# How to Build
|
||
|
||
## Windows with Visual Studio's IDE
|
||
|
||
Use the provided project file (.vcxproj). Add to solution (imgui_examples.sln) if necessary.
|
||
|
||
## Windows with Visual Studio's CLI
|
||
|
||
Use build_win32.bat or directly:
|
||
```
|
||
set SDL2_DIR=path_to_your_sdl2_folder
|
||
cl /Zi /MD /utf-8 /I.. /I..\.. /I%SDL2_DIR%\include main.cpp ..\..\backends\imgui_impl_sdl2.cpp ..\..\backends\imgui_impl_opengl3.cpp ..\..\imgui*.cpp /FeDebug/example_sdl2_opengl3.exe /FoDebug/ /link /libpath:%SDL2_DIR%\lib\x86 SDL2.lib SDL2main.lib opengl32.lib /subsystem:console
|
||
# ^^ include paths ^^ source files ^^ output exe ^^ output dir ^^ libraries
|
||
# or for 64-bit:
|
||
cl /Zi /MD /utf-8 /I.. /I..\.. /I%SDL2_DIR%\include main.cpp ..\..\backends\imgui_impl_sdl2.cpp ..\..\backends\imgui_impl_opengl3.cpp ..\..\imgui*.cpp /FeDebug/example_sdl2_opengl3.exe /FoDebug/ /link /libpath:%SDL2_DIR%\lib\x64 SDL2.lib SDL2main.lib opengl32.lib /subsystem:console
|
||
```
|
||
|
||
## Linux and similar Unixes
|
||
|
||
Use our Makefile or directly:
|
||
```
|
||
c++ `sdl2-config --cflags` -I .. -I ../.. -I ../../backends
|
||
main.cpp ../../backends/imgui_impl_sdl2.cpp ../../backends/imgui_impl_opengl3.cpp ../../imgui*.cpp
|
||
`sdl2-config --libs` -lGL -ldl
|
||
```
|
||
|
||
## macOS
|
||
|
||
Use our Makefile or directly:
|
||
```
|
||
brew install sdl2
|
||
c++ `sdl2-config --cflags` -I .. -I ../.. -I ../../backends
|
||
main.cpp ../../backends/imgui_impl_sdl2.cpp ../../backends/imgui_impl_opengl3.cpp ../../imgui*.cpp
|
||
`sdl2-config --libs` -framework OpenGl -framework CoreFoundation
|
||
```
|
||
|
||
## Emscripten
|
||
|
||
**Building**
|
||
|
||
You need to install Emscripten from https://emscripten.org/docs/getting_started/downloads.html, and have the environment variables set, as described in https://emscripten.org/docs/getting_started/downloads.html#installation-instructions
|
||
|
||
- Depending on your configuration, in Windows you may need to run `emsdk/emsdk_env.bat` in your console to access the Emscripten command-line tools.
|
||
- You may also refer to our [Continuous Integration setup](https://github.com/ocornut/imgui/tree/master/.github/workflows) for Emscripten setup.
|
||
- Then build using `make -f Makefile.emscripten` while in the current directory.
|
||
|
||
**Running an Emscripten project**
|
||
|
||
To run on a local machine:
|
||
- `make -f Makefile.emscripten serve` will use Python3 to spawn a local webserver, you can then browse http://localhost:8000 to access your build.
|
||
- Otherwise, generally you will need a local webserver. Quoting [https://emscripten.org/docs/getting_started](https://emscripten.org/docs/getting_started/Tutorial.html#generating-html):<br>
|
||
_"Unfortunately several browsers (including Chrome, Safari, and Internet Explorer) do not support file:// [XHR](https://emscripten.org/docs/site/glossary.html#term-xhr) requests, and can’t load extra files needed by the HTML (like a .wasm file, or packaged file data as mentioned lower down). For these browsers you’ll need to serve the files using a [local webserver](https://emscripten.org/docs/getting_started/FAQ.html#faq-local-webserver) and then open http://localhost:8000/hello.html."_
|
||
- Emscripten SDK has a handy `emrun` command: `emrun web/index.html --browser firefox` which will spawn a temporary local webserver (in Firefox). See https://emscripten.org/docs/compiling/Running-html-files-with-emrun.html for details.
|
||
- You may use Python 3 builtin webserver: `python -m http.server -d web` (this is what `make serve` uses).
|
||
- You may use Python 2 builtin webserver: `cd web && python -m SimpleHTTPServer`.
|
||
- If you are accessing the files over a network, certain browsers, such as Firefox, will restrict Gamepad API access to secure contexts only (e.g. https only).
