Thanks a lot Mathieu. I tried KERNELDIR, but still seeing the same error,

The sig_ok field of struct module should only be used when CONFIG_MODULE_SIG is defined. This looks like a kernel config mismatch. You might want to ensure you use KERNELDIR=path_to_kernel_source make to build lttng-modules. [root@million lttng-modules-2.4.0]# Patches provided In lttng-modules/linux-patches/ backport-kallsym-sym-2.6.32.patch <-- got easily applied with patch command backport-splice-sym-2.6.32-34.patch <-- got easily applied with patch command backport-tracepoint-data-2.6.32-33.patch <-- Conflicts were found, and I manually edited tracepoint.h file. Kernel was built by disabling “CONFIG_MODULE_SIG”. Hrm, is this a kind of Frankeinstein kernel ? Arguably, the RHEL6-based kernels has a set of features taken from kernels between 2.6.32 and 2.6.35, but even at 2.6.35, the kernel does not appear to implement CONFIG_MODULE_SIG. This makes me wonder why CONFIG_MODULE_SIG appears in the .config file at all. Thanks, Mathieu Could you please kindly guide me on this issue. Appreciate your help very much. Please do let me know, if I need to provide any more info on this.
