2019-11-04Add support for configuration exporting and importingBoris Kolpackov1-1/+31
The new config.export variable specifies the alternative file to write the configuration to as part of the configure meta-operation. For example: $ b configure: proj/ config.export=proj-config.build The config.export value "applies" only to the projects on whose root scope it is specified or if it is a global override (the latter is a bit iffy but we allow it, for example, to dump everything to stdout). This means that in order to save a subproject's configuration we will have to use a scope-specific override (since the default will apply to the outermost amalgamation). For example: $ b configure: subproj/ subproj/config.export=.../subproj-config.build This could be somewhat unnatural but then it will be the amalgamation whose configuration we normally want to export. The new config.import variable specifies additional configuration files to be loaded after the project's default config.build, if any. For example: $ b create: cfg/,cc config.import=my-config.build Similar to config.export, the config.import value "applies" only to the project on whose root scope it is specified or if it is a global override. This allows the use of the standard override "positioning" machinery (i.e., where the override applies) to decide where the extra configuration files are loaded. The resulting semantics is quite natural and consistent with command line variable overrides, for example: $ b config.import=.../config.build # outermost amalgamation $ b ./config.import=.../config.build # this project $ b !config.import=.../config.build # every project Both config.export and config.import recognize the special `-` file name as an instruction to write/read to/from stdout/stdin, respectively. For example: $ b configure: src-prj/ config.export=- | b configure: dst-prj/ config.import=-
2019-10-18Add ability to specify "compiler mode" options as part of config.{c,cxx}Boris Kolpackov1-6/+10
Such options are (normally) not overridden by buildfiles and are passed last (after cc.coptions and {c,cxx}.coptions) in the resulting command lines. They are also cross-hinted between config.c and config.cxx. For example: $ b config.cxx="g++ -m64"
2019-10-16Try to find MSVC installation for absolute cl.exe pathsBoris Kolpackov1-1/+9
Without this extra logic recursive invocation of the build system (e.g., in tests) will fail to obtain the full environment.
2019-10-14Implement MSVC installation discovery for version 15 (2017) and laterKaren Arutyunov1-3/+3
In particular, this removes the requirement to build from the Visual Studio command prompt. Note that since MSVC compiler binaries are target-specific (i.e., there are no -m32/-m64 options nor something like /MACHINE), in this case we default to a 64-bit build (a 32-bit build can still be achieved by running from a suitable command prompt). Finally, this mechanism is also used to find Clang bundled with MSVC.
2019-10-08Redo bin pattern as PATH-like search paths rather than fallback directoryBoris Kolpackov1-10/+12
Also, unlike the fallback directory, the search paths are searched first rather than last.
2019-10-01Adapt to renaming butl::casecmp() to icasecmp()Karen Arutyunov1-8/+8
