Unable to build throwing `FileDescriptor has no member named get’

While trying to crosscompile libcamera-rs (56e2442986bdc4d9be89193bb72254ae8cf969ff) for armv7-unknown-linux-gnueabihf (raspberry) I get:

So apparently there are some outdated API references on this project using libcamera v0.1.0? I've installed dependencies much like shown in the CI:

git clone https://git.libcamera.org/libcamera/libcamera.git --branch v0.1.0
meson setup build
ninja -C build install

Could it be that you have an older version of libcamera, installed by the package manager?

If you look at v0.1.0 code, the missing fields are there: https://github.com/kbingham/libcamera/blob/v0.1.0/include/libcamera/framebuffer.h#L57
