Installation:
bzip2 -d valgrind-3.10.1.tar.bz2 tar -xf valgrind-3.10.1.tar then:
./configure make make install or simplier
sudo apt-get install valgrind How to run valgrind on that simple program example1.c
#include <stdlib.h> int main() { char *x = malloc(100); /* or, in C++, "char *x = new char[100] */ return 0; } Run:
valgrind --tool=memcheck --leak-check=yes example1 valgrind: example1: command not found Output from console:
valgrind: example1: command not found 2 Answers
It looks good. You only need to add a ./ before your executable. Without it, valgrind fails to find it and reports 'command not found'.
valgrind --tool=memcheck --leak-check=yes ./example1 ^ First, compile your C program (-g is extremely important; without debug info in the executable valgrind cannot tell you line numbers from the source code where the violations occur nor the original line of the allocations of the memory being violated.):
gcc -g example1.c -o example1 Then run valgrind on the executable:
valgrind --tool=memcheck --leak-check=yes ./example1
