Prerequisites

• Linux or MacOS
• Optionally: the C++ IDE juCi++
  • If you do not install juCi++, you will need to install additional dependencies such as g++, cmake and make

Installing dependencies

In juCi++, choose Start in the Debug menu.

Backtrace of a stopped process

Select Run Command in the Debug menu, and run bt.

Alternative 2

In a terminal:

cd build                             # In case you are not in this folder already
mkdir debug
cd debug
cmake -DCMAKE_BUILD_TYPE=Debug ../..
make
gdb ./web_server                     # In MacOS, instead use: lldb ./web_server
run
