The document discusses AmigoCloud, an enterprise mapping platform that allows for mobile cross-platform development in C++. It describes how AmigoCloud uses 95% common C++ code and 5% platform-specific code to build applications for iOS, Android, and other platforms. It also details AmigoCloud's custom build system called AmigoMake, which handles compiling C++ code and dependencies for different platforms.

5. DATA COLLECTION MOBILE APPLICATION
AMIGOCLOUD: MOBILE CROSS-PLATFORM DEVELOPMENT IN C++
Android iOS
- Map Rendering (OpenGL)
- Data Collection Forms are user-
customizable (through HTML +
JavaScript).
- Intensive Geospatial Operations
- Common Code between all
platforms
a) 95% C++ code
b) 5% platform-specific code
- iOS, Android, OSX, Linux,
Windows

6. HOW?
AMIGOCLOUD: MOBILE CROSS-PLATFORM DEVELOPMENT IN C++
- No third party framework
- Leverage POSIX
- C++ 11 codebase (e.g. threads, shared pointer types, lambdas, STL)
- GCC or Clang/LLVM
- Webkit
- Custom Build system to handle complexity of compiling (AmigoMake)...

8. BUILD SYSTEM: AMIGOMAKE
AMIGOCLOUD: MOBILE CROSS-PLATFORM DEVELOPMENT IN C++
a) Open Source – built by us for us.
b) Python based
c) Downloads all external libraries (e.g. freetype, jpeg, sqlite, openssl, libcurl,
etc)
d) Trivial to add more dependencies
e) Builds it for the target system (can generate shared libs, static libs or
executables). Finds all the .c, .cpp, .m, .mm files and the headers and builds
it according to AmigoMakefile
Building dependencies is one of the most complex parts
of pulling this off. We wanted it to be easy.

9. BUILD SYSTEM: AMIGOMAKE
AMIGOCLOUD: MOBILE CROSS-PLATFORM DEVELOPMENT IN C++
iOS build (with external dependencies)
amigomake --all -a armv7 -a arm64 clean ios -v 8.1
Android build (with external dependencies)
amigomake --all android -n ~/android-ndk/ -v 14
X86 build (with external dependencies)
amigomake --all x86
Generate CMake config (e.g. to use with Intellij/CLion)
amigomake cmake x86

11. HOW DO YOU INTERACT WITH C++ IN iOS
AMIGOCLOUD: MOBILE CROSS-PLATFORM DEVELOPMENT IN C++
- Actually, we use Objective C++. Rename .m to .mm and you are good to
go!

12. HOW DO YOU INTERACT WITH C++ in Android
AMIGOCLOUD: MOBILE CROSS-PLATFORM DEVELOPMENT IN C++
- Java Native Interface (JNI)
Java Class
C++ Function Prototype
C++ Implementation

13. HOW DO YOU INTERACT WITH WEBKIT AND JAVASCRIPT
AMIGOCLOUD: MOBILE CROSS-PLATFORM DEVELOPMENT IN C++
- Through a bridge (i.e. implement a class in your native language and expose
it to JavaScript)
