Re: cross-compiler intel -> powerpc-gnu-linux

Hi Bob,

I remember this problem and it is very frustrating.  I can't rember how 
I solved it.  I'll have to look through my build scripts when I get 
home.  I have a feeling that I had the "preinstall" the header files 
manually.  ie. copy header files to $prefix/$target/include.  Also make 
sure the linux header files are there too.  I usually just use a 
symbolic link to the kernel headers.  Make sure it is not the kernel 
headers for your host (ie. /usr/include/linux or 
/usr/src/linux/include/linux) as the asm symbolic link will be wrong.
I can't be more specific at this stage but will have a better idea of 
what I did when I look at my build scripts.

BTW: I think the binutils I used was 2.9.5.0.24.  I'm sure there is a 
later version now.  I got it from H.Lu's site at vasystems.  I can't 
remeber the URL at the moment but I'm sure it must be in the archives 
somewhere.  I know that 2.9.1 is outdated and some problems were fixed 
for the powerpc.
