during compiling older C++ code on Ubuntu 11.10 with mpic++ (Open MPI C++ wrapper compiler) I got this warning connected with int main(int argc, char **argv){...}:
main(int, char**) : warning: deprecated conversion from string constant to ‘char*’
I tried to edit the code to int main(int argc, const char *argv[]){...} but it did not help (contrary to e.g. this issue).
What did I wrong? How can I fix it?
