[Scigraphica-devel] Warnings about gtkplot.c

[R. L. <la...@po...>]

When compiling gtkextra, I get the following compiler warning:

gtkplot.c: In function `gtk_plot_calc_ticks':
gtkplot.c:2954: warning: `tick' might be used uninitialized in this function
gtkplot.c:3054: warning: `tick_step' might be used uninitialized in this function

Are you sure 'tick' and 'tick_step' will get the appropriate values in gtk_plot_calc_ticks ?
(Is a plot always either GTK_PLOT_SCALE_LINEAR or GTK_PLOT_SCALE_LOG10 ? ).

You also could define 'gdouble tick' more restrictive (as restrictive as tick_step):

  remove its declaration from line 2954, and add
    line 2023/24: gdouble tick_step = min;
                  gdouble tick = min;
    line 3054: gdouble tick_step;
               gdouble tick;

The compiler will still send out a warning since in 3054 'tick' and 'tick_step' might be uninitialized ?!?
