Hi, I want to test L4linux on top of L4/fisco I follow the building page of Fiasco, for this one all be done without error. So I start to follow the instructions to build L4re. I use the default configuration file. The results of the command "make O=path/to/builddir" failed because of an undefined reference to _stack_chk_fail_local. After some research I understand this "undefined reference" is add by gcc which is in version 4.4.4 on my fedora 13 OS. One soultion is to add CFLAGS= -fno-stack-protector in gcc command but I don't find gcc command in Makefile...! Do you have a solution ? Thanks in advance. -- ------------------------------------------------ Maxime LASTERA Phd Student Dependable Computing and Fault Tolerance group LAAS-CNRS 7 av Colonel Roche 31077 Toulouse E-mail: mlastera@laas.fr Phone : +33561336979 ------------------------------------------------
