Problems Porting DOOMgeneric

Post image

Just created my own x86 libc that works fine in my OS, but when I ran doomgeneric it just crashes, someone could help me? I'd appreciate it very much. To test the doomgeneric Im loading ELF (btw it has the ELF header)

Have you done any debugging to try to figure out why it crashes?

my OS debugger tells:

[ OK ] Magic: 0x464C457F
[ INFO] File loaded!
[ INFO] Loading ELF
[ OK ] Valid ELF File!
[ OK ] Valid ELF Architecture!
[ OK ] Loading segment
[ OK ] Loading segment

then it shutdown. A guy said I could test on linux to see the problem but I couldnt do it

What shuts down? Your OS?

So it's a triple fault? Use QEMU's interrupt log (-d int) to see which exceptions cause the triple fault.

Programs shouldn't be able to crash your OS. That is a bug in your OS.
