@GamePad64 I'm also having this issue on nightly-2023-02-23
. This is because core::ffi::c_char
and u8
are identical on armhf
target.
The c_char
element is defined as this :
mod c_char_definition {
cfg_if! {
// These are the targets on which c_char is unsigned.
if #[cfg(any(
all(
target_os = "linux",
any(
target_arch = "aarch64",
target_arch = "arm",
target_arch = "hexagon",
target_arch = "powerpc",
target_arch = "powerpc64",
target_arch = "s390x",
target_arch = "riscv64",
target_arch = "riscv32"
)
),
all(target_os = "android", any(target_arch = "aarch64", target_arch = "arm")),
all(target_os = "l4re", target_arch = "x86_64"),
all(
any(target_os = "freebsd", target_os = "openbsd"),
any(
target_arch = "aarch64",
target_arch = "arm",
target_arch = "powerpc",
target_arch = "powerpc64",
target_arch = "riscv64"
)
),
all(
target_os = "netbsd",
any(target_arch = "aarch64", target_arch = "arm", target_arch = "powerpc")
),
all(
target_os = "vxworks",
any(
target_arch = "aarch64",
target_arch = "arm",
target_arch = "powerpc64",
target_arch = "powerpc"
)
),
all(target_os = "fuchsia", target_arch = "aarch64"),
target_os = "horizon"
))] {
pub type c_char = u8;
pub type NonZero_c_char = crate::num::NonZeroU8;
} else {
// On every other target, c_char is signed.
pub type c_char = i8;
pub type NonZero_c_char = crate::num::NonZeroI8;
}
}
}
The solution would be to exclude the TryFrom ffi function when c_cach == u8.

What Rust version are you trying to compile against?
from advmac.
And a quick and dirty solution would be to add a "feature" to enable/disable ffi parsing if you don't want to bother with managing all different platforms.
