In case you build the program as a "windowing application" (i.e., if you pass the -mwindows flag to gcc in the linking stage) the program's standard output and standard error don't show up anywhere (unless you explicitly redirect them to a pipe or file). That's why it's a bad idea to use -mwindows while developing an application. -mwindows should be turned of only when doing the the "release" build. > Have you any idea about this pb ?
