undefined references to `__stack_chk_fail' during pintos installation

Question

I am trying to install pintos in Ubuntu 13.10 but while doing the 'make' command in the thread folder, I got the error

"more undefined references to `__stack_chk_fail' follow make[1]: * [kernel.o] Error 1 "

As iam encountering this error for the first time, I can't figure out this.

Answer 1

Ubuntu's GCC by default enables the -fstack-protector flag, which defends against stack overflow attacks (more info on their wiki). You'll have to add -fno-stack-protector to the compiler flags.
