I got a link error when compiling 2 loadable kernel modules - "endianness incompatible with that of the selected emulation". But both kernel and the kernel modules of error are in big endian. I don't know what I should check or fix. Any suggestions? I checked the endianess of the kernel by checking the elf header of vmlinux file, is that the right way to do it? Below are the error info and the readelf output, showing both the kernel and a kernel module are in big endian. Thanks for your help.
