* PR #1498: Fix order of link options in pkg-config filesGravatar Stan Hu2023-07-31
| | | | | | | | | | | | | | | | | | | | | | | Imported from GitHub PR https://github.com/abseil/abseil-cpp/pull/1498 In Windows, a few libraries (`dbghelp`, `advapi32`, and `bcrypt`) are added via link options. However, the .pc files produced for pkg-config erroneously include them before the abseil libraries. This can cause undefined references when trying to build against abseil. This commit swaps the order and adds the custom link options after the abseil dependencies. The following is a list of `.pc` files affected by this and the additional link options used: * all: `-L${libdir}` * `absl_base.pc`: `-ladvapi32` * `absl_random_internal_seed_material.pc`: `-lbcrypt` * `absl_symbolize.pc`: `-ldbghelp` Closes https://github.com/abseil/abseil-cpp/issues/1497 Merge af61f6d5d5fa7b390fc2e009652cd6da68b0fd38 into c9c0fd5185067208e1cc4227d16122571762af39 Merging this change closes #1498 COPYBARA_INTEGRATE_REVIEW=https://github.com/abseil/abseil-cpp/pull/1498 from stanhu:sh-fix-pc-link-order af61f6d5d5fa7b390fc2e009652cd6da68b0fd38 PiperOrigin-RevId: 552564626 Change-Id: I9d2a6ab99993bb4315dc94eade2cd419f1109c13

* Fixed Windows DLL builds of test targetsGravatar Derek Mauro2023-05-12
| | | | | | | | | | | | | | | | | | | | | | | | | | This is a heavily modified version of https://github.com/abseil/abseil-cpp/pull/1445, which adds some missing test libraries to the test DLL. Unlike #1445, this change moves several global variables out of headers that did not need to be in headers. For instance, cord_btree_exhaustive_validation was a global defined/declared in cord_internal, but only used in cord_rep_btree and its test. cordz_handle defined a queue in its header even though it wasn't needed, which also led to ODR problems. The Spinlock used in CordzHandle is replaced with a Mutex. This was originally a Mutex, but Chromium asked us to change it to a Spinlock to avoid a static initializer. After this change, the static initializer is no longer an issue. #1407 PiperOrigin-RevId: 531516991 Change-Id: I0e431a193698b20ba03fac6e414c26f153f330a7

* Add an implementation of Waiter that uses std::mutex/std::condition_variableGravatar Derek Mauro2023-03-21
| | | | | | | | | | | | | | | This implementation may at some point become the default on some platforms. Currently not all platforms have widespread support for both real absolute timeouts or real relative timeouts (here "real" means without converting to the other timeout type which is the only one supported by the underlying APIs). In this case we can defer to their standard library to implement correct support. This is not currently the default on any platform Note: The size of WaiterState had to increase to fit the new implementation PiperOrigin-RevId: 518266646 Change-Id: I7f246646a960d6e1b155f9de0bf2f681c5d3d245
* Synchronization: Refactor Waiter to allow us to write testsGravatar Derek Mauro2023-03-20
| | | | | | | | | | | | | Instead of being only able to test the platform Waiter implementation, this allows us to be able to test all Waiter implementations that build on a specific platform. A unittest is added that tests all implementations that work for the platform, and allows us to check that the expected one is being used by printing the name of the selected implementation.

| | | | | | | The DLL export issue isn't a problem currently, since we don't explicitly export any symbols from the test dll. This will be an issue in the future though.

* CMake: Remove check_target calls which can be problematic in case of ↵Gravatar Abseil Team2022-10-10
| | | | | | | | | | | | | | | | | | | | | | | | | | dependency cycle Also renames `_target_compile_features_if_available` CMake function to `_absl_target_compile_features_if_available` since CMake's function namespace is global. The dependency cycle can occur if absl is configured with test helpers enabled, and googletest is configured to use absl. In the case that both projects are being built from source via FetchContent with OVERRIDE_FIND_PACKAGE, depending on the order in which the two projects are added to the build, the check_target calls may fail even though the build would have otherwise succeeded. The existing `check_target` calls seem to have been originally added to detect missing gtest targets when the `GTest::` prefix was not yet in use. For target names without "::", CMake does not warn if they are undefined, and just assumes they refer to system library names. However, CMake does fail during build generation if a target name with "::" is missing; thus the check_taget calls are redundant.

* CMake: install artifacts reflect the compiled ABIGravatar Abseil Team2022-09-06
| | | | | | | | | | | | | | | | | | Change `absl/base/options.h` at install time to reflect the ABI used to compile the libraries, i.e., if Abseil was compiled with C++ >= 17 then the `ABSL_OPTION_USE_STD_*` macros are set to `1`, because then the C++ 17 types are embedded in the ABI of the installed artifacts. Likewise, set the `target_compile_features()` of Abseil libraries to reflect the C++ version used to compile them. If they the Abseil libraries are compiled with C++ >= 17, then all downstream dependencies must also be compiled with C++ >= 17.

| | | | | When using Abseil as a dependency with CMake, files that include Abseil headers and have incompatible warning settings can emit compiler warnings. CMake allows you to mark include directories as `SYSTEM` includes, which causes compilers to ignore warnings from those headers. This adds the new option `ABSL_USE_SYSTEM_INCLUDES`, which makes Abseil's include directories be marked with `SYSTEM`.
