Matlab Compiler - Invalid MEX-file for 'sqp' in optimization toolbox

I am generating standalone application that allows the user to select which method they want the optimization toolbox to use at the command line. if the user selects 'active-set', it works fine. If the user selects 'interior-point', it works fine. If they select 'sqp' I get the following error. (In the .m file this standalone is built on, all three are fine.)

Invalid MEX-file
'/Users/phillicl/.mcrCache7.13/fillin21/toolbox/optim/optim/private/activesetqp.mexmaci64':

Can this be addressed?

Thanks

Hi,

@Kaustubha: very unlikely. If the function is missing you would get an unkown function error!!!

Seems more like a missing dependency. Since you are using 10a see this Bug in which you ran into and apply the patch (or upgrade to 10b and newer):

Ah. Makes sense. :)

I upgraded to Matlab R2011a and still had this issue.

Caused by:

Invalid MEX-file

'/Users/phillicl/.mcrCache7.15/fillin0/toolbox/optim/optim/private/activesetqp.mexmaci64':

dlopen(/Users/phillicl/.mcrCache7.15/fillin0/toolbox/optim/optim/private/activesetqp.mexmaci64,

So I basically kept copying files just like the bug report suggested until the issue went away

I copied

libmwoptimutil.dylib

libmwbarrierqplp.dylib

and then it worked.

This will be a little annoying for deployment...

FYI, I was working with matlab 2011b in a linux environment and it did not have this issue.

Seems like a case of MATLAB Compiler not adding the function 'activesetqp' to the compiled archive. Perhaps you can try using the %#function pragma (%#function activesetqp) in the function being compiled? Not sure if this works for private functions (activesetqp is private), but its worth a shot.

(Also, as a side experiment, I wonder what happens if you try to deploy a function that uses 'sqp' directly, ie. without the user making a choice)
