2024-08-06Add support for specifying compile options on exe/lib{} targetsBoris Kolpackov2-38/+354
It is now possible to specify compile option (*.poptions and *.coptions) on the exe/lib{} targets (we call them "binary-specific compile options"). Such options are propagated to obj/bmi{} targets that are synthesized for source prerequisites of the binary. Note that this propagation does not apply to obj/bmi{} prerequisites. For example: exe{foo}: cxx{foo} obj{common} { cxx.poptions += -DFOO } exe{bar}: cxx{bar} obj{common} { cxx.poptions += -DBAR } obj{common}: cxx{common} { cxx.poptions += -DCOMMON } In this example, cxx{foo} will be compiled with -DFOO, cxx{bar} -- with -DBAR, and cxx{common} -- with -DCOMMON. Note that if a source prerequisite is shared between several binaries, then the values of the propagated compile options (or their absence) must match. For instance, the following variant of the above example would result in an error since cxx{common} would have contradictory cxx.poptions values: exe{foo}: cxx{foo common} { cxx.poptions += -DFOO } exe{bar}: cxx{bar common} { cxx.poptions += -DBAR } As another example, here is how we can rewrite a typical library buildfile (which requires different macros to distinguish between shared/static builds) using this mechanism, in this case, to build two libraries in the same scope: ./: lib{foo}: {hxx cxx}{*-foo} ./: lib{bar}: {hxx cxx}{*-bar} cxx.poptions =+ "-I$out_root" "-I$src_root" lib{foo}: { cxx.poptions += -DFOO cxx.export.poptions = "-I$out_root" "-I$src_root" } liba{foo}: { cxx.poptions += -DLIBFOO_STATIC_BUILD cxx.export.poptions += -DLIBFOO_STATIC } libs{foo}: { cxx.poptions += -DLIBFOO_SHARED_BUILD cxx.export.poptions += -DLIBFOO_SHARED } lib{bar}: { cxx.poptions += -DBAR cxx.export.poptions = "-I$out_root" "-I$src_root" } liba{bar}: { cxx.poptions += -DLIBBAR_STATIC_BUILD cxx.export.poptions += -DLIBBAR_STATIC } libs{bar}: { cxx.poptions += -DLIBBAR_SHARED_BUILD cxx.export.poptions += -DLIBBAR_SHARED } The exact semantics of this mechanism is as-if the binary-specific compile options were set on the synthesized obj/bmi{} targets at the end of the buildfile. One nuance to keep in mind is that target type/pattern-specific assign/append/prepend specified for obj/bmi{} will not be in effect for options specified on lib/exe{}. For example: cxx.poptions += -DSCOPE obj{*}: cxx.poptions += -DTARGET exe{foo}: cxx.poptions += -DFOO Here the effective cxx.poptions for exe{foo} prerequisites will be -DSCOPE -DFOO since exe{foo} does not match the obj{*} pattern. As result, if using this mechanism, remember to include the binary target types in obj{} patterns. For example: {obj exe}{*}: cxx.poptions += -DTARGET

2024-05-09Fixes and tweaks to diagnostics color support on Windows (GH issue #312)Boris Kolpackov1-1/+13
Specifically: - Pass -fansi-escape-codes for Clang on Windows. - Enable diagnostics color by default if already enabled on the terminal. Only try to enable it ourselves with explicit --diag-color.

2024-02-26Add ability to serialize compilation/linking in cc rulesBoris Kolpackov4-8/+43
Specifically, both the C/C++ compiler and link rules now recognize the cc.serialize boolean variable which instructs them to compiler/link serially with regards to any other recipe. This is primarily useful when compiling large translation units or linking large binaries that require so much memory that doing that in parallel with other compilation/linking jobs is likely to summon the OOM killer. For example: obj{memory-hog}: cc.serialize = true

2024-01-10Add ability to specify alternative sysroot for pkg-config files (GC issue #59)Boris Kolpackov2-4/+65
Specifically, the new config.cc.pkgconfig.sysroot variable provides roughly equivalent functionality to PKG_CONFIG_SYSROOT_DIR in pkg-config. For details and limitations, see "Rewriting Installed Libraries System Root (sysroot)" in the manual for details.
2024-01-10Fix bunch of typosBoris Kolpackov4-6/+6
2024-01-09Disable use of -frewrite-includes for assembler with preprocessor filesBoris Kolpackov1-3/+24
With -frewrite-includes Clang has issues with correctly tracking location information (manifests itself as wrong line numbers in debug info, for example). The result also appears to reference the .Si file instead of the original source file for some reason. While at it also omit trying to scan such files since that can be hazardous (such files sometimes use `#`-style comments).
2024-01-08Allow specifying compiler mode options in buildfileBoris Kolpackov1-7/+20
Now the configured mode options are appended to buildfile-specified (which must be specified before loading the guess module). In particular, this ability to specify the compiler mode in a buildfile is useful in embedded development where the project may need to hardcode things like -target, -nostdinc, etc. For example: cxx.std = 20 cxx.mode = -target riscv32-unknown-unknown -nostdinc using cxx
