nanogui: Thread: NOFONTSORCLIPPING = Y

Hi all,
NOFONTSORCLIPPING = Y should cause drivers/nofonts.c to be included 
instead of drivers/genfont.c
But this does not compile as symbols is not linked properly. Can we 
confirm this, and suggest some fixes if required ?

Kindly have a look at my out.log (pasting below).
If you need the config file pls let me konw. I am using NOKEYBOARD, and 
NOMOUSE, have made my own fb_null alongwith.
Regards,
Manav

Hi Manav -
    Its seems that the new make contribution in 0.91 and CVS broke
the NOFONTSORCLIPPING option, which I think was added
for the Sun Java support that only needed GdXXX routines without
fonts.  The 0.90 version still works.

To fix this in 0.91 or CVS, you'll need to modify src/Makefile.rules,
since the $(wildcard ) function is used to load all .o files, rather
than replace genfont.o with nofont.o in this case.

What are you trying to link the Gd routines with, that requires this option?

Regards,

Greg

Hi Greg,
    Thanks for the confirmation! How can I contribute to the CVS? I 
would like to change the Makefile.
    I am working on a ThinClient Project in my company. We're using the 
Microwindows 0.91 version. We ported it to uClinux Blackfin 53x a few 
months back. Though we do not have the complete display hardware we were 
supposed to profile it over our Blackfin Evaluation board and see its 
performance over the network. Hence we've been modifying the src code to 
work without the framebuffer! :-)

Regards,
Manav

Send me the patch in "diff -urN" format, I'll apply it.

I had a doubt before rectifying this. Aren't we supposed to have plug-in 
architecture of the code before we are able attach the nofonts.c to the 
binary?
By plug-in architecture I mean having a pointer to the fonts device 
which inturn contains pointers to the respective function implementations?
The idea is similar to how we've attached different mouse, keyboard, and 
screen drivers to the engine.

Also does the microwindows CVS have a web interface so that I could just 
download selected files from it?

In order not to have to put #ifdefs all over the place, the nofonts.c
just inserts a NULL table for the internal fonts.  Since nano-X
is compiled in this case for no fonts, we assume that font calls
won't be made, and the GrXXX layer won't need to be included.
This was originally for a java implementation, I think where the
font code was handled at their upper level.

We don't really have the notion of a "fonts device".  There's
only an internal table, and then the GdCreateFont routine tries
calling other linked-in font handlers (of which there should be
none specificed in the config file) for all non-internal fonts.

Unfortunately, not at this time.  I really need a volunteer to update
the web site, its way old, uses little technology.  Its seems I much
prefer C to HTML...
