Hello Jim,

i tried to build CLFS for a MIPS32 (big endian) platform which has no
MMU.
Following guide "Cross-Compiled Linux From Scratch - Embedded - Version
SVN-0.0.1-20081203-mips" it went well until i tried to configure uClibc
(chapter 6.8.1) with no-MMU. For that after "make oldconfig" i called
"make menuconfig" and switched the option "Target CPU has a memory
management unit (MMU)" to off. At the same time two lines upper the file
format changed from ELF to FDPIC ELF.
If i now try to comile uClibc i get the following output:

Is there a way to fix it ?
My assemby capabilities are not good enough to do that myself ;-)
Or am i doing that (switching MMU support off) at the wrong place ?
Uclibc has gone through a lot of changes. After I get CLFS standard
stabilized, I will concentrate on this book.
Could you give me a note when an update is available ?
regards
Petric
