# How to Build
|
||||
|
||||
- On Ubuntu 14.04+
|
||||
|
||||
```bash
|
||||
g++ -I ../imgui main.cpp imgui_impl_a5.cpp ../imgui/imgui.cpp -lallegro -lallegro_primitives
|
||||
```
|
||||
|
||||
- On Windows with Visual Studio's CLI
|
||||
|
||||
\<a5path\> is your allegro5 folder.
|
||||
|
||||
```
|
||||
cl /MD /I <a5path\include> /I ..\imgui main.cpp imgui_impl_a5.cpp ..\imgui\imgui.cpp /link /LIBPATH:<a5path\lib> allegro-5.0.10-monolith-md.lib user32.lib
