Hi all. This is the error that I am getting when I try to compile a loadable module(it tries to intercept a system call by directly editing the sys_call_table in the memory):- make -C /lib/modules/2.6.32-504.1.3.el6.x86_64/build M= modules make[1]: Entering directory `/usr/src/kernels/2.6.32-504.1.3.el6.x86_64' make[2]: Nothing to be done for `all'. CHK include/linux/version.h CHK include/linux/utsrelease.h SYMLINK include/asm -> include/asm-x86 make[2]: *** No rule to make target `missing-syscalls'. Stop. make[1]: *** [prepare0] Error 2 make[1]: Leaving directory `/usr/src/kernels/2.6.32-504.1.3.el6.x86_64' make: *** [all] Error 2 The Makefile is:- obj-m +:= hijack.o PWD := $(pwd) all: make -C /lib/modules/2.6.32-504.1.3.el6.x86_64/build M=$(PWD) modules clean: make -C /lib/modules/2.6.32-504.1.3.el6.x86_64/build M=$(PWD) clean I have googled the error but most links are unresolved. I am trying to install this against the currently running kernel and not the complete source.
