+A link name was given with an empty name.
+
+Erroneous code example:
+
+```compile_fail,E0454
+#[link(name = "")] extern "C" {}
+// error: `#[link(name = "")]` given with empty name
+```
+
+The rust compiler cannot link to an external library if you don't give it its
+name. Example:
+
+```no_run
+#[link(name = "some_lib")] extern "C" {} // ok!
+```
