Cross compile suing meson for arm Arch64

[semrade]

Hello
I want to cross-compile the Aravis librairy for the ARM architecture running on Linux.
The Aravis library use meson, you can find the repo link:https://github.com/AravisProject/aravis
I read the cross-compilation documentation to create the cross-compilation file,

[binaries]
c = '/opt/x86_64-aarch64-none-linux-gnu-8/gcc_arm_8_2_2018_08-x86_64_aarch64_linux_gnu/bin/aarch64-linux-gnu-gcc'
cpp = '/opt/x86_64-aarch64-none-linux-gnu-8/gcc_arm_8_2_2018_08-x86_64_aarch64_linux_gnu/bin/aarch64-linux-gnu-g++'
ar = '/opt/x86_64-aarch64-none-linux-gnu-8/gcc_arm_8_2_2018_08-x86_64_aarch64_linux_gnu/bin/aarch64-linux-gnu-gcc-ar'
strip = '/opt/x86_64-aarch64-none-linux-gnu-8/gcc_arm_8_2_2018_08-x86_64_aarch64_linux_gnu/bin/aarch64-linux-gnu-strip'
pkgconfig = '/usr/bin/aarch64-linux-gnu-pkg-config'
cmake='/usr/bin/cmake'

[properties]
#lib = '/usr/share/glib-2.0'
#c_stdlib = ['lib'] # Subproject name, variable name
c_stdlib = '/usr/share/glib-2.0'

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

meson throws this error message but since I have never used the meson file am asking for help:

Looking for a fallback subproject for the dependency c_stdlib because:
Use of fallback dependencies is forced.

Your cpu_family should be aarch64, arm means 32bit arm, jfyi

[semrade]

Thank you I change it but still has this error
Run-time dependency glib-2.0 found: NO (tried pkgconfig and cmake)

meson.build:59:0: ERROR: Dependency "glib-2.0" not found, tried pkgconfig and cmake

[eli-schwartz]

You should probably just skip the c_stdlib property, that's only really useful for example for embedded development, not normal cross compiling. You want to use the standard library provided with the cross compiler, which simply works out of the box.

[semrade]

Yes thank you for your help,
when I started the complication I didn't add the c_stdlib, I add it because I have an error so I thought maybe there is something missing:
meson.build:59:0: ERROR: Dependency "glib-2.0" not found, tried pkgconfig and cmake

[eli-schwartz]

Aha! That means that a third-party library dependency (not the C standard library) was not found. You'll need to either define pkg_config_path to the location where GLib (the gnome library, not the GNU standard C library) is installed, or run meson wrap install glib to import a vendored copy that will be built private to this project when a dependency isn't found.

[semrade]

OK, I prefer the meson wrap install glib version, do I run this command before the meson meson setup --cross-file xxx.txt build-dir is executed or after? I'm sorry I'm not familiar with meson and I don't really know about this compilation method.
could you explain more about the first point, please? third-party library dependency
Thank you :)

[semrade]

after runing the meson wrip install glib this is the output

the log is very long and I don't know if it is convenient to share her ...
