Subject: How to compile glibc debuginfo: valgrind complaining

Hi,

Stats: Fedora 12 base minimal install, compiled glibc 2.10.1, gcc-4.4.2, binutils-2.19. Followed Linux from Scratch directions (more or less). Did not replace system libraries. Valgrind compiled with new tool chain.

This question is actually a prelude to a wider issue that may come in another cry for help. :)

Valgrind 3.5.0 is reporting the following message:

valgrind:  Fatal error at startup: a function redirection
valgrind:  which is mandatory for this platform-tool combination
valgrind:  cannot be set up.  Details of the redirection are:
valgrind:
valgrind:  A must-be-redirected function
valgrind:  whose name matches the pattern:      strlen
valgrind:  in an object with soname matching:   ld-linux-x86-64.so.2
valgrind:  was not found whilst processing
valgrind:  symbols from the object with soname: ld-linux-x86-64.so.2
valgrind:
valgrind:  Possible fixes: (1, short term): install glibc's debuginfo
valgrind:  package on this machine.  (2, longer term): ask the packagers
valgrind:  for your Linux distribution to please in future ship a non-
valgrind:  stripped ld.so (or whatever the dynamic linker .so is called)
valgrind:  that exports the above-named function using the standard
valgrind:  calling conventions for this platform.
valgrind:
valgrind:  Cannot continue -- exiting now.  Sorry.

The command 'file' output:

$file /usr/local/tools-0.0.2/lib/libc-2.10.1.so /usr/local/tools-0.0.2/lib/libc-2.10.1.so: ELF 64-bit LSB shared object, x86-64, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.33, not stripped

This output seems to say the dynamic linker is not stripped, so I must be missing something.

I am impressed I may have not configured part of the tool chain build correctly.

Thanks,
Chris Swanson

I tried to give HTML pages to the build scripts but the MAILER kicked it back. I'll post them here:
