Hi, I patched the 2.4.20-8 (redhat 9) kernel which is distributed with their CD , with a new system call i made. But its unfortunate I have tried every possible way to recompile the kernel and have 2 kernel one original and second patched one. Problem is as follow: If in "make menuconfig" i enable module versioning then while "make modules" it will give some weird Parse errors , and if i disable the versioning info then everything goes right way and new kernel boots, but inside it if i say depmod -a ,it will give bunch of unresolved symbols showing the /lib/modules/2.4.20-8 directory,while new kernel's module directory is /lib/module/2.4.20-8custom, I verified nearly everything and also made googling. Please try to sort out this thing. Thanks Prasanna __________________________________ Do you Yahoo!? Yahoo!
