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.

JNI is a more apt name because it currently only supports the JNI. I
also believe that CMake uses the terminology JNI here as well.
JNI is currently the only way to interact with the JVM through native
code, but there is a project called "Project Panama" which aims to be
another way for native code to interact with the JVM.
After implementing a much more extensive Java native module than what
currently exists in the tests, I found shortcomings.
1. You need to be able to pass multiple Java files.
2. Meson needs more information to better track the generated native
headers.
3. Meson wasn't tracking the header files generated from inner classes.
This new function should fix all the issues the old function had with
room to grow should more functionality need to be added. What I
implemented here in this new function is essentially what I have done in
the Heterogeneous-Memory Storage Engine's Java bindings.
When the project instals GDB helper scripts, copy them into
meson-private directory with the right tree layout and write a .gdbinit
script to load them automatically.
The documentation on how shaderc is checked in meson was quite behind.
Update it to mention that pkg-config is the default and preferred method
of checking. Also be specific about what order everything is checked in
since shaderc is confusing.
The default behavior of installing relative to prefix may be unexpected,
and is definitely wrong in many cases.
Give users control in order to specify that yes, they actually want to
install to a venv.
This is particularly useful for projects that use meson as a build
system for a python module, where *all* files shall be installed into
the python site-packages.
stdout line matching supports count since commit
66d62a224e to fail if certain output is
present (count: 0) but it was never documented in the contribution
guidelines.
Automatically generate additional variables and write them into the
generated pkg-config file.
This means projects no longer need to manually define the ones they
use, which is annoying for dataonly usages (it used to forbid setting
the base library-relevant "reserved" ones, and now allows it only for
dataonly. But it's bloat to manualy list them anyway).
It also fixes a regression in commit
248e6cf473 which caused libdir to not be
set, and to be unsettable, if the pkg-config file has no libraries but
uses the ${libdir} expansion in a custom variable. This could be
considered likely a case for dataonly, but it's not guaranteed.
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".
CMake's write_basic_package_version_file has supported since version 3.14
an ARCH_INDEPENDENT option that makes it skip its architecture check in
the Version file.
With this patch Meson now supports it as well, and the change is also
compatible with older CMake versions, as they will simply ignore the
option.
This also slightly changes the contents of the generated Version file
when arch_independent is not set: previously, the if() needed to skip
the arch check was always filled with an empty string, while CMake puts
"FALSE" (or "TRUE") in it. Now, that if() will always be filled with
either "False" or "True", better matching CMake's behaviour.
This was a nice idea in theory, but in practice it had various problems:
- On the only platform where ldconfig is expected to be run, it is
really slow, even when the user uses a non-default prefix and ldconfig
doesn't even have permission to run, nor can do anything useful due to
ld.so.conf state
- On FreeBSD, it bricked the system: #9592
- On cross builds, it should not be used and broke installing, because
ldconfig may not be runnable without binfmt + qemu: #9707
- it prints weird and confusing errors in the common "custom prefix"
layout: #9241
Some of these problems can be or have been fixed. But it's a constant
source of footguns and complaints and for something that was originally
supposed to be just "it's the right thing to do anyway, so just do it
automatically" it is entirely too risky.
Ultimately I do not think there is justification for keeping this
feature in since it doesn't actually make everyone happy. Better for
users to decide whether they need this themselves.
This is anyways the case for cmake and autotools and generally any other
build system, so it should not be too intimidating...
Fixes#9721
Regressed in commit bfb12222c3.
This needs to iterate over all methods, process them, and add them to a
list. Instead, it deleted all methods, processed all remaining methods,
and appended them to the in-use iterator.
Use a second list, instead.
Fixes#9922
Do not recommend running the 'upload' target by default in order to
build the docs. That will fail with permission errors when trying to
push to a repo most people don't have commit access to, and if they did
have commit access it would be an even worse problem -- unpredictably
overwriting the main website without any guarantee it was generated from
the latest version of the docs!
Plus, it does not actually work. The first thing it does is spawn an
error message that required files do not exist, because the actual docs
were not, in fact, built. So they cannot be uploaded either.
The docs will build by default if you do not specify a non-default
target.
Fixes#9873
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.
