t.pic won't be defined. We can only hope it has been built with -fPIC.
Linker will complain otherwise any way.
t.extract_all_objects_recurse() won't be defined. We could support this
case by extracting the archive somewhere and pick object files.
Refactor the code inside a common function for consistency.
It's not needed to add dependencies in func_configure_file() because
it's already done in run_command_impl(). Do it only for files from
`input:` in the case some of them does not end up in the command
arguments.
We might be using the 32-bit bits of the VulkanSDK on Windows on x64
Windows, so we still need to pass in the compiler items to detect what
architecture we are building for, so that we link to the correct Vulkan
libraries.
We might want to look into this again if Microsoft will allow ARM/ARM64
versions of the Vulkan drivers and SDK, since post-basic OpenGL and
any Vulkan are not supported on Windows-on-ARM.
* Have set() and set_quoted() of configuration object work with newlines.
set_quoted() makes the value into a double-quoted string, so let's
assume C-style string, in particular with newlines as "\n".
Also take care of remaining newlines in dump_conf_header(). C or nasm
macros expect single-line values so if the value was multi-line, we
would end up with broken syntax. Appending a backslash at each end of
line make them concat into a single line in both C and nasm format
(note: multi-line macros in nasm are actually possible apparently but
use another format not outputted by current meson code). Also note that
the replacement is done at the end only when dumping the conf as a
header because we cannot assume anything about the format when replacing
variables from an input file (in this case, it should be the dev
responsibility).
* Add unit tests for multiline set() and set_quoted().
Instead of only displaying the identifier of the linker, display also the path
to the executable in order to report useful information when cross-compiling.
Since version 9.1, GCC provides support for the D programming language. Thus it
is easy to build a cross-compiler for D, such as aarch64-unknown-linux-gnu-gdc.
However to cross-compile a Meson project using D, using a cross build definition
such as the following is not enough:
```
[binaries]
d = '/path/to/aarch64-unknown-linux-gnu-gdc'
exe_wrapper = '/path/to/qemu-aarch64-static'
[properties]
needs_exe_wrapper = true
[host_machine]
system = 'linux'
cpu_family = 'aarch64'
cpu = 'cortex-a53'
endian = 'little'
```
Indeed, "exe_wrapper" is not be taken into account. Build will fail with:
```
Executables created by D compiler /path/to/aarch64-uknown-linux-gnu-gdc are not runnable.
```
This patch fixes this by reworking:
- detect_d_compiler() to properly get exe_wrapper and D compilers and detect the
one available.
- Dcompiler to properly handle exe_wrapper.
It would be very challenging if not futile to make has_function work for Fortran.
The meson.get_compiler('fortran').links() works very well instead.
As a reference, CMake's check_fortran_function_exists is completely broken in general.
This change raises a useful MesonException instead of giving bizarre errors.
Some commands, notably gdb, use ctrl+c themselves to perform actions
without exiting. Instead of making meson exit and thus, kill the
subprocess, ignore the KeyboardInterrupt and continue waiting for
the child.
