This code isn't used as present: the actual objects we use and which get
pickled are either static subclasses of ConfigToolDependency, or special
purpos subclasses of Dependency which get attributes copied from an instance
of a dynamic subclass of ConfigToolDependency which is then discarded.
This is fortunate, as it doesn't work: the pickled reduction is a call to
the dynamic subclass's constructor, but the superclass constructors rely on
the environment object being fully initialized, which hasn't happened yet
during unpickling.
Avoid this by having a pickled reduction which is just a call to create the
dynamic subclass object, and relying on the default __setstate__ behavior to
unpickle the object's __dict__.
Since this is only consulted while constructing the Dependency object, it's
result doesn't depend on the instance (and it would make no sense if it did)
The output may be a binary data stream, not subject to any locale
encoding. This avoids any encoding errors that might arise as a result.
Also fixes github issue #2868.
This is important so people can not trick Meson to select a
subproject_dir that is not in the project's source directory.
It also ensures a string is used for the path.
They now are published by the D Language Foundation, and not Digital
Mars. Therefore, their signature has changed slightly.
(We can not check for 'DMD', because that string appears in every
compiler version output to denote the frontend version used by the
compiler).
The previous change disallowed any subdirectories for subproject dirs,
and therefore broke a couple of projects making use of that.
This change still prevents people from setting subproject dirs that are
not in the project's source tree, while allowing to specify any path
within the project's directory again.
Resolves: #2719
Because FreeBSD's llvm-config adds -l/usr/lib/libexecinfo.so when asked
for system-libs, which is bogus. We'll remove the leading -l from any
argument that also ends with .so.
gnome.gtkdoc uses -Wl,-rpath to ensure the scanner executable built by
gtkdoc-scangobj will load shared libraries from the correct directories.
However, FreeBSD configures its linker to use --enable-new-dtags by
default, which converts RPATH to RUNPATH. If users have LD_LIBRARY_PATH
environment variable set, RUNPATH will be overrided by LD_LIBRARY_PATH
and libraries will be loaded from wrong directories, causing undefined
symbol error when running the executable.
In order to solve the problem, we have to prepend directories specified
with -Wl,-rpath to LD_LIBRARY_PATH to avoid relying on the deprecated
RPATH attribute.
The reason for this change is the same as the previous commit. Although
g-ir-scanner can pick arguments from CFLAGS, CPPFLAGS, LDFLAGS
environment variables by itself, it is still better for build systems
to put them on the command line instead of relying on users to setup
the same environment.
Since g-ir-scanner doesn't provide a way to set arbitrary linker flags
on the command line, arguments in LDFLAGS that are not started with -L
are not passed.
GLib-based libraries and applications require gettext library to compile
and link. On non-GNU systems such as FreeBSD, gettext is not included in
libc and it is required to pass '-L/usr/local/lib -lintl' to the linker
to satisfy the dependency on gettext. The pkg-config file provided by
GLib already has '-lintl', but users still have to remember to put
'-L/usr/local/lib' into LDFLAGS. If we don't pass LDFLAGS to
gtkdoc-scangobj, the linker will not be able to find '-lintl' when no
dependencies of the project provides '-L/usr/local/lib'.
Since all *FLAGS are commonly used in many build systems, this commit
adds support for not only LDFLAGS but also CFLAGS and CPPFLAGS.
Fixes#1724
teach detect_meson_py_location() that meson.py is not the
only one meson executable (there's wraptool + legacy scripts)
that could be installed to the PATH folder
fixes#2810
This already reports the location (in a slightly different format), but
using mlog.warning() will make it easier if we want to change the location
format in future.
