Xaw3d is getting linked in. xlwgauge for instance is including stuff like... #include <X11/Xaw/XawInit.h> #include <X11/Xaw/LabelP.h> and then using #ifdef _ThreeDP_h i.e. it assusmes Xaw3d was installed to overwrite the normal headers.. However in my case X11/Xaw is the normal Xaw and the Xaw3d headers are in Xaw3d/ (note the missing X11). So probably xlwgauge (and the other xaw widgets) should be changed to do either #ifdef HAVE_XAW3D # include <Xaw3D/LabelP.h> #else # include <X11/Xaw/LabelP.h> #endif or to just #include "LabelP.h" and then the Makefile should be changed to include the right dir with -I if it is not already doing so.
