Procedure to build Valgrind binary for MIPS Architecture
Get latest Valgrind source code from (https://valgrind.org/downloads/)
wget
https://sourceware.org/pub/valgrind/valgrind-3.15.0.tar.bz2
Extract the tarball
tar -xvf valgrind-3.15.0.tar.bz2
On Bash prompt export below makefile defines
CC=/opt/CAVIUMsdk312/OCTEON-SDK/tools/bin/mips64-octeon-linux-gnu-gcc
CXX=/opt/CAVIUMsdk312/OCTEON-SDK/tools/bin/mips64-octeon-linux-gnu-g++
./configure --host=mips64-octeon-linux --target=mips64-octeon-linux
CFLAGS=" -march=octeon2 -mabi=64"
After configure is successfully executed do make in the directory
make​
To run Valgrind on target follow the below procedure
Copy the valgrind folder to target machine, Ex: /etc/user/
cd /etc/user/valgrind-3.15.0
touch /etc/user/valgrind-3.15.0/memcheck/default.supp
export VALGRIND_LIB=$PWD/memcheck/
export LD_LIBRARY_PATH=/usr/sbin/user/sharedobj/
./coregrind/valgrind --tool=memcheck --gen-suppressions=yes --leak-check=full -v
--track-origins=yes <Daemon>​
