nanogui: Thread: uClinux/Microwindows Compilation problems - Urgent... help..

Hi,

I have been working on porting Microwindows to uClinux. I am using 68k
architecture. The hardware is Motorola 68EZ328
dragonball.

I successfully built the uClinux kernel 2.0.38. I followed the
instructions from the home page (uclinux.org). I used the m68k-coff
tools for the kernel and m68k-pic-coff for the userland programs. When I
installed from the CD, I was able to build the kernel
well and run it on a terminal window.

Next I was looking at an appropriate GUI for the kernel. Since
microwindows was the most widely used embedded gui currently,
I tried using it. Microwindows currently does not have support for m68k
architecture with nommu. So I basically followed the
instructions on the web page and tried building it using the
m68k-pic-coff tools. Most of the programs do build fine. However,
some programs that are large complain of 'word overflow' errors. And
others that do compile fail during link due to 'relocation or
a5world full' problems. I am attaching herewith the errors I get during
compilation.

I tried my level best with the following alternatives:
1) Changed the compiler to the current m68k-pic-coff (available on the
website)
2) Patched the compiler to the 32 bit version (Erwin's patch) and used
-fPIC option.
3) Used the new crt0.o file (32 bit).
4) Removed the large programs and tried small demo programs.
5) Tried linker options including: --embedded-relocs, -Tdata=0x0
....etc.
6) Modified the memory map uClinux-pic.ld.

But nothing seems to work. I always get the problem of 'a5world full' or
'.text truncation' or '.word overflow'

I have almost given up on this.  Please do help me. Quite
frustrating.....

Also do suggest if there is an alternative GUI that I could try. Or what
if I use a different tool chain like the m68k-elf-.

Thanks,
Sri.

Errors that I get:

1) Linker errors on normal size programs:

You probably need to push more data out of the data segment, paticularly
compiled in images. Changing the code to malloc and load the images and 
using a pointer to them should solve that

That means set FBVGA=N in microwin/src/config

Regards,

sir,
	
	do u know how to fix the problem? that is, do u know how to modify
the Arch.rules now? would u please send me a copy of Arch.rules?

	thanks in advance
