Try adding "-ldl" to the end of the command, ie..
gcc -Wall -pg conexiones.c -o conexiones -ldl
The explanation is that normally you link in the dynamic libc (libc.so) which automatically references the
dynamic loader library (libdl.so). When profiling, you link in the static libc (libc.a) which cannot automatically
grab the dynamic loader (libdl.so) so you have to specify it manually.
Mi original question, was:
