Hi. I'm trying to build a (add-on) module on a machine booted from a 2.6-test4 kernel, And keep running into this error. I've included a sample program , and gcc command line. I built the kernel: make defconfig; It is a 2W SMP (Compaq ML850) couple minor modes like enet & SCSI device make My general question is, should I include the -I/work/src//include/asm-i386/mach-generic/mach_mpspec.h in my gcc command line or is my build area incorrect is some way that the correct mpspec.h file can't be found ? Thx. JD. __________________________________ Do you Yahoo!? Yahoo! SiteBuilder - Free, easy-to-use web site design software http://sitebuilder.yahoo.com
