You can do lots of compile and link tests, but not any run tests. > Do you count setting up a sys-root ahead of time "manual intervention"? If so, ok. I do. For many cross targets, you start with nothing, so you can't do link tests until after the C library is built, but you can't build the C library until the compiler is built, etc. And many of the tests are "run this" tests; compiling and linking isn't always sufficient. > You have to "cheat" in any case, like starting with a compiler and > linker from somewhere. Um, no. I do cross compilers starting with only a native compiler and the original sources. Note that writing cross development tools is my day job - I do this all the time.
