2022-04-15Get rid of target::dynamic_type() virtual functionBoris Kolpackov2-53/+131
Instead of overriding this function, derived targets must now set the dynamic_type variable to their static_type in their constructor body.

2022-04-06Add support for rule hintsBoris Kolpackov6-38/+39
A rule hint is a target attribute, for example: [rule_hint=cxx] exe{hello}: c{hello} Rule hints can be used to resolve ambiguity when multiple rules match the same target as well as to override an unambiguous match.

2021-06-30Move symbol exporting .def file rule to bin.def module, add support for MinGWBoris Kolpackov3-153/+284
The bin.def module is automatically loaded by the c and cxx modules for the *-win32-msvc target architecture. This allows automatically exporting all symbols for all Windows targets using the following setup (showing for cxx in this example): lib{foo}: libul{foo}: {hxx cxx}{**} ... lib{foo}: def{foo}: include = ($cxx.target.system == 'win32-msvc') def{foo}: libul{foo} if ($cxx.target.system == 'mingw32') cxx.loptions += -Wl,--export-all-symbols That is, we use the .def file generation for MSVC and the built-in support (--export-all-symbols) for MinGW. But it is also possible to use the .def file generation for MinGW. In this case we need to explicitly load the bin.def module (which should be done after loading c or cxx) and using the following setup: using bin.def # In root.build. lib{foo}: libul{foo}: {hxx cxx}{**} ... lib{foo}: def{foo}: include = ($cxx.target.class == 'windows') def{foo}: libul{foo}

2020-11-05Initial Emscripten supportBoris Kolpackov1-138/+153
- Target: wasm32-emscripten (wasm32-unknown-emscripten). - Compiler id: clang-emscripten (type clang, variant emscripten, class gcc). - Ability to build executables (.js plus .wasm) and static libraries (.a). Set executable bit on the .js file (so it can be executed with a suitable binfmt interpreter). - Default config.bin.lib for wasm32-emscripten is static instead of both. - Full C++ exception support is enable unless disabled explicitly by the user with -s DISABLE_EXCEPTION_CATCHING=1|2. - The bin module registers the wasm{} target type for wasm32-emscripten.

We were trying to be clever but GCC 10's IPA-SRA optimization didn't like it.
2020-04-27Rework tool importation along with cli moduleBoris Kolpackov1-1/+1
Specifically, now config.<tool> (like config.cli) is handled by the import machinery (it is like a shorter alias for config.import.<tool>.<tool>.exe that we already had). And the cli module now uses that instead of custom logic. This also adds support for uniform tool metadata extraction that is handled by the import machinery. As a result, a tool that follows the "build2 way" can be imported with metadata by the buildfile and/or corresponding module without any tool-specific code or brittleness associated with parsing --version or similar outputs. See the cli tool/module for details. Finally, two new flavors of the import directive are now supported: import! triggers immediate importation skipping any rule-specific logic while import? is optional import (analogous to using?). Note that optional import is always immediate. There is also the import-specific metadata attribute which can be specified for these two import flavors in order to trigger metadata importation. For example: import? [metadata] cli = cli%exe{cli} if ($cli != [null]) info "cli version $($cli:cli.version)"

2020-03-20Generate common .pc file in addition to static/staged when installing lib{}Boris Kolpackov1-1/+1
The common .pc file is produced by ignoring any static/shared-specific poptions and splitting loptions/libs into Libs/Libs.private. It is "best effort", in a sense that it's not guaranteed to be sufficient in all cases, but it will probably cover the majority of cases, even on Windows, thanks to automatic dllimport'ing of functions.
