[ARMedslack] ARMED kernel compile errors

Thu Dec 3 16:55:59 UTC 2009

Dear Stuart!

Today i made a kernel configuration that suits my acer pda i mentioned a 
week before, and then i tried to build it in the ARMedslack i installed 
under qemu. I used the 2.6.30.5 kernel source .tgz you supplied with the 
ARMedslack 12.2 distribution. The compilation was stopped with error. 
The problematic file was vgacon.c. Since the vga text console is 
necessary for me, i could not take it out from the kernel options. How 
did you succeed to compile this kernel? What do you think i should do 
with that? This was the gcc error message:
