This further simplifies behavior to match the "build vs host" decision
we did with `c_args` vs `build_c_args`. The rules are now simply:
- `native: true` affects `native: true` targets
- `native: false` affects `native: false` targets
- No native flag is the same as `native: false`
I like this because you don't even have to know what "build" and "host"
mean to understand how it works, and it doesn't depend on whether the
overall build is cross or not.
Fixes#4933
In some cases it may be necessary to set PKG_CONFIG_SYSROOT_DIR, like
when you've mounted a host architecture system in an arbitrary path.
Meson will now check the cross files for a [properties]:sys_root
variable and set the PKG_CONFIG_SYSROOT_DIR environment variable based
on that variable.
Fixes#3801Fixes#4057
* c_function_attributes: remove 'protected' from 'visibility'
This doesn't exist on macos with the apple compiler, which always causes
failures.
Fixes#5530
* compilers: Add split visibility checks to has_function_attribute
These check for a single visibility at a time, rather than all four at
once. This allows for finer grained searches, and should make using
these checks safer across operating systems.
* coredata: Correctly handle receiving a pipe for native/cross files
In some cases a cross/native file may be a pipe, such as when using bash
process replacement `meson --native-file
<([binaries]llvm-config='/opt/bin/llvm-config')`, for example. In this
case we copy the contents of the pipe into a file in the meson-private
directory so we can create a proper ninja dependency, and be able to
reload the file on --wipe/--reconfigure. This requires some extra
negotiation to preserve these native/cross files.
Fixes#5505
* run_unitests: Add a unit test for native files that are pipes
Using mkfifo.
We were setting the base options for the Objective-C compiler
manually, due to which options such as b_bitcode and b_ndebug were not
getting set at all.
The base options here are the same as for C code with the Clang
compiler, so just use the same inherited list.
Also expand the bitcode test to ObjC and ObjC++ so this doesn't happen
again.
