Dear all,
I want to install wgsim on my Ubuntu 16.04 machine; I downloaded the zip file wgsim from the website, unpack it and moved it to /usr/local/lib/. I then ran the suggested commands (both with gcc and make) and I got:
:/usr/local/lib/wgsim$ sudo make wgsim
[sudo] password :
cc wgsim.c -o wgsim

What I am missing? are there some dependencies?
Thanks

Get from the github readme:
I ran
gcc -o wgsim wgsim.c -lm -lz
and a wgsim command is created but when i run it on an example from the web i got:Don't run user program using
sudo
. Not a good practice.If you are trying to run
wgsim
from the directory where it is present then you need to either do it explicitly as./wgsim
or add the directory (inbash
shell) where wgsim is located to$PATH
simply by doingexport PATH=$PATH:/path_to_wgsim
You can add this line to~/.profile
file make the change permanent.
