Instead use coredata.compiler_options.<machine>. This brings the cross
and native code paths closer together, since both now use that.
Command line options are interpreted just as before, for backwards
compatibility. This does introduce some funny conditionals. In the
future, I'd like to change the interpretation of command line options so
- The logic is cross-agnostic, i.e. there are no conditions affected by
`is_cross_build()`.
- Compiler args for both the build and host machines can always be
controlled by the command line.
- Compiler args for both machines can always be controlled separately.
When building for iOS, the Qt binaries only contain static libraries
and headers. No framework.
With this, Meson can successfully compile and link to Qt on iOS
macOS provides the tool `lipo` to check the archs supported by an
object (executable, static library, dylib, etc). This is especially
useful for fat archives, but it also helps with thin archives.
Without this, the linker will fail to link to the library we mistakenly
'found' like so:
ld: warning: ignoring file /path/to/libfoo.a, missing required architecture armv7 in file /path/to/libfoo.a
Instead of only doing a naive filesystem search, also run the linker
so that it can tell us whether the -F path specified actually contains
the framework we're looking for.
Unfortunately, `extraframework` searching is still not 100% correct in
the case when since we want to search in either /Library/Frameworks or
in /System/Library/Frameworks but not in both. The -Z flag disables
searching in those prefixes and would in theory allow this, but then
you cannot force the linker to look in those by manually adding -F
args, so that doesn't work.
Also add a test for it. In the process, also remove an overly-zealous
try..except statement that was catching *all* exceptions, not just
expected ones, which was masking programming errors.
.get_command() will return None when it's not found, so there's no
point trying to print that. Print self.name instead, which is what
we tried to search for.
Fixes this annoying warning while running the tests:
mesonbuild/coredata.py:237: DeprecationWarning: The SafeConfigParser
class has been renamed to ConfigParser in Python 3.2. This alias will be
removed in future versions. Use ConfigParser directly instead.
When using pkg.generate(mylib, library : publicdep) it is pretty clear
we don't want to associate publicdep to this generated pkg-config file.
This is a small behaviour break in theory, but also fixes real bug in
the case publicdep is later used to generate another pkg-config file
that does not depend on mylib, that would write a wrong `Requires:
mylib` in the genarated pkg-config file.
This fix unavoidable deprecation warning when glib is cross built
for Android. Glib does `pkg.generate(libglib, libraries : [libintl],
...)` which wrongly associates libintl to the generated glib-2.0.pc, so
when later it generates gio-2.0.pc file that depends on libglib, it will
warn about libintl being associated with libglib. This does not happen
in normal glib build because libintl is usually provided by glibc and is
only an internal library when it fallbacks to a subproject.
This is the second most straight forward stupid way of handling
this (with usiing os.path.exists) as the most stupid obvious way. The
only major advantage is that having .git as something other than a
file or directory still doesn't register.
Fixes: #3378
First, I noticed there was a dangling use of now-removed cross_info in
the CMake lookup. No tests had caught this, but it means that CMake deps
were totally broken. [It also meant that CMake could not be specified
from a native file.]
In a previous of mine PR which removed cross_info, I overhauled finding
pkg-config a bit so that the native and cross paths were shared. I
noticed that the CMake code greatly resembled the pkg-config code, so I
set about fixing it to match.
I then realized I could refactor things further, separating caching,
finding alternatives, and validating them, while also making the
validations less duplicated. So I ended up changing pkg config lookup a
lot too (and CMake again, to keep matching).
Overall, I think I have the proper ideom for tool lookup now, repated in
two places. I think it would make sense next to share this logic between
these two, compilers, static linkers, and any other tool similarly
specifiable. Either the `BinaryTable` class in environment.py, or a new
class for `Compiler` and friends to subclass, would be good candidates
for this.
