I am stuck already and I havent even started !!! I have downloaded binutils-2.19.tar.gz gcc-4.4.1.tar.gz
then I get stuck, do I need glibc or uclibc, I would like to build uboot with the same tool chain so which one do I need to use ? If I use glibs-2.10.1 (the newest) do I need to use linuxthreads as this is no longer supported ? or do I need to use NPTL (its replacement)? Finally which version of elf2flt do I need to use ? elf2flt-20060708.tar.gz was used to create arm-linux-tools-20070808 should I use that one ? is there a newer version ? should I use that ? sorry for all the newbie toolchain questions ;-( --- On Tue, 11/24/09, steven taffs <steventa...@yahoo.com> wrote: > From: steven taffs <steventa...@yahoo.com> > Subject: Re: [uClinux-dev] ARM support > To: "uClinux development list" <uclinux-dev@uclinux.org> > Date: Tuesday, November 24, 2009, 12:36 PM > ok if I go to the codesourcery web > site and choose the following toolchain > > ARM uClinux and then choose cortex-m1 or cortex-m3 the > versions within their tool chain (currently) are > > GNU Binary utilities 2.19.51-sg++ > GNU C & C++ Compilers 4.4.1-sg++ > GNU Debugger > 6.8.50-sg++ > uClibc C Library > 0.9.30-sg++ > > They use gcc 4.4.1 because it fully supports the latest and > greatest ARMv7 cores (ie cortex).
