reference to packed field is unaligned

[CheetoTrump]

Ive tried ntapi = "0.4.1" ntapi = "0.4.0" ntapi = "0.3.7"

and 32bit and 64bit for each version

I get these errors when compiling the crate

This was fixed in the 0.4 release. From the paths in the logs above, you're still using ntapi-0.3.7

I don't quite get it, why is Cargo/the compiler still using version 0.3.7 of the lib even if one has set explicitly ntapi = "0.4" in Cargo.toml

[eminence]

You probably have some other dependency that is requiring 0.3.7 (so both 0.3.7 and 0.4.x are brought into your crate graph).

Try running cargo tree -i ntapi to see all the packages that depend on ntapi

i should have sent all 3 errors but i didnt, they were 1:1 but different versions of ntapi

cargo update may help in such cases
