// Previously, rustc mandated that cdylibs could only link against rlibs as dependencies,
|
||
|
|
// making linkage between cdylibs and dylibs impossible. After this was changed in #68448,
|
||
|
|
// this test attempts to link both `foo` (a cdylib) and `bar` (a dylib) and checks that
|
||
|
|
// both compilation and execution are successful.
|
||
|
|
// See https://github.com/rust-lang/rust/pull/68448
|
||
|
|
|
||
|
|
//@ ignore-cross-compile
|
||
|
|
// Reason: the compiled binary is executed
