Seems you are missing to include some necessary header files and/or to provide the necessary compiler options.
I am taking a driver I wrote for a 2.4.2 kernel, built with 2.95.x compiler and trying to port it to 82xx from 8xx and use the new ELDK. Since it is so simple, it just writes to a mem mapped I/O port to set some LED's on/off, I assumed it would be pretty simple. But alas, that was probably a bad assumption on my part. The main module includes the following: linux/module.h linux/fs.h asm/io.h asm/uaccess.h in that order. I have grep'ed for CONFIG_KERNEL_START and CONFIG_TASK_SIZE and the only place I can find them defined is in the kernel source .config (and default config files for each board). Not in any of the header files. Maybe I am sposed to #define them myself - I tried that and it worked - but would like a more automagic solution if there is one! Command line options are: -D__KERNEL__ -DMODULE -Wall -fno-builtins -O -c
It's difficult to guess what exactly is missing given so little information.
