Hi all, long time no see! i'm trying to build EMCapplication for an arm64 platform (Xilinx Zynq Ultrascale), alas things are changed quite a bit from last time i managed to make it work on a Zynq7000 some years ago! i think i managed to have machinekit-hal up and running, tests are a go, and i can halrun some examples with halscope and basic functionalities.
Trying setting up EMCapplication following this receipe: https://github.com/machinekit/EMCApplication/issues/1#issue-666660311 seems to complete without complains, but when i run linuxcnc i get this: *LINUXCNC - 2.9.0~pre0* *Machine configuration directory is '/home/zus/linuxcnc/configs/sim.axis'* *Machine configuration file is 'axis_mm.ini'* *Starting LinuxCNC...* *rtapi_msgd command: /usr/libexec/machinekit/rtapi_msgd --instance=0 --rtmsglevel=1 --usrmsglevel=1 --debug=1 --halsize=524288* *rtapi_app command: /usr/libexec/machinekit/rtapi_app --instance=0 --debug=1* *Found file(lib): /usr/share/linuxcnc/hallib/core_sim.hal* *Found file(lib): /usr/share/linuxcnc/hallib/sim_spindle_encoder.hal* *Found file(lib): /usr/share/linuxcnc/hallib/axis_manualtoolchange.hal* *Traceback (most recent call last):* * File "/usr/bin/hal_manualtoolchange", line 11, in <module>* * import linuxcnc, hal* * File "/home/zus/machinekit-hal/lib/python/hal.py", line 30, in <module>* * import _hal* *ImportError: /home/zus/machinekit-hal/lib/python/_hal.so: undefined symbol: _Py_FalseStruct* */usr/share/linuxcnc/hallib/axis_manualtoolchange.hal:1: hal_manualtoolchange exited without becoming ready* *Shutting down and cleaning up LinuxCNC...* *LinuxCNC terminated with an error.
