Hi, I am using GDB 5.0 on Cygwin(NT).I have tried debugging threads but I am not able to do so.. Is such a debugging option available in GDB 5.0 for Cygwin(NT)? I wrote a pgm which forked another process. After the forking was performed I typed the follwing gdb command. info threads I got a list of two threads.(a * indicating my active thread) But when I tired to switch to the other thread using the thread gdb command. I was switched to the other task but..I could not debug it.. I got an error saying cannot find bounds of function.. I tried the same using pthread_create function in cygwin..But it too did not work. Can such debugging be donw in my platform? Since the commands are available..Should it not be working? Should I compile my program with special flags other than -g? Hope u can help me.
