I have a LTT 0.95 patched 2.4.19 kernel and also compiled RTAI 3.0 with LTT support but when I load rtai_lxrt.o I get unresolved symbols trace_true_lxrt_rtai_syscall_[entry, exit]. Previously loaded modules are rtai_[trace, hal].o in that order. The LTT tracer is compiled into the kernel and works fine. Anyone who knows why I get unresolved symbols? regards, /c
