To Phil and Peter: I confirm this issue on Linux if I use the combination of cmake options -DPL_DEPRECATED=ON -DHAVE_SHAPELIB=OFF. As expected, this build issue does go away if the appendresult declaration and initialization is moved to where it will be compiled in general. However, that is not all the story, because if you also compile example 19 for that case and any device driver (I chose cairo), then there is a long series of warnings issued for that example when you run it, e.g., with examples/c/x19c -dev xcairo Those warning messages start with *** PLPLOT WARNING *** Could not find ss/ss64ne_Landform_Area.map file. That makes no sense. If -DHAVE_SHAPELIB=OFF why in the world should this example (or more likely the core library) be looking for shapelib files? I also tested the case where -DPL_DEPRECATED=OFF -DHAVE_SHAPELIB=OFF, and the code does the right thing there which is emit the following warning *** PLPLOT WARNING *** Use of the old plplot map file format is deprecated. It is recommended that the shapelib library be used to provide map support. @Phil: As original author of this code, would you please fix the -DPL_DEPRECATED=ON -DHAVE_SHAPELIB=OFF case so that the first pages of example 19 come out right (like they do now) using the deprecated way of doing things, but the last page should simply emit the same message as for the -DPL_DEPRECATED=OFF -DHAVE_SHAPELIB=OFF case, i.e., the last WARNING message above?
