MATLAB JA Builder Failed with Mex File(2012b)

Hi all,

I am working on an optimization problem by using the BONMIN solver, which is third-party toolbox for nonlinear program analysis. I worked out a matlab program involving the invocation of the BONMIN solver. In my case, I need to package this program into Java pakcage, thus, I choose to use matlab ja builder to do so. However, I got the following error message:

The file 'F:\Documents\MATLAB\OPTI Toolbox\Solvers\bonmin\bonminCplex.mexw64' appears to be a MEX-file. It shadows the MATLAB file 'F:\Documents\MATLAB\OPTI Toolbox\Solvers\bonmin\bonminCplex.m' but will not execute properly at runtime, as it does not export a function named 'mexFunction.'

Is there anyone who have any idea about this problem?

Thanks!

Hi,

does it run successfully in MATLAB, so the error "only" happens when compiling into a Java component?

Thanks a lot for your comment. Yes, it works fine in matlab but error happens when matlab program are compiled to Java packcage. I have figured out the solution, which is to delete the "bonminCplex.mexw64" file. The reason is that such a file has some problem.
