1 year ago I don't see a lot of information here about what the actual error is -- I'd probably start out by looking at the exact contents of ffitarget.h (this all comes from libffi itself, so this is not a Meson bug).
That being said, your cross file is probably broken. It specifies target_machine but not host_machine. Per https://mesonbuild.com/Cross-compilation.html that means you're trying to run Meson on an unidentified CPU/OS called "X" and produce native binaries that run on "X", but those binaries are a cross compiler or other software that then emits cross code generation for arm cortex.
Gstreamer is not a compiler, so you should not need to care about target_machine.
When I do a native meson build of gstreamer, there are no problems. When I try to cross-compile for ARM, I get a fatal error:
gstreamer/build-cross-arm/subprojects/libffi/src/../include/ffitarget.h:12:10: fatal error: ffitarget-arm.h: No such file or directory #include "ffitarget-arm.h"
I am raising this issue here rather than in gstreamer first as I suspect it is an issue with meson (or indeed me) passing the correct parameters to the subproject libffi of gstreamer. Here is the meson command line that I am using:
meson build-cross-arm --cross-file=../cross-files/arm-cortex_a8-linux-gnueabihf-meson-cross-file.txt
and the associated cross-compile configuration file: [target_machine] system = 'linux' cpu_family = 'arm' cpu = 'cortex-a7' endian = 'little'
