In this article, we will see how to solve snort error daq_static library not found. Recently, I was trying to install Snort from source code on my Ubuntu Linux system but as soon as I ran configure script, after sometime it failed with error daq_static library not found. After looking into the error further, I understood the problem and then decided to write an article about this to share the solution steps so that in case if you are also facing the same error then it will help you as well.

As I said, while following the installation steps, when I tried running ./configure script then after sometime I noticed ERROR! daq_static library not found on the output as you can see below.
cyberithub@ubuntu:~/snort-2.9.20$ ./configure ........................................... checking for eth_set in -ldnet... no checking for eth_set in -ldumbnet... yes checking for dlsym in -ldl... yes ./configure: line 13016: daq-modules-config: command not found checking for daq_load_modules in -ldaq_static... no ERROR! daq_static library not found, go get it from http://www.snort.org/.
While above error could occur due to multiple reasons but the most obvious one is that it is not able to find daq_load_modules due to missing libdaq-dev package in your system. So to solve the error, you just have to install this package by using sudo apt-get install libdaq-dev command as shown below.
cyberithub@ubuntu:~$ sudo apt-get install libdaq-dev [sudo] password for cyberithub: Reading package lists... Done Building dependency tree Reading state information...

After installing the package successfully, if you now run ./configure script again then this time you will notice that it is able to find daq_load_modules and proceed as expected. This also confirms that the original error daq_static library not found is resolved now as evident from below output.

Sometimes it is also possible that even after following above steps, you might be facing the same error again. In that case, I would request you to please write me in the comment box so that we can work together to solve this daq_static library not found error.
