Following the AWS Guide: https://aws.amazon.com/blogs/iot/how-to-bridge-mosquitto-mqtt-broker-to-aws-iot/ and I got to the step that has me install mosquitto.

//Update the list of repositories with one containing Mosquitto sudo wget http://download.opensuse.org/repositories/home:/oojah:/mqtt/CentOS_CentOS-7/home:oojah:mqtt.repo -O /etc/yum.repos.d/mqtt.repo //Install Mosquitto broker and Mosquitto command line tools sudo yum install mosquitto mosquitto-clients

However, the guide is so outdated that it does not mention anything about the missing libwebsockets library. I've spent roughly 4-5 hours on searching for an answer on how to manually install/link/setup the library but I have not been able to make anything work.

(1) Tried this
git clone https://github.com/warmcat/libwebsockets.git cd libwebsockets mkdir build cd build cmake .. -DCMAKE_C_COMPILER=/usr/bin/gcc make sudo make install

But yea that didn't work because CMAKE throws all kinds of errors like

CMake Error at /usr/share/cmake/Modules/CMakeDetermineSystem.cmake:99 (message): Could not find toolchain file: /tmp/mytoolchainfile Call Stack (most recent call first): CMakeLists.txt:131 (project) CMake Error: Error required internal CMake variable not set, cmake may be not be built correctly. Missing variable is: CMAKE_C_COMPILER_ENV_VAR CMake Error: Could not find cmake module file: /tmp/libwebsockets/build/CMakeFiles/2.8.12.2/CMakeCCompiler.cmake -- Configuring incomplete, errors occurred!

So I tried to set the CMAKE_C_COMPILER path to /usr/bin/gcc, which is where the compiler is installed and that didn't do anything either. In all honesty, I'm not super familiar with Linux, I'm just trying to make do the best I can. I could really use some guidance on how best to get library installed and linked into Linux. I do believe AWS runs a red-hat version of linux.

Thanks for your time!
