 We can use valgrind to create a callgraph as follows. After compiling the code with the -pg option run:
 <code>
-valgrind --dsymutil=no --tool=callgrind myexec.x
+valgrind --dsymutil=yes --tool=callgrind myexec.x
+</code>
+After the run, obtained ''callgrind.out.1234'' file can be processed with gprof2dot as:
+<code>
+gprof2dot.py -n0 -e0 ./callgrind.out.1992 -f callgrind > callgrind.out.1234.dot
+</code>
+Then use dot to create the actual graph:
+<code>
+dot -Tpng out.dot -o out.png
 </code>
+In the case you want to filter out the system calls from the graph, the solution of : [[https://stackoverflow.com/a/7774742]] works like a charm.
