Yes, there are existing tools that do exactly this — generate C++ wrappers for Java classes. This makes use of Java APIs in C++ more transparent and enjoyable, with lower cost and risk. The one that I’ve used the most is JunC++ion. It’s mature, powerful and stable. The primary author is very nice, and very … Read more
I put your C++ function into header file as an inline function for testing. I was then able to construct a SWIG interface that does what you are looking for. It has two key parts. Firstly I wrote a typemap that will allow either a std::map, or a perl hash to be given as input … Read more
I know this question is a few weeks old but I just found it as I was researching a solution for myself. So I’ll take a stab at an answer, but I’ll warn in advance it may not be an attractive solution since swig interface files can be more complicated than hand coding the wrapper. … Read more
There’s two parts to this answer. First you need to expose your interface in Python in a way which allows Python implementations to override parts of it at will. Then you need to show your C++ program (in main how to call Python. Exposing the existing interface to Python: The first part is pretty easy … Read more
I’ve used both (for the same project): Boost is better integrated with the STL, and especially C++ exceptions. Also, its memory management mechanism (which tries to bridge C++ memory management and Python GC) is way more flexible than SWIG’s. However, SWIG has much better documentation, no external dependencies, and if you get the library wrapped … Read more
I can answer part of the question, why you’re getting the message. Something in your build process is invoking gcc on a C++ source file with the option -Wstrict-prototypes. For C and Objective-C, this causes the compiler to warn about old-style function declarations that don’t declare the types of arguments. For C++, this option doesn’t … Read more
I have a rich experience of using swig. SWIG claims that it is a rapid solution for wrapping things. But in real life… Cons: SWIG is developed to be general, for everyone and for 20+ languages. Generally, it leads to drawbacks: – needs configuration (SWIG .i templates), sometimes it is tricky, – lack of treatment … Read more
You should consider Boost.Python if you are not planning to generate bindings for other languages as well with swig. If you have a lot of functions and classes to bind, Py++ is a great tool that automatically generates the needed code to make the bindings. Pybindgen may also be an option, but it’s a new … Read more
I am currently working on an Android application which streams radio. I use native decoder library which is called aacdecoder. Everything was fine till app gets crash error on some Android devices. It was really annoying. Because app was perfectly plays radio streams almost all devices but Samsung S6 and S6 Edge. Crash report says … Read more
I agree with you that using typemap gets a little messy, but it is the right way to accomplish this task. You are also right that the SWIG documentation does not directly say that %pythonappend is incompatible with -builtin, but it is strongly implied: %pythonappend adds to the Python proxy class, and the Python proxy … Read more
