I am running emacs 24.1 on windows7 32bit with mginw32.When debugging my c/c++ application I can not give an iputting and can not see any output. For example: ... // line 1 ... // line 2 fgets(s,255,stdin); //line 3 ... // line 4 ... //line 5 i = 0; // line 6 Breakpoint is at this line. Then i started debugging: (gdb)r After executing the above command, it stopped at line 6 and didn't waitting for me to input values. I inputted values in input/output io buffer but nothing happend.Then I executed "(gdb)n" command,the debug toolbar icons became grey and i can not continue debugging my application.I tried to debug another application and it showed none output during the debugging. However, everything works like a charm in emacs 23.4 on windows7 with mingw32(emacs 24.1 on ubuntu 12.04 is also works very well).That'all, thank you.
