cmake --install failed on extras/ParseAndAddCatchTests.cmake, which the rename to Catch3 removed while CMakeLists.txt kept listing it. No job ran an install, so nothing showed it. The Linux job now installs the library and finds the installed package. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
C++17 is still the widest common target, and a library built on it stays usable from C++17 and every later standard, while C++20 would have left out many users. Concepts become enable_if on named traits in Detail/TypeTraits.hpp, which also replaces std::remove_cvref_t and std::identity. std::span becomes std::vector references, std::bit_cast becomes static_cast and memcpy, template lambdas become helper templates, and std::erase_if, contains, starts_with and ends_with have their C++17 forms. Random::Between no longer uses a lambda over a constexpr local, which MSVC rejects outside /permissive-, so the headers work under its default mode too. Tests give up designated initializers, which MSVC refuses in C++17. CI builds the matrix in C++17 and C++20, since the headers promise both.
macOS runners are the bottleneck of Progmasoft's CI: an organization runs at most five macOS jobs at a time, shared by every repository, and a pull request of Catch3 asked for about twenty of them. Every workflow also listened to both push and pull_request, so each pull request ran everything twice, once for its branch and once for the pull request. macOS now has one job, as in the Tala compiler: macOS 26 on Apple Silicon, Debug, C++17, with AddressSanitizer and UndefinedBehaviorSanitizer over the most-tests preset, examples and extra tests. The C++14 and C++17, Debug and Release matrix stays on Ubuntu and Fedora, where it already ran. ThreadSanitizer, which ran only on macOS, moves to a new Ubuntu job. The build systems that tested Windows and macOS (Bazel, Meson, Xmake, Premake) test Windows and Ubuntu instead, with Clang, so their Unix side is still covered and Linux is covered for the first time. The jobs that do not depend on the platform leave macOS: CodeQL (build mode none), the header and license checks, and native coverage, which now builds with the Clang and LLVM tools of Ubuntu instead of those of Xcode. Pushes build only devel; pull requests build their branches. The weekly CodeQL schedule stays. The required check "Bazel on macos-15" becomes "Bazel on ubuntu-26.04" in the branch protection and the ruleset when this is merged. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Catch2 compatibility means the API tests are written in: the macros, such as TEST_CASE and REQUIRE, and the Catch:: namespace. It does not mean Catch2's build names or header paths. find_package(Catch2) found Catch3, and a project using both frameworks met two packages, two sets of targets, two Catch.cmake modules and two catch2/ header trees with the same names. Build names: - CMake: project and package Catch3, targets Catch3::Catch3 and Catch3::Catch3WithMain, libraries Catch3 and Catch3Main, options CATCH3_*, lib/cmake/Catch3 with Catch3Config, and pkg-config catch3 and catch3-with-main. The version is Catch3's, 0.3.0, compatible within a minor version. - The CMake scripts are Catch3.cmake (catch3_discover_tests), Catch3AddTests.cmake and Catch3ShardTests.cmake (catch3_add_sharded_tests); the helpers they define at ctest time have a catch3_ prefix. ParseAndAddCatchTests.cmake, deprecated upstream, is gone. - Bazel //:catch3 and //:catch3_main, Meson catch3 and catch3-with-main (with override_dependency), Xmake catch3 and catch3_main, Premake Catch3 and Catch3WithMain. Visual Studio projects get GUIDs of their own. - The Progmasoft::Catch3 target and package are gone: property testing and snapshots are part of Catch3::Catch3. Their sources now build with the library's warning flags, so property failures are built field by field (no missing initializers) and the default property name is a thread-local pointer to the name its scope owns (no global destructor). Headers: the engine moved from src/catch2 to src/Progmasoft/Catch3 with Progmasoft names, so <catch2/catch_test_macros.hpp> is <Progmasoft/Catch3/TestMacros.hpp>, <catch2/matchers/catch_matchers_string.hpp> is <Progmasoft/Catch3/Matchers/String.hpp>, and interface headers are named after their interface, such as Interfaces/IConfig.hpp. Include guards became #pragma once. The installed headers go to include/Progmasoft. src/Progmasoft/Context.cpp is StrategyContext.cpp, so no two sources share a file name. tools/scripts/upstreamFiles.txt lists the files that come from Catch2. The license check expects BSL-1.0 on them and Progmasoft's header on the rest of src/Progmasoft; the convenience-header check, the amalgamation script and the surrogate tests take the engine's headers from it. The amalgamated files are regenerated. The header-guard workflow checks for #pragma once instead of checkguard. Documents, the README and the release notes describe the new names.
The compiler that uses this framework first is built and tested on Windows with the Visual Studio 2026 image, macOS 15 and 26, Ubuntu 26.04 and Fedora 43. This repository was tested on Windows Server 2022 and 2025, macOS 14, 15 and 15 on Intel, and on no Linux at all. The Windows builds move to the windows-2025-vs2026 image, in the basic builds and in the Xmake, Bazel and Meson builds. The macOS builds and the sanitizer builds run on macos-15 and macos-26. A new workflow builds and tests on Ubuntu 26.04 and, in a container, on Fedora 43, with Clang, as C++14 and C++17, Debug and Release. Two jobs stay on windows-2022: the Premake job generates Visual Studio 2022 projects, and the Conan job names the Visual Studio 17 generator and the v144 runtime. Moving them means moving those tools to Visual Studio 2026, which is a change of its own.
* Fixed problem with older compilers by explicitly installing the right compiler version. * Split apart simple builds that can be well described by a build matrix, and builds that need special CMake defines or similar special snowflake handling. * Ported some extras + examples builds from TravisCI to GitHub Actions.
