A way to include the all source files so my professor can run them using only gcc

[PhKhang]

Our assignment is to create a C++ game that runs entirely in the terminal, particularly Windows Terminal. And components like Menu and V-flow would be a perfect fit for the game.

All FTXUI examples run flawlessly on Windows Terminal after using CMake and make to build, but our game can only use g++ commands to compile and run. Therefore, I was wondering if there is a way to include the source files of some modules and link them like regular header files so that the entire game and FTXUI components can be compiled with g++ only.

I tried putting include and lib folders inside our directory and change all the #include paths to the correct relative path of all the files that ftxui-starter calls for but it gave errors like this:

Thanks in advance and thanks for making this amazing library.

Hello, I think you forgot to link against ftxui libraries. Could you try adding -lftxui-screen -lftxui-dom -lftxui-component -lftxui-dom -lftxui-screen

FYI: Cmake generate commands like those:

Build

/usr/bin/c++ \
  -std=c++17
  -I/usr/local/include/ftxui/include \
  -o main.cpp.o \
  -c main.cpp 

Link

/usr/bin/c++ \
  main.cpp.o \
  -o main \
  /usr/local/lib/libftxui-screen.a \
  /usr/local/lib/libftxui-dom.a \
  /usr/local/lib/libftxui-component.a \
  /usr/local/lib/libftxui-dom.a \
  /usr/local/lib/libftxui-screen.a
