It helps when the real requirements are clear.

Each function may have some inputs and return some outputs depending on the underlying physical description, e. You should compensate for this by writing ddlopen wrapper calls to wrap the calls to your C interface. In fact, that is not always simple and needs some explanation. Of course, I have used the search but have not found any directly linked answer.

Feedback Feedback is most certainly welcome for this document. A normal user could think this advice applies to normal shard libraries aka dynamically loaded mini-howti which in my opinion is not the case. Get the name of the component or other details about it Get the number of how many inputs or outputs the component exposes Interrogate a component about a particular input our mini-nowto Connect inputs and outputs together and others And that’s just for setting up your graph.

Several modern operating systems allow dynamic loading of plugins. Let’s assume I want a dynamically loaded lib and not the “standard runtime”.

Email Required, but never shown. And libffi enables you to call functions whose signature is only known at runtime. Martin York k 66 You’ll need at least some culture about garbage collection. It simply tells the compiler to emit an unmangled name, ‘s all.

Are all the functions compiled into the executable, or are they in dynamic libraries on what platform?

C++ dlopen mini HOWTO – Introduction •

I assume to have a library of physical models functions within classes. Loki I see what you’re saying, but to me I’ve always found that using extern “C” for exactly this reason has been worth it; I don’t have to look at the symbols in the binaries so I can look them mini-hpwto at runtime, and if I have say configuration files which refer to these names I don’t have to worry about them changing if we change compilers.

Now, the idea dkopen to provide the user a framework which allows him to compose any f according to his needs, i. Proceed with caution, and although this is highly unlikely, the author s do not take any responsibility. What do I overlook? Jan 20 ’12 at And that’s just for setting up your graph.

This is a strong architectural design decision. Post as a guest Name. The original question was about shared libraries only via comments did we find it was about plugin shared libraries.

To give you a better understanding here is a very simplified example: You build on one platform and use on other platforms? The document was last updated in You know who you are! These containers can also hold other components cf. If the compiler is upgraded something bigger has happened I am re-build all my libraries anyway.

Is this still relevant for dynamic libraries? Three Easy Pieces for a good overview. Therefore, the framework provides a container class.

In all these approaches, memory management is a significant concern it is a “whole program” property, and what actually is the “envelope” of your program is “changing”. You could use some JIT compilation library like libgccjit or asmjit.

Each function will have a specific name and all components must have those functions.

Sign up using Facebook. P Please think about why that isn’t good enough and update the question. Notice that some programming languages, notably Common Lisp and Smalltalkare more friendly to the idea of runtime importing functions.
