2010/11/7 Christian Spoo | WerbeCafé <c.spoo@werbecafe.de>: > However, the compilation failed with an error message referring to undefined references to the BSD syscalls jail_get, jail_set and jail_remove which I was unable to resolve. These syscalls are provided but the glibc stubs are missing. Could you file a bug on libc0.1? In the meantime you can use e.g. syscall(SYS_jail_get, ...) and such. -- Robert Millan
