Khem, Since you seem to use ARM, may i ask you to take a look and clean-up syscalls.h? Specifically this one spot: The INTERNAL_SYSCALL macro is duplicated, apparently needlessly. Search for "r7, v3" in libc/sysdeps/linux/arm/bits/syscalls.h TIA > > OK ? Is this a recent breakage since Pauls thumb patch was applied or was it already there before this patch was applied (about two days ago, or the like)? _______________________________________________ uClibc mailing list uClibc@uclibc.org http://busybox.net/cgi-bin/mailman/listinfo/uclibc
