From dd2c5b58c4fe77d7ce35f3abb6e1bb399560a2db Mon Sep 17 00:00:00 2001 From: Egor Tensin Date: Sun, 17 Jan 2021 13:54:57 +0300 Subject: GIANT CLUSTERFUCK OF A COMMIT OK, this is epic. I was basically just trying to a) support Clang and b) add more test coverage. _THREE MONTHS_ and a few hundred CI runs later, this is what I came up with. I don't know how it ended up being what it is, but here we go. Some highlights of the changes: 1) CI builds has been moved to GitHub Actions, 2) the entire notion of a toolchain has been reworked; it now supports Clang on all platforms. * .github: this directory contains the GitHub Actions workflow scripts/actions. In the process, I created like 6 external GitHub actions, but it's still pretty massive. An upside is that it covers much more platform/toolchain combinations _and_ check a lot of the expected post-conditions. TODO: .ci/Makefile is obsolete now, as well as .travis.yml and .appveyor.yml. * common.cmake: added Clang support. In the process, a great deal has been learned about how CMake works; in particular, static runtime support has been reworked to be more robust. * project: the entire notion of a "toolchain" has been reworked. Instead of a measly --mingw parameter, there's now a separate --toolset parameter, which allows you to choose between GCC, Clang, MSVC, etc. Both Boost and CMake build scripts were enhanced greatly to support Clang and other toolchains in a more robust way. --- project/toolchain.py | 45 +++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 45 insertions(+) create mode 100644 project/toolchain.py (limited to 'project/toolchain.py') diff --git a/project/toolchain.py b/project/toolchain.py new file mode 100644 index 0000000..d931c6b --- /dev/null +++ b/project/toolchain.py @@ -0,0 +1,45 @@ +# Copyright (c) 2020 Egor Tensin +# This file is part of the "cmake-common" project. +# For details, see https://github.com/egor-tensin/cmake-common. +# Distributed under the MIT License. + +'''Supported platform/build system/compiler combinations include, but are not +limited to: + +* Linux / make / Clang, +* Linux / make / GCC, +* Linux / make / MinGW-w64, +* Windows / make / Clang (clang.exe & clang++.exe), +* Windows / make / Clang (clang-cl.exe, Boost 1.69.0 or higher only), +* Windows / make / MinGW-w64, +* Windows / msbuild / MSVC, +* Cygwin / make / Clang, +* Cygwin / make / GCC, +* Cygwin / make / MinGW-w64. +''' + +import argparse +from enum import Enum + + +class ToolchainType(Enum): + AUTO = 'auto' # This most commonly means GCC on Linux and MSVC on Windows. + MSVC = 'msvc' # Force MSVC. + GCC = 'gcc' # Force GCC. + MINGW = 'mingw' # As in MinGW-w64; GCC with the PLATFORM-w64-mingw32 prefix. + CLANG = 'clang' + CLANG_CL = 'clang-cl' + + def __str__(self): + return self.value + + @staticmethod + def all(): + return tuple(ToolchainType) + + @staticmethod + def parse(s): + try: + return ToolchainType(s) + except ValueError: + raise argparse.ArgumentTypeError(f'invalid toolset: {s}') -- cgit v1.2.3
