Compilation Error

Compilation Error

[Jeff Stevens]

I am trying to cross compile one of our drivers at
work to run on both an AMCC 440SP platform (Luan2),
and an MPC8540 platform (MPC8540ADS).  I am using the
ELDK compilers (ppc_4xx-gcc and ppc_85xx-gcc), and the
kernel.org 2.6.13 source.  I was getting warnings
about implicit declarations for both dma_cache_wback
and dma_cache_inv.  I went ahead and replaced them
with clean_dcache_range and invalidate_dcache_range
(since that is what they are #defined to), and
included cache.h.  So then I was able to get through
the compilation without the implicit declaration
warnings, but now when it does MODPOST, I get warnings
about clean_dcache_range and invalidate_dcache_range
being undefined!  This driver was originally written
for x86 platforms where dma_cache_wback and
dma_cache_inv both are #defined to inline funtions
within io.h.  Has anyone else seen this?  I'm sure
it's most likely an include issue, but I'm not sure
what else to include.  I have tried dma-mapping.h and
cache.h?  Any help would be greatly appreciated. 
Also, if this is the wrong place for this post, what
is the correct place for this question?

Thanks,
   Jeff Stevens

Hi all,

          I am building  linux-2.4.32 kernel using ELDK tool  for
MPC8248(MPC8272 family) based target board. After configuring kernel as
follow:

   1)Make xconfig ARCH=ppc

 

    Platform support:MPC8260 CPM support -y

                             MPC8272 family Support -y

 

Machine type : ADS8272

 

 

And after saving configuration ..

 

2)Make dep ARCH=ppc

3)Make bzImage ARCH=ppc

         Now  I am getting error like this..............

Hi David,

   I ams til trying to make Ethernet work :-(
 Last time i compiled the kernel without including
some files but now included everything in Bestcomm
directory.

I am getting the following error which I could figure
out what? could you help me ...

As you know mgt_io is nothing but 5xxx_io for you and
the rest is same. It complains while it is linking
everything. I dint find anything like
"askSetup_TASK_FEC_RX" used in
mgt_sdma_fec_rx_task_setup() -->
arch/ppc/mgt_io/sdma.c.

What could be wrong here????
