[vanhauser-thc]

can you please try to make a bug report with sufficient information? what libssh packages are installed? where? what is your OS? etc.

[vanhauser-thc]

If you do not add to the bug report I will close it

Hi,I think I'm having the same problem. My OS is Ubuntu 14.04 I installed environment by "apt-get install libssl-dev libssh-dev libidn11-dev libpcre3-dev libgtk2.0-dev libmysqlclient-dev libpq-dev libsvn-dev firebird2.1-dev libncp-dev libncurses5-dev" when I make thc-hydra-8.3, I encountered this problem:

Any help will be grateful, THANKS!

[vanhauser-thc]

I only have a Kali Rolling and Ubuntu 16.04 available and both do not have that issue.

My guess: you have libssh2 or another library like that installed which makes this fail.

[Evi1CLAY]

I just installed these two packages : libssh-4 libssh-dev, :-( I will test on Ubuntu 16.04. Another question: How do I get Hydra-8.4-dev? I did't find it . ths~

[Evi1CLAY]

Work well on Ubuntu 16.04 :+1:

Hydra 8.4

[vanhauser-thc]

dunno what is wrong with your system. can you please send the output of ./configure --debug and the last gcc line that is exected? (the very long one)

[hostgame]

I have installed hydra 6.4 by this manual and after that version 8.4 compiles well
