xgraph segfault when hdcpy button pressed
I made the following changes to "xtb.h" file in ns2.35, but it seems the problem still exists.
My os is ubuntu 13.04, later upgraded to ubuntu 13.10 (64 bits).
If I run the xgraph command, I can see the generated graphs, but when 'hdcpy' is pressed there is a segmentation fault (core dumped) message coming.
After the following changes, I did not reconfigure or make xgraph hdcpy in my system, because if I do then it says:
make:*** no rule to make target 'xgraph'. stop.
Please let me know if there is any other way to save/print the graphs.
