I was trying to compile shred (from fileutils-4.1) on an machine with an older compiler, which failed because the "rdtsc" intel instruction is only available on Pentium class processors (quote from Nasm documentation): A.141 RDTSC: Read Time-Stamp Counter RDTSC ; 0F 31 [PENT] RDTSC reads the processor's time-stamp counter into EDX:EAX. This in struction is used on line 836. As far as I know, there is no similar instruction on the 386 or 486; the only solution I can think of is to use the generic (C) version on these machines. So the patch should be: sed s/__i386__/__i686__/g Thanks for all the good work, Sean Young _______________________________________________ Bug-fileutils mailing list [EMAIL PROTECTED] http://mail.gnu.org/mailman/listinfo/bug-fileutils
