[ECOS] compiling safl.c

[ECOS] compiling safl.c

[Jesus Molina]

Hello,

I am working with a strongARM ebsa285 board. kernel version
2.4.0-test10.
I have problems compiling the flash drivers. These are the
problems.

Trying to compile safl.c the pointed modversions.h was a "fake" saying
#error Modules should never use kernel-headers system headers
#error but headers from an appropriate kernel-source file.
I chanded the -f option of teh Makefile to a copy of modversions.h in the
sources.

Also when compiling vm_offset was not found. It seems that in 2.4.0, The
vm_offset member of the vm_area_struct definition (<linux/mm.h>) seems to
have been replaced with vm_pgoff. I replaced this, and finally i get my .o
driver, but with a lot of warnings. and an unresolved symbol safl-scan, so
I cannot install the module. When compiling, the exact error is:

In function 'init-module':
safl.c:200: warning: impllicit declaration of function 'safl_scan'

Anybody knows why this symbol is unresolved?

Regards,
Jesus

Yes, this module has not been updated for kernel 2.4.0 :-). Try
conditionalizing the init_module function in salf.c to only be present for
2.3 and up, i.e.

#ifdef LINUX_VERSION_CODE < 0x23000
int
init_module(void)
{
    if (safl_debug)
        printk(KERN_INFO "%s", version);
    return safl_scan();
}
#else
module_init( safl_scan() )
#endif

If you do get it working, please try and send us all the changes you made!
