This is not strange, see the values of E* macros ENOSYS = 0x4000004e, /* Function not implemented */ So that's it. Getting ENOSYS is odd, though, since open64 is defined in glibc/sysdeps/mach/hurd/open.c It's probably useful to debug step by step to see what function is actually getting called. Samuel
