Failing to install pcaprub in order to install packet-fu

I am trying to install packet-fu in ruby. Up to this point I have successfuly executed the following steps:

apt-get install ruby-dev
apt-get install libpcap-dev

But when I type:

gem install -r pcaprub

I get the following error:

# gem install pcaprub
Building native extensions. This could take a while...
ERROR:  Error installing pcaprub:

To see why this extension failed to compile, please check the mkmf.log which can be found here:

  /var/lib/gems/2.7.0/extensions/x86_64-linux/2.7.0/pcaprub-0.13.1/mkmf.log

extconf failed, exit code 1

Gem files will remain installed in /var/lib/gems/2.7.0/gems/pcaprub-0.13.1 for inspection.
Results logged to /var/lib/gems/2.7.0/extensions/x86_64-linux/2.7.0/pcaprub-0.13.1/gem_make.out

I've spent hours on this and would appreciate any direction.

Solution

  • For some reason, gcc was bit installed. Reinstalling it solved the issue.
