Such a parameter is no more configurable with RTAI-5.0. I was calling rtai's configure script with "--enable-lxrt-use-linux-syscall", a carry-over from how I called it back in the 3.9 days. configure did not complain, and the build worked fine. I see that CONFIG_RTAI_LXRT_USE_LINUX_SYSCALL is still mentioned in many places in the code and in the configure script, but it's not in the Kconfig any more. I removed that argument from the configure line, and now when I load rtai I no longer see the "uses LINUX SYSCALLS" in dmesg, but I still have the problem that I originally reported (or maybe a similar one): http://highlab.com/~seb/rtai/amd64-problem.2015-12-13/kernel-problems -- Sebastian Kuzminsky _______________________________________________ Rtai mailing list [email protected] https://mail.rtai.org/cgi-bin/mailman/listinfo/rtai
