But not all of them. A few deviations from the instructions +found in the LFS books are needed to build a PowerPC LFS system. + +This hint describes how to build LFS versions 5.1.1, 6.3, 6.5, +6.6 & 6.7 for PowerPC. + +This hint does not describe how to build the PowerPC kernel or boot +loader. Those are left as an exercise for the reader. The CLFS +book may be helpful in learning how to build a bootloader and kernel +for a PowerPC system. + +This hint only describes building PowerPC 32bit architecture. It does +not describe how to build LFS for the PowerPC 64 bit machines. + +PREREQUISITES: + +A PowerPC machine running the proper tool set is required to build LFS. +A PowerPC eMAC G4 running Fedora 10 is known to work with the instructions +in this hint (except for building LFS 5.1.1). + +Familiarity with building LFS for x86 machines. The reader ought to +have built LFS for x86 at least once prior to attempting a build for +PowerPC. + + +HINT: + +Always follow the instructions in the LFS book exactly as written +except for the deviations as described in this hint... + +The dynamic linker for PowerPC is ld.so.1. So, in all cases, instead +of using the string 'ld-linux.so.2' as found in the LFS book, use +'ld.so.1' instead. + +Always skip the build step of the grub bootloader package. +It is not needed on PowerPC and typically will not even compile for +PowerPC. + +LFS provides a 'uname' patch for the coreutils package which is applied +during the Chapter 6 build of coreutils. The 'uname' patch does not +work for PowerPC and the build of coreutils will fail if it is applied. +This patch does not appear to be crucial so simply do not apply it during +building of coreutils. If the fix provided by the 'uname' patch is +important to the reader, a processor independent version of it might be +available somewhere in the CLFS download area. + +JHALFS can be used to build LFS for PowerPC but the user must download +the LFS book, apply the needed PowerPC changes to it, and then point JHALFS +at the modified book to use as a 'working copy'. + +LFS 5.1.1 specific instructions: + + (5.1.1 is still interesting cause it is the last of the 2.4 based + LFS books) + + Chap 5 & 6: + + 1) use ld.so.1 instead of ld-linux.so.2 when patching gcc specs file. + + Chap 5: + + 2) The gcc pass 2 specs patch is broken on PowerPC. + Instead of the patch, you have to go find and fix up the sysv4.h + file up by hand. + + Chap 6: + + 3) Skip the coreutils uname patch. + + 4) Skip grub bootloader build on ppc. + + (Fedora 10 does not work for building LFS 5.1.1. You'll need to + find an older PowerPC distro to build 5.1.1.) + +LFS 6.3 specific instructions: + + The attached patch "lfs-6.3bookforppc.patch" can be applied to the + LFS 6.3 release book to create a LFS 6.3 book that will build for + PowerPC. (It also contains some other changes not related to PowerPC). + +LFS 6.4 does not build for PowerPC due to tool chain issues and it cannot + be easily made to do so. + +LFS 6.5 and LFS 6.6 build for PowerPC without any deviations from the book. + +LFS 6.7: + + When building zlib in Chapter 6, omit '-mstackrealign' from the + definition of CFLAGS. It is an unsupported compiler option on + PowerPC. + +LFS 6.8: + + 6.8 is not yet released and so it is too early to say for sure but at + this time, it looks like it may build for PowerPC with the only + needed deviation being as described above for LFS 6.7. + + +LITERATURE : + +NA + +ACKNOWLEDGEMENTS: + +The excellent work of the LFS development team. + +CHANGELOG: + +[2011-02-12] + +Initial version. -- http://linuxfromscratch.org/mailman/listinfo/hints FAQ: http://www.linuxfromscratch.org/faq/ Unsubscribe: See the above information page
