I'm in the process of updating the UB docs and that includes text from John explaining the changes in directory layout, including this one that should be out today or tomorrow the reason was the intent to package all binaries for a given flavor under rtlib/<flavorname>, and to wrap those files into a package which can be separately installed or upgraed if you have binaries with pathnames which are in several packages you'd get conflicts when you install several flavor packages as one would overwrite the binary of the other; using per-flavor paths gets around the issue > > On a related issue, I am still having to provide a full hard-coded path > to the PRU binary, so I have the following in the BeBoPr.ini file: > > [PRUCONF] > DRIVER=hal_pru_generic > CONFIG=prucode=/home/linuxcnc/linuxcnc/rtlib/xenomai/pru_generic.bin > pru=1 num_stepgens=4 num_pwmgens=3 > > Is there an easy way to point to files (from within C code) inside the > active linuxcnc run-in-place build? yes, there is; the pertinent paths can be pulled from etc/linuxcnc/rtapi.ini by means of calling get_rtapi_config(): https://github.com/mhaberler/linuxcnc/blob/unified-build-candidate-2/src/rtapi/rtapi_compat.c#L274 see linuxcnc/src$ grep -r get_rtapi_config src for some usage examples - Michael ------------------------------------------------------------------------------ Learn the latest--Visual Studio 2012, SharePoint 2013, SQL 2012, more!
