C users will need to include the header file to use this API. dynamically loaded (DL) libraries should also consult the “C++ dlopen mini- HOWTO”. Shared Library Mini-Tutorial A shared library is a binary file that contains a set of callable C functions. Visit the dlopen man page for more information.

Another possibility is to embed some interpreter, like Lua or Guilein your program or write your own one, like Emacs did. It is a pain for mangled names.

Your physical models are built up of nodes you call them componentsand edges connectors in your naming. These containers can also hold other components cf. In mini-hwto first instance, the user should be able to set up a composition through importing an XML which defines the composition structure.

But you should consider the cons to exposing a C extern “C” interface. Do you plan on using multiple compilers?

It helps when the real requirements are clear. Use of a term in this document should not be regarded as affecting the validity of any trademark or service mark. dlppen

P Please think about why that isn’t good enough and update the question. But the question was not about runtime plugins I will change that in a second nor is the answer for plugins. The framework should provide functionalities to connect the outputs and inputs of different functions. There may be errors and inaccuracies, that could be damaging to your system.

You know who you are! You should compensate for this by writing extra wrapper calls to wrap the calls to your C interface Normal shared libraries Edit: Proceed with caution, and although this is highly unlikely, the author s do not take any responsibility.

This is a strong architectural design decision.

Let’s assume I want a dynamically loaded lib and not the “standard runtime”. Using it across several platforms without issues. We mean a library that is loaded vi dlopen and its symbols resolved via dlsym not a standard shard library that is dynamically loaded by the runtime system.

You’ll need additional functions defined to organize how your model is actually executed. 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 up at mini-hoeto, 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.


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

C++ dlopen mini HOWTO – Introduction •

Each function may have some inputs and return some outputs depending on the underlying physical description, e. Three Easy Pieces for a good overview. However, I am mnii-howto that the concept of “building objects during runtime” is very often required.

In my particular case, I am trying to create a dynamic library on OSX using libtool.
