Downloaded the latest version, Valgrind 3.7.0, untarred it to create a folder "Valgrind-3.7.0"
Now, what I did was export gcc for compatibility with the target machine and configured to disable tls and give the host.
Also I made a C Program "leak.c" and its object file "a.out" compiled with the following command
export CC=/usr/local/netd_tools_v1/powerpc/bin/powerpc-linux-gnu-gcc leak.c
so
a. export CC=/usr/local/netd_tools_v1/powerpc/bin/powerpc-linux-gnu-gcc
b. ./configure --prefix=/netd --host=powerpc-linux --disable-tls
c. make
d. make install
- Link the library path and valgrind executable
(go to /netd/lib and do
ln –s /u/netd/lib/valgrind THEN
goto /netd/usr/sbin and
do ln –s /u/netd/bin/valgrind)
Some files were made in "Valgrind-3.7.0" and a folder "netd" was formed.
"netd" contained "lib", "bin", "share" and "include"
(/netd/lib and /netd/usr/sbin are project specific directories)
Copied these files (files in "netd") into the Target Machine and ran Valgrind on the file "a.out" by the following command :
valgrind --log-file=/u/july5.txt --leak-check=summary --tool=memcheck ./a.out
(`/u` is the mount point, `july5` is the log file)
The output shows 0 leaks reported
int main()
{
printf("I am leaking.");
int *a =(int *) malloc(100);
return 0;
}
This ran on linux just fine and reported errors.
If this would have worked, then I would have run Valgrind on project specific processes.
