Hi,

I'm using Cplex optimizer in a MATLAB project through the Cplex Class API for MATLAB. The project works fine when run in the MATLAB dev environment.

However, I am not able to complile this project with MATLAB's compiler.

Here is the message I get when I add my project's main file in the MATLAB compiler interface:

"The following error was encountered when analysing user added files. MATLAB code 'C:\Program Files\IBM\ILOG\CPLEX_Studio126\cplex\matlab\x64_win64\@Cplex\Cplex.m' contains the following syntax error(s): L 248 (C7-14): FUNCTION keyword use is invalid here. This might cause later messages about END. L1040 (C 4-6): Parse error at END: usage might be invalid MATLAB syntax."

And then nothing. No files are added and nothing gets compiled.

Any ideas? Thanks for your help.

MATLAB version: R2014a Cplex Studio version: 12.6

Hi Nicolas,

A colleague at work found the solution to this problem. Apparently some capabilities have been removed from the Matlab compiler, including support for compiling code with a classdef. Our code that calls Cplex will compile with the mcc from R2012b and run wihtout any runtime errors. It will compile with R2012a, but not run. It gets runtime error: undefined symbol:_ZN2fl4i18n14MessageCatalog18MessageCatalogInitERKSbItSt11char_traitsItESaItEE

I hope that helps,

Paul
