I do get the same (I think) fmin error on the reatime build though. make[1]: Leaving directory `/usr/src/linux-headers-2.6.32-122-rtai' /home/samco/linuxcnc-arc-case/src/emc/tp/tc.c: In function ‘tcFindBlendTolerance’: /home/samco/linuxcnc-arc-case/src/emc/tp/tc.c:397: error: implicit declaration of function ‘fmin’ make[2]: *** [/home/samco/linuxcnc-arc-case/src/emc/tp/tc.o] Error 1 make[1]: *** [_module_/home/samco/linuxcnc-arc-case/src] Error 2 make: *** [modules] Error 2 make: Leaving directory `/home/samco/linuxcnc-arc-case/src' samco@samco-desktop:~/linuxcnc-arc-case/src$ git pull Already up-to-date. samco@samco-desktop:~/linuxcnc-arc-case/src$ git describe v2.5.3-2703-g0b74121 samco@samco-desktop:~/linuxcnc-arc-case/src$
