It makes no sense to specify both:
- install_dir, which overrides the -Dincludedir= builtin option
- subdir, which suffixes the -Dincludedir= builtin option
We've always silently ignored the subdir in this case, which is really
surprising if someone actually passed it and expected it to do
something. We also confusingly didn't say anything in the documentation
about it.
Document that the options are incompatible, and explicitly check to see
if they are both passed -- if so, raise an error message pointing out
that only install_dir should be used.
Fixes#10046
Android requires shared modules that use symbols from other shared
modules to be linked before they can be dlopen()ed in the correct
order. Not doing so leads to a missing symbol error:
https://github.com/android/ndk/issues/201
We need to always allow linking for this. Also add a soname, although
it's not confirmed that it's needed, and it doesn't really hurt if it
isn't needed.
This bring us in line with Autotools and CMake and it is useful
for platforms like Nix, which install projects
into multiple independent prefixes.
As a consequence, `get_option` might return absolute paths for some
directory options, if a directory outside of prefix is passed.
This is technically a backwards incompatible change but its effect
should be minimal, thanks to widespread use of `join_paths`/`/` operator
and pkg-config generator module. It should only cause an issue when
a path were constructed by concatenating the value of directory path option.
Also remove a comment about commonpath since we do not use that since
<00f5dadd5b>.

The array of licenses is not clear, where and SPDX expression using AND
and OR is very clear, take for example this: `['Apache', 'GPLv2']`. What
does that mean? Any Apache license you like and GPLv2? Using a valid
SPDX license identifier however makes it extremely clear what is meant:
`'Apache-2.0 OR GPL-2.0-only'`. It is very clear that you mean, "this is
Apache 2.0, however, you can use as GPL-2.0 for the purpose of linking
it into your GPL-2.0 project".
This is currently allowed, and is used in at least a few projects. It
was not intended to work or documented, but it does and since it is in
use a full deprecation period must be used. A warning has also been
added for values < 0, which have surprising behavior.
They claimed that all of these functions accepted any posargs or varargs
that install scripts supported. This was inconsistent with both the
types that meson currently allowed, and the types that we documented in
refman 1.0 *should* be allowed.
Take the opportuninty to be clear as refman 1.0 never was, about the
difference between types supported in the first posarg, and the ypes
supported in succeeding varargs.
Emit a detailed deprecation warning that explains what to do instead.
Also add a unittest.
```
DEPRECATION: target prog links against shared module mymod, which is incorrect.
This will be an error in the future, so please use shared_library() for mymod instead.
If shared_module() was used for mymod because it has references to undefined symbols,
use shared_libary() with `override_options: ['b_lundef=false']` instead.
```

All kwargs inherited from has_header need to be prefixed `header_` so we
cannot just do straight inheritance. And the part of the description
that highlighted the way kwargs are derived and evolved, went entirely
missing.
Fixes#9551
It has always been working even if not documented and there is no reason
to not accept it. However, change "True/False" to "true/false" to be
consistent with meson language.
Fixes: #9436
This replaces the absolute hack of using
```
install_subdir('nonexisting', install_dir: 'share')
```
which requires you to make sure you don't accidentally or deliberately
have a completely different directory with the same name in your source
tree that is full of files you don't want installed. It also avoids
splitting the name in two and listing them in the wrong order.
You can also set the install mode of each directory component by listing
them one at a time in order, and in fact create nested structures at
all.
Fixes#1604
Properly fixes#2904
In the refman rewrite, these functions vanished. I noticed this when I
went looking at the docs for extract_all_objects(), or should I say I
tried to go looking.
