i am attempting to build emc-1.0 from the source file found on the bdi-4.51 cd.  i have kernel i am having trouble satisfying the compiler with the MODULE_PARM macro in emcmodule.c.   when i use uname -r it shows  2.6.24-16-rtai if that helps.

The MODULE_PARM macro was finally dropped when the 2.6.17 kernel was released, so running on anything more recent requires changes in that area.

i have hunted around a bit and found some apparent similar macros like RTAI_MODULE_PARM  and "module_parm" but these do not appear direct replacements  and i am not sure how to proceed.  could you point me in the right direction?

You could include rtai_wrappers.h (if it isn't already pulled in indirectly) and changing each occurrence of MODULE_PARM. Rather than doing that, I would favour bypassing any third party macros and switching to module_param. http://lwn.net/images/pdf/LDD3/ch02.pdf page 35-37 covers the format of module_param. Looking at my local repository, I see the relevant changes were made back in June 2006 (and a few bug fixes have been committed since). It may be easier if I sent you a more recent tarball.
