+Couldn't find crate `..` with expected target triple `..`.
+
+Example of erroneous code:
+
+`a.rs`
+```ignore (cannot-link-with-other-tests)
+#![crate_type = "lib"]
+
+fn foo() {}
+```
+
+`main.rs`
+```ignore (cannot-link-with-other-tests)
+extern crate a;
+
+fn main() {
+    a::foo();
+}
+```
+
+`a.rs` is then compiled with `--target powerpc-unknown-linux-gnu` and `b.rs`
+with `--target x86_64-unknown-linux-gnu`. `a.rs` is compiled into a binary
+format incompatible with `b.rs`; PowerPC and x86 are totally different
+architectures. This issue also extends to any difference in target triples, as
+`std` is operating-system specific.
+
+This error can be fixed by:
+ * Using [Cargo](../cargo/index.html), the Rust package manager, automatically
+   fixing this issue.
+ * Recompiling either crate so that they target a consistent target triple.
