By suggestion of Alexander I have tried to change recipes known to use meson
My results are mixed.
With libinput the test was skipped automatically
With libepoxy there were no tests defined.
With json-glib I can run 13/14 tests successfully. One of the tests
exits with a segmentation fault and I cannot know if it is qemu giving
the ghost or a real code bug. Given that the 13 of 14 tests pass
successfully I find that the risk of misconfiguration on my part is
reduced. Because many heads think better than 1 or even 2 I leave here
the result logs of the failing test: My next step is to build the text
executable and run it on a target, to rule out qemu error.
There is an error that catches my attention: A child process outputs
on stderr "/lib/ld-linux-armhf.so.3: No such file or directory\n".
This implies that somehow a fork or execve inside qemu is escaping my
exe_wrapper and running without -L sysroot option, but a strace
revealed a correct qemu execve syscall. Also, if somehow there is an
escape of qemu it is odd it only happens in a specific test. This
failure is reproducible.
There is also a segmentation fault on qemu but I cannot know if it is
qemu or the program. I think the segmentation fault is the test's
fault because just before death there is an assertion fail that does
not happen when i run the test built with my native toolchain.
