intel compiler's defaults are different enough from MSVC and GNU
that it's necessary to set specific defaults for Intel compilers.
This corrects/improves behaviors initially addressed in b1c8f765fa
If a user passes -fuse-ld=gold to gcc or clang, they expect that they'll
get ld.gold, not whatever the default is. Meson currently doesn't do
that, because it doesn't pass these arguments to the linker detection
logic. This patch fixes that. Another case that this is needed is with
clang's --target option
This is a bad solution, honestly, and it would be better to use $LD or a
cross/native file but this is needed for backwards compatability.
Fixes#6057
Currently this is done at the instance level, but we need it at the
class level to allow compiler "lang" args to be gotten early enough.
This patch also removes a couple of instance of branch/leaf classes
providing their own implementation that is identical to the Compiler
version.
access(2) tests for X_OK that return true do not always guarantee that
the file is executable. Instead check the stat(2) mode bits explicitly.
This fixes any builds or installs executed as root on Solaris and
illumos that contain non-executable scripts.
Meson's documentation about cross-compilation made me finally understand
why the typical confusion about machine names. Thanks, but let's make it
even better. Don't wait until the very end of the section to reveal the
most important information: that machine names are relative. For
suspense we already have TV shows; spill the beans much earlier.
Also fix the first, simplest cross-compilation example: target is
irrelevant.
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
This default behavior can have surprising and time-consuming outcomes.
I was wondering why certain tests using several external, fixed libraries
would fail only with Meson and not with CMake or manual runs.
It turned out mtest.py enables MALLOC_PERTURB_ by default, which is
surprising--a topic for another Issue/PR.
At least, this surprising default is documented with workarounds.
wrap: add imposter URL test
this test shows that meson wrap subsystem historically allows
imposter URLs like https://wrapdb.mesonwrap.com.evil/v1/foo.zip
while the new code does no.
In my opinion, we should not fall back to http:// from the SSL HSTS WrapDB URL,
**for systems that have Python SSL** as that is controverting the point
of HSTS + SSL.
For systems that do not have Python SSL, they continue to work with a
colored mlog.warning instead of only a stderr console print.
