STRUCT_ALIGN in VLib

Dave Winder15947

When I compile an application using VLIB for the C64+, I get an error that the

#pragma STRUCT_ALIGN is an unrecognized pragma

Why is this?

I have tried using both the C style and C++ style since I am actually compiling in C++ mode. But both are reported as unrecognized.

The STRUCT_ALIGN pragma is only supported in C (implying it is not supported in C++), as per section 6.8.19 of SPRU187o, I suspect this may be your problem. If you could convert your project to use C instead of C++ than you should be able to use the pragma.

Thanks Bernie. I missed that. Interesting the CCS help files give a C and C++ version syntax. I looked there first.

Anyway, I dont need the Kalman filter data structures which is where this is used in VLIB.So I can avoid the issue.

I can not convert (easily) to C due to a heavy use of templates in some 3rd party supplied code.

Glad I could help, I will have to take a look in the latest CCS help files to see if that C++ syntax is still in there, that sounds like a documentation bug. Several of the other pragmas have a C and C++ version so this may just have been overlooked, or possibly it was an option in some other CGT release (perhaps another device).
