[ndnSIM] [EXT] Problem linking when building ndnSIM

Hi Eric

Most likely your system was out of memory, so that the kernel killed the
linker process.
You can confirm this condition by:

   1. Run dmesg | tail -50 right after the error occurs.
   2. Look for messages containing "oom killer".

To solve this problem, ensure your system has at least 4GB of available RAM
per CPU core.
If you have more CPU cores than available RAM, you can reduce the number of
parallel tasks.
For example, if you have only 8GB RAM but 4 CPU cores, you should limit to
2 parallel tasks: ./waf -j2

Yours, Junxiao
