I think the reason is you don't install libevent: https://packages.ubuntu.com/artful/libevent-2.1-6.

[tazhate]

nope. it is installed.

Could you try:

cc -g -O2 -Wall -o tcpbench tcpbench.c -levent

Thanks!

Yes, according to this post, Ubuntu compiler has its own characteristic. Tomorrow I will modify the Makefile to adapt to Ubuntu and do some tests.

[NanXiao]

@tazhate I update the Makefile and close this issue, you can submit new issue once find other errors, thanks!
