Re: [microblaze-uclinux] Kernel/Dist source checkout -and- kernelbuild under new toolset
Hi Jim,
It is my understanding that the current CVS head (both uClinux-dist and
uClinux-2.4.x) kernel build cleanly for the ml401 and uclinux-auto
platform, with the latest gcc-3.4 toolchain, without any patches required.
If anybody has experienced otherwise, I'd really like to hear about it.
It is curious as to why you would have problems with the newer tools,
but not the older ones.
Just to be sure, you should do a full make clean (or even, "make
distclean") when you toggle compiler versions, and also delete the files
mentioned in my earlier post:
"delete the files linux-2.4.x/arch/microblaze/kernel/microblaze_defs.d
and .h, the first time you build with the new compiler."
To David Banas - have you had a chance to test your patches with the new
tools and latest CVS? If you can generate some clean and known-good
patches we can get them committed into the SnapGear tree.
Regards,
John
