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?
Alan
