# Configuration |
|
|
|
Dear ImGui outputs 16-bit vertex indices by default. |
|
Allegro doesn't support them natively, so we have two solutions: convert the indices manually in imgui_impl_allegro5.cpp, or compile imgui with 32-bit indices. |
|
You can either modify imconfig.h that comes with Dear ImGui (easier), or set a C++ preprocessor option IMGUI_USER_CONFIG to find to a filename. |
|
We are providing `imconfig_allegro5.h` that enables 32-bit indices. |
|
Note that the back-end supports _BOTH_ 16-bit and 32-bit indices, but 32-bit indices will be slightly faster as they won't require a manual conversion. |

# How to Build |
|
|
|
- On Ubuntu 14.04+ |
|
|
|
```bash |
|
g++ -DIMGUI_USER_CONFIG=\"examples/example_allegro5/imconfig_allegro5.h\" -I .. -I ../.. main.cpp imgui_impl_allegro5.cpp ../../imgui*.cpp -lallegro -lallegro_primitives -o allegro5_example |
|
``` |
|
|
|
- On Windows with Visual Studio's CLI |
|
|
|
``` |
|
set ALLEGRODIR=path_to_your_allegro5_folder |
|
cl /Zi /MD /I %ALLEGRODIR%\include /DIMGUI_USER_CONFIG=\"examples/example_allegro5/imconfig_allegro5.h\" /I .. /I ..\.. main.cpp imgui_impl_allegro5.cpp ..\..\imgui*.cpp /link /LIBPATH:%ALLEGRODIR%\lib allegro-5.0.10-monolith-md.lib user32.lib |
|
```
