The Linux paths in env.sh are incorrect. Fix: update them to match the directory names produced when unzipping gcc and qemu.
The source file name app.S does not match app.s in the Makefile. This causes failures on case-sensitive file systems. Our test environment did not expose this issue. Fix: rename app.S to app.s; future labs will consistently use app.s.
For Lab1, a free two-day extension is available if requested before the deadline. You need to send the request to the staff mailing list at cs6640-staff@ccs.neu.edu.
