26

No.  Although perhaps more background is useful:

27

28

uclibc-0.9.33(git)

29

host is an amd64 gentoo system

30

chroot is an i486/32bit gentoo system, used as a compile base for my

31

embedded Alix board

32

33

At the end of the install I see:

34

 * Messages for package sys-devel/gcc-4.4.6-r1:

35

36

 * Your x86 arch is not supported.

37

 * Hope you know what you are doing. Hardened will not work.

38

 * SSP has not been enabled by default

39

 * Your x86 arch is not supported.

40

 * Hope you know what you are doing. Hardened will not work.

41

 * Skipping libstdc++ manpage generation since you don't have doxygen

42

installed

43

 * Your x86 arch is not supported.

44

 * Hope you know what you are doing. Hardened will not work.

45

 * If you have issues with packages unable to locate libstdc++.la,

46

 * then try running 'fix_libtool_files.sh' on the old gcc versions.

49

I am thinking it's the uclibc which is the issue?  What else might I

50

worry about though...?
