[gps-devel] GPS with Mac Leopard Adventures

[Roger Mc Murtrie]

Hello Nicolas,
"all this trouble" is probably due to this being my first time to try  
and build GPS.
No doubt, having successfully built it once, future upgrading  
shouldn't be a problem (I hope).
In retrospect, I should have got GtkAda working correctly first as it  
was the Get_Pixel_Size problem that caused most of my problems.
 From backtraces, I suspect the Get_Pixel_Size problem may have  
something to do with pango which I know nothing about.
According to Fink, I am using gtk+2 version 2.12.1-1
 From config.log:
GTK_LIBS='-L/usr/local/lib/gtkada -lgtkada -L/usr/local/lib -L/usr/X11/ 
lib -L/sw/lib -lgtk-x11-2.0 -lgdk-x11-2.0 -latk-1.0 -lgdk_pixbuf-2.0 - 
lm -lpangocairo-1.0 -lfontconfig -lXext -lXrender -lXinerama -lXrandr - 
lXcursor -lXcomposite -lXdamage -lpango-1.0 -lcairo -lX11 -lXfixes - 
lgobject-2.0 -lgmodule-2.0 -lglib-2.0 -lintl -liconv'
GTK_PREFIX='/sw'
GTK_STATIC_LIBS='/usr/local/lib/gtkada/libgtkada.a -L/usr/local/lib -L/ 
usr/X11/lib -L/sw/lib -lgtk-x11-2.0 -lgdk-x11-2.0 -latk-1.0 - 
lgdk_pixbuf-2.0 -lm -lpangocairo-1.0 -lfontconfig -lXext -lXrender - 
lXinerama -lXrandr -lXcursor -lXcomposite -lXdamage -lpango-1.0 - 
lcairo -lX11 -lXfixes -lgobject-2.0 -lgmodule-2.0 -lglib-2.0 -lintl - 
liconv'

How do I find out and set X11 color depth?

My remaining (?) problem is most easily instigated by trying to resize  
the main gps window:

  :~/Desktop/Ada/gps-4.0.2 Roger$gps/obj/gps
The program 'gps' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadMatch (invalid parameter attributes)'.
   (Details: serial 3918 error_code 8 request_code 70 minor_code 0)
   (Note to programmers: normally, X errors are reported asynchronously;
    that is, you will receive the error a while after causing it.
    To debug your program, run it with the --sync command line
    option to change this behavior. You can then get a meaningful
    backtrace from your debugger if you break on the gdk_x_error()  
function.)

Any ideas?

Regards,
Roger
