Valgrind for ARM with Linaro Toolchain requiring libc6-dbg with Buildroot
I cross compiled Valgrind (http://valgrind.org/downloads/valgrind-3.8.1.tar.bz2) for ARM using the following commands with the Linaro Toolchain on my Ubuntu 10.04 host ( I am using Buildroot ):
export PATH=$PATH:/home/user/toolchain/linaro/bin
CC=arm-linux-gnueabi-gcc CFLAGS=-I/home/user/toolchain/linaro/arm-linux-gnueabi/libc/usr/include LDFLAGS=-L/home/user/toolchain/linaro/arm-linux-gnueabi/libc/usr/lib ./configure --prefix=/opt/valgrind --host=armv7-none-linux-gnueabi --target=arm-none-linux-gnueabi --build=i386-ubuntu-linux
make
sudo make install
When I copy the binaries to my ARM target board, I get the following error:
==413== Memcheck, a memory error detector

My Linaro Toolchain Version is:
gcc version 4.7.1 20120402 (prerelease) (crosstool-NG linaro-1.13.1-2012.04-20120426 - Linaro GCC 2012.04)
I've searched around on Google but cannot find a solution to this. How can I get Valgrind to work on my target board? I use Buildroot to build my system but libc6-dbg is not a package I can find in the build system. Is there some directory or files I need to copy from the toolchain sysroot? Thanks -
The command I am using to run Valgrind is shown here:
# which valgrind
/usr/bin/valgrind
# valgrind /home/user/MyQtApp

Answer
So you are using Buildroot or OpenEmbedded to build your Libc?
If it is OE then you should have libc6-dbg package available in local repository (TMPDIR/deploy/ipk). Or add "dbg-pkgs" into IMAGE_FEATURES and rebuild your image.
Glibc 2.12 shows that you are using old version of OpenEmbedded. But even this should give you libc6-dbg package.
Can not help with Buildroot as never used it.
