cross compiler needs_exe_wrapper is ignored #5818

Open facorreia opened 5 years ago

facorreia commented 5 years ago

I am using meson version 0.51.1 trying to cross-compiling glib version 2.61.2 in a linux Ubuntu 16.04.4 LTS environment to a linux arm x86_64 but it fail with the error message bellow:

meson.build:1:0: ERROR: Could not invoke sanity test executable: [Errno 8] Exec format error.

it should not to run the sanity executable because needs_exe_wrapper is true in cross config file post bellow for your reference:

Your host machine is incorrect. It specifies an x86_64 machine when it should define an ARM machine. In Meson "host machine" is the machine the output will run on. The machine you are using for compilation is the "build machine".

facorreia commented 5 years ago

ok, you are right. I changed the host_machine properties as you recommended as you can see below. However, It is still failing. I have a question too. Should "needs_exe_wrapper" properties set to true to force meson to not exec test executable? if yes, the value of host_machine properties should not matter, right?

[host_machine] system = 'linux' cpu_family = 'arm' cpu = 'arm32' endian = 'little'

we hit this issue, too.

Any updates? I am hitting this as well. Is there a working version?
