Hi Andrew, Hi Kei, Our provided glibc uses a mmap2 system call and our linux-kernel uses system calls for 32bit uids. http://www.linux-m32r.org/eng/download.html But the dummy system call routine of m32r-linux-sim have not supported that. This patch fixes these problems. Please commit it. Regards, Kazuhiro Inaoka sim/m32r/ChangeLog 2004-12-06 Kazuhiro Inaoka * traps-linux.c (m32r_trap): Added dymmy systemcall's entries of __NR_mmap2, __NR_lchown32, __NR_getuid32, __NR_getgid32, __NR_geteuid32, __NR_getegid32, __NR_getgroups32, __NR_fchown32, __NR_setfsuid32, __NR_setfsgid32, __NR_getresuid32, __NR_getresgid32 and __NR_chown32. * syscall.h: Added new definitions of system call number.
