There are two awful things about CompilerArgs, one is that it directly
inherits from list, and there are a lot of subtle gotcahs with
inheriting from builtin types. The second is that the class allows
arguments to be passed in whatever order. That's bad. This also fully
annotates the CompilerArgs class, so mypy can type check it for us.
This dumps xild on mac and linux. After a lot of reading and banging my
head I've discovered we (meson) don't care about xild, xild is only
useful if your invoke ld directly (not through icc/icpc) and you want to
do ipo/lto/wpo. Instead just make icc report what it's actually doing,
invoking ld or ld64 (for linux and mac respectively) directly. This
allows us to get -fuse-ld working on linux.
Previously if a user tried to pass a command line build
option that contained a '%' character the command line
parser assumed that there was string interpolation to be
done. As there is no sense in such a scenario no code
provides any input for the interpolation. This then leads to
a failure.
In this commit we specifically override the defaults in
ConfigParser and set interpolation to None, which disables
command line build option interpolation.
Fixes#6157
A build with a cross file should always be identified as a cross build, even if
the host and build machine are identical. This was the case in 0.50, regressed
in 0.51, and is fixed again in 0.52, so add a test case to ensure it doesn't
regress again.
Now that the linkers are split out of the compilers this enum is
only used to know what platform we're compiling for. Which is
what the MachineInfo class is for
test3-static was actually always using the shared library because that
warning was not fatal:
WARNING: Static library 'func6' not found for dependency 'func6', may
not be statically linked
The reason why the libfunc6.a wasn't found is because the prefix in the
generated pc file was not set to install dir.
In qemu, minikconf generates a depfile that meson could use to
automatically reconfigure on dependency change.
Note: someone clever can perhaps find a way to express this with a
ninja rule & depfile=. I didn't manage, so I wrote a simple depfile
parser.
According to http://testanything.org/tap-specification.html
"Any output line that is not a version, a plan, a test line, a
diagnostic or a bail out is considered an “unknown” line. A TAP parser
is required to not consider an unknown line as an error but may
optionally choose to capture said line and hand it to the test
harness, which may have custom behavior attached [...] TAP::Harness
reports TAP syntax errors at the end of a test run".
(glib gtest can generate empty lines)
The main library must come before extra libraries, because they are
likely to be dependencies of the main library that get promoted from
private to public. This was causing static link issues with glib-2.0.pc.
On illumos (and presumably Solaris, though I can't test) cc normally
points to Sun CC, which we don't support. So ensure that gcc is used
explicitly in that case.
* Do not strip static archives
Stripping static archives without more fine-grained options (e.g. `-g`)
leads to failures such as
ld: libfoo.a: error adding symbols: archive has no index; run ranlib to add one
because GNU strip removes *every* symbol in a static archive by default.
Given that static archives are not final build artifacts (unlike
executables and shared libraries), stripping them gains little and only
causes more edge case failures.
* Gentoo's portage only strips debug information:
86f211e3a5/bin/estrip (L322)
* Fedora also only strips debug information:
e9c13c6565/scripts/brp-strip-static-archive (L18)
* Debian also only does some very light stripping:
72ed1d3261/dh_strip (L374)Fixes#4138
* Add test case for static archive stripping
Instead of the DynamicLinker returning a hardcoded value like
`-Wl,-foo`, it now is passed a value that could be '-Wl,', or could be
something '-Xlinker='
This makes a few things cleaner, and will make it possible to fix using
clang (not clang-cl) on windows, where it invokes either link.exe or
lld-link.exe instead of a gnu-ld compatible linker.
Clang doesn't really like having no-undefined plus the address sanitizer, but
gcc doesn't mind. This all happens to work with clang + gnu ld, but with clang
+ apple ld this turns into a dumpster fire. Just add b_lundef=false to make
everyone happy.
