Error code E0464
The compiler found multiple library files with the requested crate name.
// aux-build:crateresolve-1.rs // aux-build:crateresolve-2.rs // aux-build:crateresolve-3.rs extern crate crateresolve; //~^ ERROR multiple candidates for `rlib` dependency `crateresolve` found fn main() {}
This error can occur in several different cases -- for example, when using
extern crate
or passing --extern
options without crate paths. It can also be
caused by caching issues with the build directory, in which case cargo clean
may help.
In the above example, there are three different library files, all of which define the same crate name. Without providing a full path, there is no way for the compiler to know which crate it should use.
