c++ - How to run valgrind with basic c example? -

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 run valgrind on 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 console:

valgrind: example1: command not found

it looks good. need add ./ before executable. without it, valgrind fails find , reports 'command not found'.

valgrind --tool=memcheck --leak-check=yes ./example1                                           ^
