Remove --debug-incremental
This flag is also added to the build system. Importantly, this tells
Compile step whether or not to keep the compiler running between
rebuilds. It defaults off because it is currently crashing
zirUpdateRefs.
Changes the `make` function signature to take an options struct, which
additionally includes `watch: bool`. I intentionally am not exposing
this information to configure phase logic.
Also adds global zig cache to the compiler cache prefixes.
Closes#20600
This allows running commands that take an output directory argument. The
main thing that was needed for this feature was generated file subpaths,
to allow access to the files in a generated directory. Additionally, a
minor change was required to so that the correct directory is created
for output directory args.
* `doc/langref` formatting
* upgrade `.{ .path = "..." }` to `b.path("...")`
* avoid using arguments named `self`
* make `Build.Step.Id` usage more consistent
* add `Build.pathResolve`
* use `pathJoin` and `pathResolve` everywhere
* make sure `Build.LazyPath.getPath2` returns an absolute path
writeFile was deprecated in favor of writeFile2 in f645022d16361865e24582d28f1e62312fbc73bb. This commit renames writeFile2 to writeFile and makes writeFile2 a compile error.
Adds an `include_paths` field to RcSourceFile that takes a slice of LazyPaths. The paths are resolved and subsequently appended to the -rcflags as `/I <resolved path>`.
This fixes an accidental regression from https://github.com/ziglang/zig/pull/19174. Before that PR, all Win32 resource compilation would inherit the CC flags (via `addCCArgs`), which included things like include directories. After that PR, though, that is no longer the case.
However, this commit intentionally does not restore the previous behavior (inheriting the C include paths). Instead, each .rc file will need to have its include paths specified directly and the include paths only apply to one particular resource script. This allows more fine-grained control and has less potentially surprising behavior (at the cost of some convenience).
Closes#19605
Windows does not support RPATH and only searches for DLLs in a small
number of predetermined paths by default, with one of them being the
directory from which the application loaded.
Installing both executables and DLLs to `bin/` by default helps ensure
that the executable can find any DLL artifacts it has linked to.
DLL import libraries are still installed to `lib/`.
These defaults match CMake's behavior.
This is a partial revert of 105db13536b4dc2affe130cb8d2eee6c97c89bcd.
As we learned from Void Linux packaging, these options are not actually
helpful since the distribution package manager may very well want to
cross-compile the packages that it is building.
So, let's not overcomplicate things. There are already the standard
options: -Dtarget, -Dcpu, and -Ddynamic-linker.
These options are generally provided when the project generates machine
code artifacts, however, there may be a project that does no such thing,
in which case it makes sense for these options to be missing. The Zig
Build System is a general-purpose build system, after all.
This adds the *std.Build owner to LazyPath so that lazy paths returned
from a dependency can be used in the application without friction or
footguns.
closes#19313
Previously, `Step.Compile.installHeader` and friends would incorrectly
modify the default `install` top-level step, when the intent was for
headers to get bundled with and installed alongside an artifact. This
change set implements the intended behavior.
This carries with it some breaking changes; `installHeader` and
`installConfigHeader` both have new signatures, and
`installHeadersDirectory` and `installHeadersDirectoryOptions` have been
merged into `installHeaders`.
* make test names contain the fully qualified name
* make test filters match the fully qualified name
* allow multiple test filters, where a test is skipped if it does not
match any of the specified filters
This also makes a long-overdue change of extracting common state from
Build into a shared Graph object.
Getting the semantics right for these flags turned out to be quite
tricky. In the end it works like this:
* The override only happens when the target is fully native, with no
additional query parameters, such as versions or CPU features added.
* The override affects the resolved Target but leaves the original Query
unmodified.
* The "is native?" detection logic operates on the original, unmodified
query. This makes it possible to provide invalid host target
information, causing confusing errors to occur. Don't do that.
There are some minor breaking changes to std.Build API such as the fact
that `b.zig_exe` is now moved to `b.graph.zig_exe`, as well as a handful
of other similar flags.
Closes#18628
This commit splits the arguments obtained from pkg-config into two
groups, cflags and libs, and consistently applies the cflags to each
individual module linking the library while applying the libs only once
for each compilation.
Uses the new `-M[name][=src]` CLI syntax to omit the source when the
module does not have a zig root source file.
Only some kinds of link objects imply that this should happen.

This isn't technically needed since per-module -I args can suffice, but
this can produce very long CLI invocations when several --mod args are
combined with --search-prefix args since the -I args have to be repeated
for each module.
This is a partial revert of ecbe8bbf2df2ed4d473efbc32e0b6d7091fba76f.
This change is seemingly insignificant but I actually agonized over this
for three days. Some other things I considered:
* (status quo in master branch) make Compile step creation functions
accept a Target.Query and delete the ResolvedTarget struct.
- downside: redundantly resolve target queries many times
* same as before but additionally add a hash map to cache target query
resolutions.
- downside: now there is a hash map that doesn't actually need to
exist, just to make the API more ergonomic.
* add is_native_os and is_native_abi fields to std.Target and use it
directly as the result of resolving a target query.
- downside: they really don't belong there. They would be available
as comptime booleans via `@import("builtin")` but they should not
be exposed that way.
With this change the downsides are:
* the option name of addExecutable and friends is `target` instead of
`resolved_target` matching the type name.
- upside: this does not break compatibility with existing build
scripts
* you likely end up seeing `target.result.cpu.arch` rather than
`target.cpu.arch`.
- upside: this is an improvement over `target.target.cpu.arch` which
it was before this commit.
- downside: `b.host.target` is now `b.host.result`.
