Re: [Emc-developers] configure
Hi Andy, I suggest not to bother for now. Sounds like a great entry-level job for the next generation of devs joining to become familiar with it all. :) Best, Steffen > Gesendet: Montag, 24.

Re: [Emc-developers] Linking a new library?

I tried re-writing it all in C, and it didn't help. I think that I might have worked it out, it looks like adding the -lgpiod to the Submakefile for rtapi.app is the way to do it. Now I need to work out the _right_ way to do that. Do I add it only if gpiod is present on the system? Or if the target architecture is ARM? Or what? $(Q)$(CXX) -rdynamic $(LDFLAGS) -o $@ $^ $(LIBDL) -pthread -lrt $(LIBUDEV_LIBS) -ldl -lgpiod It feels like it should be part of LIBDL ? -- atp "A motorcycle is a bicycle with a pandemonium attachment and is designed for the especial use of mechanical geniuses, daredevils and lunatics." — George Fitch, Atlanta Constitution Newspaper, 1912 ___ Emc-developers mailing list Emc-developers@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-developers
