ok - riddle me this (as in - what am I doing wrong) I did this git clone git://git.linuxcnc.org/git/linuxcnc.git linuxcnc-circ cd linuxcnc-circ git remote add github-robE https://github.com/robEllenberg/linuxcnc-mirror.git git fetch github-robE git checkout -b 3d-blend-arc-techdemo github-robE/feature/3d-blend-arc-techdemo cd src ./autogen.sh ./configure --enable-run-in-place (had to install sudo apt-get install libmodbus-dev) make I get these errors /home/samco/linuxcnc-circ/src/emc/kinematics/tp.c: In function tpInitializeNewSegment: /home/samco/linuxcnc-circ/src/emc/kinematics/tp.c:369: error: implicit declaration of function fmin /home/samco/linuxcnc-circ/src/emc/kinematics/tp.c: In function tpCreateBlendArc: /home/samco/linuxcnc-circ/src/emc/kinematics/tp.c:529: error: implicit declaration of function fmax make[2]: *** [/home/samco/linuxcnc-circ/src/emc/kinematics/tp.o] Error 1 make[1]: *** [_module_/home/samco/linuxcnc-circ/src] Error 2 make: *** [modules] Error 2 make: Leaving directory `/home/samco/linuxcnc-circ/src'
