The attached script (wrapper/setup to crosstool.sh) gets me a toolchain sufficient to build the default-config ppc kernel (2.6.8.1, NPTL, gcc-3.4.2, glibc-2.3.3). It tweaks the patch Dan references below for a ppc-ism, then adds a patch (thanks Google!) to mask an issue that gcc-3.4.2 has with inline functions calling setjmp() ( see http://mirrors.mathematik.uni-bielefeld.de/pub/linux/suse/ftp.suse.com/pub/projects/powerpc/ftp.linuxppc64.org/pub/people/janis/old/README.20040130 ) The toolchain build fails near the end while linking build-glibc/elf/sln with undefined references to `_Unwind_Resume' and `__gcc_personality_v0' (which Google hints is/was a popular problem, but I don't have time to track it down). In any case, 'sln' isn't needed for kernel building, so it's good enough for me for now. ...jfree ======== On Tue, Oct 12, 2004 at 08:29:58AM -0700, Dan Kegel wrote: > Hi Stephen, > to build NPTL, you need to apply > contrib/crosstool-0.28-rc34-nptl_fixes.patch > Then see demo-x86_64-nptl.sh > > Enough people need this that I've been intending for two weeks to merge it > asap, > but I haven't gotten around to it. > > That patch was only tested for x86, but ppc32 shouldn't be any > harder, right? :-) > - Dan > > Stephen Warren wrote: > >Hi.
