2022-04-06Add support for rule hintsBoris Kolpackov1-4/+2
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.
2021-10-11Update bin.lib.version documentationBoris Kolpackov1-3/+0
2021-06-30Move symbol exporting .def file rule to bin.def module, add support for MinGWBoris Kolpackov1-16/+34
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}

2020-11-06Keep executable bit on .wasm files when installingBoris Kolpackov1-2/+4
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.

2020-06-16Add $bin.link_member() functionBoris Kolpackov1-2/+14
Given a linker output target type ("exe", "lib[as]", or "libu[eas]") return the target type of lib{} group member ("liba" or "libs") that will be picked when linking a lib{} group to this target type.

2020-05-22Make template definition available in all translation units where usedBoris Kolpackov1-1/+1
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)"

Note that this only manifests itself when compiling in the C++14 mode (e.g., during bootstrap or with an older compiler like GCC 4.9).
