- Both of the results passed the compilation (with warnings).
- And both them failed to compile hello_world program on host computer.
-
- Stupid question:
- Is the cross-compiled gcc supposed to work only on that processor?
- The other alternative is that it would work on host processor, but
- would compile binaries for the other processor.
