Hi!
I'm using Eclipse 3.1 with CDT 3.0 (M7) and Cygwin on Windows XP.
If I run a program more than once (i.e. I start a program, let it finish
and then start it again), I don't get console output except for the
first run.
My program (in C++):
#include <iostream>
int main()
{
std::cout << "Hello World!" << std::endl;
}
In C a corresponding program doesn't work either:
#include <stdio.h>
int main()
{
printf("Hello World!\n");
return 0;
}
The program runs in a managed make c project/c++ project.
Has anybody an idea how to solve this problem?
Even if I fflush(stdout); it doesn't work.
Best Regards,
Steffen

Yea, that's the same problem (I assume "Das Handle ist ungültig" means
"The file handle is invalid"). Check out the bugzilla link I posted in a
previous response for more detailed info, but the main idea is that it
seems as though in Eclipse 3.1RC2 they changed the way the launcher works
and I suspect they create a new thread which causes a race condition with
the thread that actually runs the application thus leading to the somewhat
inconsistent behavior. Anyways, this bug is crippling for me, so I have
to use Eclipse 3.1RC1 until the CDT guys find a way around it.
I briefly poked around in the C source code for the CDT plugin (where the
read0 function is located), but I don't have the time to setup a JNI
development environment to do any real debugging, hopefully someone else
will be able to fix this.
