I don't know about OpenSuse 42.1, but on my machine (Debian Stretch), that symbol (XtAddCallback) is supplied by libXt.so, supplied by the debian package named libxt, version 1.1.5. Do you have that library installed? We had a bug in the build system of some older versions of LinuxCNC where it would place the command-line arguments to the linker in the wrong order, and sometimes fail to find symbols supplied by some of the libraries. Can you try LinuxCNC 2.7 and see if this fixes your problem? -- Sebastian Kuzminsky ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, SlashDot.org! http://sdm.link/slashdot _______________________________________________ Emc-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-users
