Subject: Need help on vlagrind debug symbols
Hi all,
We are facing an issue with valgrind tool 3.4.1 for the platform PPC-32.
While running valgrind on PPC32 target platform we could not see the debug
symbols.
The compilation steps that we did, are:
./configure --prefix=/valgrind-3.4.1 --host=powerpc-montavista-linux
CC=/linux_mvl_4.0.0/pro/devkit/ppc/82xx/bin/ppc_82xx-gcc
We copied our application, valgrind binary and lib files to an NFS server which
is linux platform.
We are running our application and valgrind binary flle on the target (PPC
platform) by mounting the NFS server and valgrind directory (where we copied
our binary files) on the target.
Our application is built under the '-g' option and we didn't strip it also. So
the application should have the debug symbols. we also tried to grep for a
function name in our application binary file and it is successful.
While executing the command,
./valgrind ./app
the following is a section of output we are getting,
>>
