Why do I have a LINKING APPLICATION failure? (E) #A0307-D Symbol:

I have a real-time multi-processor application including a number of s-functions which I have been able to compile fine using matlab 2006b on a windows XP PC. But when trying to build using matlab 2008b on windows7(32bit) the build is failing with the following error:

LINKING APPLICATION ...

........etc........

*LINKING FAILED (1)* 

MAKE PROCESS ABORTED

being as this model built fine on my XP platform I'm sure it is a compatibility issue somewhere but I struggling to see where the issue is.

The source code for the s-function .dll's has been compiled in visual studio 2008

Answer 1

So I have found the answer for this problem now. It turns out that matlab 2008b compilers no longer support the linking method used in my C-code. I have found a work around for now by changing the the configuration parameters from make rti to make_rti LNK_OPTS="-K0 -QmsA0314 -QmeA0329".

This let me build my model but I will need to update my linker method for the future.

I hope this might be useful if anyone else has the problem.

Hi

Have you any idea about those Linking application and "-K0 -QmsA0314 -QmeA0329" are specific to your model or not?

Thanks Ayoub

Hello,

Before, I was building my model without any problem. But now, I am taking the following error.

Do you have any idea regarding what might cause it?
