[ECOS] uSTL hello world

[John Dallaway <john at dallaway dot org dot uk>]

Hi Uwe

There seems to be a problem with the uSTL hello world example given in
the uSTL documentation. The code produces no output. However, if I add a
printf() call after the cout.flush(), then I see _both_ messages.

This is not a case of printf() flushing the output - I can observe the
output from cout on the diagnostics channel _before_ the call to
printf() is made. In fact, if I move the printf() call to the start of
main(), then everything still works.

eCos was configured with default template, pc_i82559 target, ustl and
fileio packages added, no optimization. Debugging via RedBoot over ethernet.

Does the hello world example work unmodified on your own hardware platform?

--cut here--

#include <ustl.h>
//#include <stdio.h>
using namespace ustl;

int main (int argc, char* argv[])
{
    cout << "Hello world!\n";
    cout.flush();
//    printf("Hello printf!\n");
    return EXIT_SUCCESS;
}
