// rustc will remove one of the two redundant references to foo below. Depending
|
|
// on which one gets removed, we'll get a linker error on SOME platforms (like
|
|
// Linux). On these platforms, when a library is referenced, the linker will
|
|
// only pull in the symbols needed _at that point in time_. If a later library
|
|
// depends on additional symbols from the library, they will not have been pulled
|
|
// in, and you'll get undefined symbols errors.
|
|
//
|
|
// So in this example, we need to ensure that rustc keeps the _later_ reference
|
|
// to foo, and not the former one.
|
|
|
|
//@ ignore-cross-compile
|
|
// Reason: the compiled binary is executed
|
|
//@ ignore-windows-msvc
|
|
// Reason: this test links libraries via link.exe, which only accepts the import library
|
|
// for the dynamic library, i.e. `foo.dll.lib`. However, build_native_dynamic_lib only
|
|
// produces `foo.dll` - the dynamic library itself. To make this test work on MSVC, one
|
|
// would need to derive the import library from the dynamic library.
