Hi thanks for the info, I will try and download the source code from the codesourcery website so I can see which version of gcc / bin / libc they are using and then use your instructions in the text file to hopefully build a new toolchain.
I think its important to update the ARM toolchain as ARM are moving to the newer cortex devices, and I for one would like to see uClinux up and running on these new devices. I will email my progress. regards steve --- On Tue, 11/24/09, Greg Ungerer <g...@snapgear.com> wrote: > From: Greg Ungerer <g...@snapgear.com> > Subject: Re: [uClinux-dev] ARM support > To: "uClinux development list" <uclinux-dev@uclinux.org> > Date: Tuesday, November 24, 2009, 7:22 AM > > Hi Steven, > > steven taffs wrote: > > arm-linux-tools-20070808 looks like it was built with > glibc-2.3.6 does that mean uClibc cant be selected / used > within uClinux make menuconfig when using this tool chain ? > > The libc in the toolchain does't matter when compiling the > uClinux-dist. > It is completely self contained. you can (and should) > select uClibc when > compiling for non-MMU targets.
