nanogui: Thread: Porting nano-X to uClinux on M68VZ328

Needing additional direction...
 
I have successfully downloaded microwindows and nano-X to my desktop and
rebuilt the libraries.  I then wrote an example application for
displaying bitmap images and rectangles, etc.
 
Now I want to port this example application to an embedded system that
is running uClinux on a Motorola M68VZ328 DragonBall processor.  My
display is an LCD that is 160x240 pixels and it will run in a black and
white mode only.
 
Any way, I am very confused about how to configure the microwindows and
nano-X libraries to understand this different hardware.  There has to be
more to it than just redefining the display width and height in the
config file and enabling framebuffer support.  Do drivers all ready
exist for various hardware platforms?  Seems this hardware layer is not
really discussed in sufficient detail anywhere.
 
Newbie needing some more guidance.
 
Thanks

if your display hardware is a framebuffer, that's almost all there is to
it.

take a look in src/drivers at the various scr_*.c files .  that should
give you an idea how things are structured, and some of the drivers
available.

Microwindows has been primarily used on Linux systems, 
where it takes advantage of the kernel-based framebuffer
driver, available for most hardware platforms.  This provides
a server-program accessible memory area that when written
to, dots appear on the display.

For ucLinux, you will likely have to write your own kernel
framebuffer driver.  If there is such a thing and it uses
the standard Linux framebuffer interface, then the standard
Microwindows screen driver (drivers/scr_fb.c) will work.
Otherwise, you'll need to write in addition a Microwindows
screen driver for the particular kernel framebuffer implementation.

For more details on the screen driver, see the Architecture 
document on the mwin web site.

Hi, all:

  Now I want to port some example application to an embedded system that is running uClinux on a Motorola M68VZ328 DragonBall processor.  My display is an LCD that is 320x240 pixels and it will run in a black and  white mode only.

  But I failed to compile micrwin on uClinux, can anyone help me? 

  The distribution I use is uClinux-dist-20040408.tar.gz，and the version of the m68k tools is m68k-elf-tools-20031003.sh.

  Bellow is the err file when I run 'make user_only 2> errs_user':

Hi,

 

I have the same problem when trying to add Microwin into the compilation for
uClinux 2-4-x. I have the following errors:

 

cc1: Invalid option '6800'

cc1: Invalid option 'id-shared-library-id=0'

 

Can anyone help?

 

 

 

: I have the same problem when trying to add Microwin into the compilation

: uClinux 2-4-x. I have the following errors:
: cc1: Invalid option '6800'
: cc1: Invalid option 'id-shared-library-id=0'

It appears that ucLinux has an old version of Microwindows and
compiler makefiles included, which need to be changed.  I suggest
pulling down 0.90 or CVS and using that version directly.

Regards,

Greg
