I've installed valgrind-3.9.0 on linux Slitaz-2.6.37 (32bit) booted on virtualbox but when i try to use it on a C program (any a.out file), i encounter this error:

valgrind: that exports the above-named function using the standards

valgrind: to intall for fix (1) is called
valgrind:
valgrind: On Debian, Ubuntu: libc6-dbg
valgrind: On SuSe, openSuSe, Fedora, RHEL: glibc-debuginfo
I'm fairly new to Linux and Valgrind but it seems that i need a specific package. This error does not report after which name the package is labeled on my distro (Slitaz). Slitaz does not have the apt-get command nor it's in my intensions to install it (if possible).
I tried to use, with superuser privileges, the command "tazpkg get-install " with any possible combination of libc6-dbg and glibc... I' ve already searched for a solution on the web without any result. Thanks for your time and attention

Hey Mr. Hyde,
I ran into the exact same issue that you did. I also saw your post at Stack Exchange. Any luck finding a solution?
I tried to take matters into my own hands, and I royally hosed my system trying to build glibc-2.19 from source (as described here: http://forum.slitaz.org/topic/broken-slitaz-40-bootinit-caused-by-faulty-glibc-or-coreutils-kernel-2637-cooking).
But I'm curious to find out what you've learned.

-- Do not ship your Linux distro with a completely stripped /lib/ld.so. At least leave the debugging symbol names on -- line number info isn't necessary.
-- Don't strip the debug info off lib/valgrind/$platform/vgpreload*.so in the installation tree.
-- Don't strip symbols from lib/valgrind/* in the installation tree.
-- Please test the final installation works by running it on something huge.

I've run into the same problem. I downloaded ld-2.14.1.so from alanyih and changed ld-linux.so.2 so that it pointed to the new library...and my system stopped booting.
ld-linux.so.2 originally pointed to ld-2.13.so. I thought I could replace that with a 2.14 library but seems not....
Any advice? Should I (somehow) try recompiling ld-2.13.so with debug info?

@new_u
Sorry!
You are right.
slitaz-2.6.37 should be use ld-2.13.so
Please try docker ( boot2docker.iso )

Thank for the reply alanyih! I'm not sure how docker is related to the stripped ld issue though?

Thanks Mojo!!! Much appreciated

Well...I thought this time it would work but if I use the new library Slitaz doesn't boot.
I renamed the original library to ld-2.13.so__ and copied the new library to /lib. That should be it?
(the hash of my downloaded file is OK)

Slitaz-4.0 full install
Rename existing ld-2.13.so to ld-2.13.so~
wget http://people.slitaz.org/~mojo/stuff/ld-2.13.so
ls -l /lib/ld-2.13.so <=verify permissions 755 root:root
ls -l /lib/ld-linux.so.2 <=verify symlink to /lib/ld-2.13.so
ldconfig <=updates cache
Boots OK.

Thanks again Mojo! I feel so stupid. The permissions and owner/group were wrong. NOW valgrind works
(Maybe ld-2.14 also works on Slitaz 4.0)
