Hi all, I am trying to write a kernel module that shares some data with a userland process using shared memory. The kernel module compiles with some warnings: WARNING: "sys_shmat" [/home/lnookx/shared_memory_tests/module/shmem_server_module.ko] undefined! WARNING: "sys_shmget" [/home/lnookx/shared_memory_tests/module/shmem_server_module.ko] undefined! and when I try to load the kernel module I get: insmod: error inserting './shmem_server_module.ko': -1 Unknown symbol in module and in dmesg I see: shmem_server_module: Unknown symbol sys_shmat shmem_server_module: Unknown symbol sys_shmget Has anyone else seen these errors, and knows how to correct them?
