Hi Iam trying to implement a new system call ("test") in linux kernel. when iam done with make dep and do make bzImage, i get the following error: In arch/i386/kernel/kernel.o: In function 'sys_call_table': arch/i386/kernel/kernel.o(data+0x3d4): undefined reference to 'sys_test' I am using kernel 2.4.2. and the last few lines of my my /arch/i386/kernel/entry.S looks like this: .rept NR_syscalls-(.-sys_call_table)/4 .long SYMBOL_NAME (sys_ni_syscall) .endr and there are 226 system call entries in /arch/i386/kernel/entry.S and in /include/asm/unistd.h . This number includes even my system call entry. can someone help me in resolving this error?? Thanks! Charu.
