Hello Everyone, I wrote a simple kernel module such as helloworld. After compiled to hello.ko, I got the error message as "init_module 'hello.ko' failed (Exec format error)" when I performed command as "insmod hello.ko". The debug message is "<4>hello: disagrees about version of symbol module_layout". Does someone help me to fix it ?? Thank you so much!! ============================================================================ root@android: # insmod hello.ko insmod: init_module 'hello.ko' failed (Exec format error) root@android: # dmesg <4>hello: disagrees about version of symbol module_layout ... ============================================================================
