These members are present only when gcc compiles for sparc64. > make[2]: *** [strace-syscall.o] Error 1 > make[2]: Leaving directory `/strace' > make[1]: *** [all-recursive] Error 1 > make[1]: Leaving directory `/strace' > make: *** [all] Error 2 Looks like you are trying to build strace for sparc64 using either 32-bit userspace or gcc that builds for -m32 by default. Try something like CC='gcc -m64'. -- ldv
