When compiling on Suse11: linux-user/syscall.o: In function `do_syscall': /work/linux-user/syscall.c:8090: undefined reference to `syncfs' library support was added to glibc in version 2.14, which newer than the glibc in the oldest distros qemu building is still supported (2.11 in Sles11). CONFIG_SYNCFS checki and guard needed. Riku > case TARGET_NR_kill: > ret = get_errno(safe_kill(arg1, target_to_host_signal(arg2))); > break; > -- > 2.9.3 >
