With GCC 10, -fno-common becomes default behavior, meaning that any
subtly-broken code will be broken not so subtly anymore.
This commit changes the linkage to variables declared in headers to
external and, where needed, adds additional definitions in other
compilation units.
* xenial doesn't ship many dependencies, so make them all optional
since we don't guarantee that everything will work
* cmake/{5,6}: needs stdlib.h for EXIT_SUCCESS on GCC 5
* common/222: needs C++11, and GCC 5 doesn't understand `auto`
correctly unless we explicitly enable it.
* frameworks/1 boost: xenial doesn't ship boost_python3, so make it
properly optional
* frameworks/6 gettext: gettext can be installed without xgettext,
which doesn't cause the project to fail, but the installed files
list is different which causes the test to fail.
* frameworks/7 gnome: gobject-introspection can't be enabled because
the sanitizer unit test detects leaks in glib and fails
The pefile module is a CI dependency now, so we can use that instead
of objdump/dumpbin which greatly simplifies the test. Of course, this
module is also cross-platform so it will work if we add cross-win32 CI
at some point.
Make the 'framework/4 qt' test more flexible about what version of Qt is
expected to be present in the CI environment. Currently, this is
hard-coded as Qt5. We add an option to specify it so we can run this
test under CI with just Qt4 present.
fixes#6096.
Didn't use CMake because Curses is a real corner-case for CMake that
would require Curses-specific enhancements to Meson's CMake interface.
declare_dependencies
This allows dependencies declared in subprojects to set variables, and
for those variables to be accessed via the get_variable method, just
like those from pkg-config and cmake. This makes it easier to use
projects from subprojects in a polymorphic manner, lowering the
distinction between a subproject and an external dependency every
further.
This fixes an issue with generated sources and object libraries, as
well as an issue on windows with the `link` linker and the vs backend.
The last issue is resolved by building the source files multiple times
to avoid extracting object files in meson.
this can be useful for if/elif where linker behaviors must be
considered.
For example, clang with "link" vs gcc with "ld.bfd" etc.

is_samepath better reflects the nature of this function--that files
and directories can be compared.
Also, instead of raising exceptions, simply return False when one
or both .is_samepath(path1, path1) don't exist. This is more
intuitive behavior and avoids having an extra if fs.exist() to go
with every fs.is_samepath()
cmake: get language from Meson project if not specified as depedency(..., langugage: ...)
deps: add threads method:cmake
dependency('threads', method: 'cmake') is useful for cmake unit tests
or those who just want to find threads using cmake.
cmake: project(... Fortran) generally also requires C language
