Thanks,

Could you be more precise about your advices...

I have done some tests:

Solution 1 : "set new-console"
---------------------------
I suppose it is the "set new-console on" of gdb ("on" is the default mode in
mingw/gdb). I have tried to insert this line into a file "c:/gdbinit.txt"
and I set "c:/gdbinit.txt" in "gdb command set" in "launch
configuration>debugger". But "c:/gdbinit.txt" is not loaded by gdb under
eclipse (bug ?) (see traces #1)

Note : when I set "new-console" manually (outside eclipse), I have perfect
output (see trace #2)

Note : this solution is not as much pleasant than output in eclipse console
for simple test programs (especially, it requires "getchar()" function to
prevent automatic closing of the console window, ...) 

Is there a methode to set "new-console to on" by an another way ?

Solution 2 : new console with an other method
---------------------------------------------
http://dev.eclipse.org/newslists/news.eclipse.tools.cdt/msg14587.html

In previous link, it is recommended to use "-Wl,-subsystem,console" option
in gcc.

It doesn't work in my environment... (it still use eclipse console)

My eclipse "build" console:

      **** Rebuild of configuration Debug for project test ****
      **** Internal Builder is used for build               ****
      g++ -O0 -g -c -osrc\test.o ..\src\test.cpp
      g++ -Wl,-subsystem,console -otest.exe src\test.o
      Build complete for project test
      Time consumed: 422  ms.  
 


Solution 3 : pipes
------------------

Do you mean to redirect output to a file and to watch file after execution ?

Do you mean to do something inside eclipse gui or outside eclipse ?
