Looking at the dumpOSC.c source file, there is nothing special
happening for the output.  It simply uses printf to the standard
output.  There is even an fflush(stdout) in one place to ensure that
the output is printed immediately after the message is received.

I just tested the following code (Ubuntu Linux), and I was able to
send it messages from PureData.  It printed them out to the terminal
as expected.

#include <stdio.h>

int main()
{
    char buf[1024];
    int pos=0;
    char c;
    FILE* f = popen("./dumpOSC 8000", "r");
    if (!f) {
        printf("Couldn't execute dumpOSC.\n");
        return 1;
    }

    while (fgets(buf, 1024, f)) {
        printf("%s", buf);
    }

    return 0;
}
