Previously, the configuration worked fine, but the compiler raised an
error. Now, we explicitly check for the existence of files and print a
useful error message if they do not exist.
With this it is now possible to do
foobar = executable('foobar', ...)
meson.override_find_program('foobar', foobar)
Which is convenient for a project like protobuf which produces both a
dependency and a tool. If protobuf is updated to use
override_find_program, it can be used as
protobuf_dep = dependency('protobuf', version : '>=3.3.1',
fallback : ['protobuf', 'protobuf_dep'])
protoc_prog = find_program('protoc')
Refine #3277
According to what I read on the internet, on OSX, both MH_BUNDLE (module)
and MH_DYLIB (shared library) can be dynamically loaded using dlopen(), but
it is not possible to link against MH_BUNDLE as if they were shared
libraries.
Metion this as an issue in the documentation.
Emitting a warning, and then going on to fail during the build with
mysterious errors in symbolextractor isn't very helpful, so make attempting
this an error on OSX.
Add a test for that.

That syntax is invalid, since decimal numbers should never have a
leading zero and octal numbers use the `0o` prefix instead.
This matches Python 3 syntax which does not accept it:
$ python3
>>> 0123
File "<stdin>", line 1
0123
^
SyntaxError: invalid token
>>>
Add a "failing" test case to confirm this property is preserved and no
regressions are introduced in this area.
This will copy the file to the build directory without trying to read
it or substitute values into it.
Also do this optimization if the configuration_data() object passed to
the `configuration:` kwarg is empty, and print a warning about it.

With executable(), if the link_with argument has a string as one of it's
elements, meson ends up throwing an AttributeError exception:
...
File "/home/lyudess/Projects/meson/mesonbuild/build.py", line 868, in link
if not t.is_linkable_target():
AttributeError: 'str' object has no attribute 'is_linkable_target'
Which is not very helpful in figuring out where exactly the project is
trying to link against a string instead of an actual link target. So,
fix this by verifying in BuildTarget.link() that each given target is
actually a Target object and not something else.
Additionally, add a simple test case for this in failing tests. At the
moment, this test case just passes unconditionally due to meson throwing
the AttributeError exception and failing as expected. However, this test
case will be useful eventually if we ever end up making failing tests
more strict about failing gracefully (per advice of QuLogic).
I've typo'd "value" for the last time, options needs a kwargs validator.
This validator is slightly different than the one used by the main
parser, since it operates on a much simpler representation than the
other one does, and they are not interchangeable.
This also changes the optinterpreter to use pop on 'type' and
'description' so that they're not passed to the validator as kwargs.
This allows a CustomTarget to be indexed, and the resulting indexed
value (a CustomTargetIndex type), to be used as a source in other
targets. This will confer a dependency on the original target, but only
inserts the source file returning by index the original target's
outputs. This can allow a CustomTarget that creates both a header and a
code file to have it's outputs split, for example.
Fixes#1470
Add a boolean 'implib' kwarg to executable(). If true, it is permitted to
use the returned build target object in link_with:
On platforms where this makes sense (e.g. Windows), an implib is generated
for the executable and used when linking. Otherwise, it has no effect.
(Rather than checking if it is a StaticLibrary or SharedLibary, BuildTarget
subclasses gain the is_linkable_target method to test if they can appear in
link_with:)
Also install any executable implib in a similar way to a shared library
implib, i.e. placing the implib in the appropriate place
Add tests of:
- a shared_module containing a reference to a symbol which is known (at link
time) to be provided by the executable
- trying to link with non-implib executables (should fail)
- installing the implib
(This last one needs a little enhancement of the installed file checking as
this is the first install test we have which needs to work with either
MSVC-style or GCC-style implib filenames)
