modules. I found that as of TensorFlow 2.14.0 (2.13.1 is fine), it looks like that using TensorFlow in conjunction with packages that use pybind11_abseil will fail with the error
ImportError: generic_type: cannot initialize type "StatusCode": an object with that name is already defined
This happens for example in google-deepmind/launchpad#44 and tensorflow/tflite-support#954. The error happens when a pybind11 extension that uses
py::google::ImportStatusModule() is called.
For example
import tensorflow
import launchpad # Fails when importing an extension that uses ImportStatusModule.Reversing the order we will see the same issues this time coming from TensorFlow trying to import a module that uses
ImportStatusModule.
I noticed that there are some changes to the pybind11_abseil version used in TensorFlow 2.14.0, which incoporates some changes around the import_status_module, but I don't have a really good clue about what that change entails, it would be quite useful if you can provide some help.
Thanks!
Test `AbslTimeTest.test_pass_datetime_pre_unix_epoch` fails on 32-bit i586 architecture
Using pybind11_abseil 202402.0, python 3.10, on 32-bit architecture, we see the following error when running ctest after building the library. I understand if 32 bit archs are not supported, but I just wanted to report here before disabling these builds.
Thanks in advance.

`status.so` does not build on MacOS with proper cc toolchain registration
Modern apple_support sets up a proper Apple CC toolchain.
One consequence of this is that the linker flag -undefined dynamic_lookup is no longer on by default (this was a bug. ld's default is -undefined error).
When switching to the modern toolchain, it causes status.so to fail because it does not depend on @pybind11//:pybind11. For these .sos, we should pass linkopts = ["-undefined", "dynamic_lookup"], as pybind_extension does here.
I'm happy to author a PR.
