Hello,
I'm using linux kernel 2.6.15, uclibc-0.9.28 and toolchains (built using
buildroot) on embedded MIPS platform based od 4KEc CPU.
Simple examples compiled with gcc-4.0.3 or gcc-4.1.0 not producing
output. There is a piece of code:
for (i = 0; i < v.size(); i++)
{
out << v[i].s << " :\t"
<< v[i].t * (double(1000000)/n)/CLOCKS_PER_SEC
<< " ms"
<< endl;
// printf("%s :\t %2.3f ms\n", v[i].s, v[i].t *
(double(1000000)/n)/CLOCKS_PER_SEC);
}
When execute, output looks like this:
$./d_1++ 100000
./d_1 100000

Commented line with printf do produce output:

When using gcc-3.4.2 everything is OK.
