Errors while installing?

/usr/include/c++/5/string:38:28: fatal error: bits/c++config.h: No such file or directory - You don't have g++6 or g++6 multilib installed correctly

src/<any file>: fatal error: mathlib/vector.h: No such file or directory - You didn't download Source SDK. DO NOT DOWNLOAD CATHOOK USING "DOWNLOAD .ZIP" FROM GITHUB. USE git clone --recursive!

If you are using other distro, make sure to have g++-6, gdb, libc6 and build essentials installed.

Updating cathook

Run the update script in cathook folder.

Injection

sudo ./attach to attach to tf2 process (can take argument number 0-N - # of tf2 instance to attach to (for bots))

sudo ./attach-backtrace to attach and print backtrace if tf2 crashes. Some users reported that this method makes you get less FPS ingame.

Followbots

Followbot installation is quite complex and I won't cover it fully here. You have to have several user accounts ready to run tf2 - use google for that. You can ask someone in my discord server for help with installation. To control followbots, you need to download and install cathook-ipc-server.

Followbot server installation script

git clone --recursive https://github.com/nullifiedcat/cathook-ipc-server && \
cd cathook-ipc-server && \
make -j4

Updating script is the same as updating cathook

Running followbot server

./bin/cathook-ipc-server or ./bin/cathook-ipc-server &>/dev/null & to run it in background
