Support of C++ as implementation language for AADL subprograms

[Stachelbeck]

I created a simple AADL v2.1 Rate Monitonic Scheduling single a single thread calling one subprogram. The subprogram is written in C++ (I all so developed a C version of the same subprogram). When staring ocarina to generate code I receive the following error message from ocarina:

IDAeNetBusManagera.aadl:7:30 Backends: fatal error : This kind of subprogram is not supported SUBPROGRAM_UNKNOWN

AADL v2.1 specification:

subprogram BCMgr properties Source_Language => (CPP); Source_Name => "bcmgr"; Source_Text => ("bcmgr.cpp"); end BCMgr;

My ocarina verion is dated 12-17-2012.

This is the C version in which ocaina will generate code and its generated and user created code (bcmgr.c) will compile and execute on the targeted machine.

subprogram BCMgr properties Source_Language => (C); Source_Name => "bcmgr"; Source_Text => ("bcmgr.c"); end BCMgr;

Thanks,

Kenneth

Kenneth,

I just committed b26b470805f83631e6ff78352c885fbae6e33551 that provides early support for this feature: tested on a similar testcase as yours. Some more work is necessary for C++ subprograms used in in event ports and call sequence.

Given issue #12, I consider this ticket closed.

Hi,

You may start with resources from http://www.openaadl.org/osate-ocarina.html and the following examples: http://www.openaadl.org/aadlib.html

thanks, but is there any other resources on how to use code generation?

Using code generation is nothing more than pointing the root system to the tool, as detailed in the first link. Unless you have more precise question, I strongly suggest you try first.

Also, please do not use old tickets to discuss unrelated issues.
