qnx version

QNX USERS QNX2 and QNX4
1

I am using qnx 4.25. I am accessing qnx box available to me remotely using kermit( K95). I have few very simple questions, which I find difficult for qnx but am familiar with their linux counterparts.

  1. How can I know version of my qnx so that I dont believe what I am told and can be sure it is indeed qnx 4.25
  2. How can I set my core file size to unlimited as I am not able to use ulimit -c unlimited here. and I see no response (not even error) for ulimit -a
  3. Can any body send me a link for details of using gdb after installing it as I dont see gdb installed on my qnx box but from googling I think I can use it here.

Any help in this regard will be greatly appreciated.

Thanks and Regards
Bhawna

You can see the version of the kernel and drivers etc. on QNX4 using:

=> sin ve

You can also use the following command to get some info:
=> uname -a

I am not sure if GDB is available for QNX4. We are using the Watcom compiler and debugger. You have to buy them separately…
