Hi everyone,
I am trying to create a mex file so that I can call opensim functions from MatLab. My test.cpp file is as below:
Code: Select all
#include "mex.h"
#include <OpenSim/OpenSim.h>
using namespace OpenSim;
using namespace SimTK;
void mexFunction( int nlhs, mxArray *plhs[],
int nrhs, const mxArray *prhs[] )
{
// Calculations
}
I have changed the
mexopts.bat file and included these two additional directories:
- C:\OpenSim2.4.0\sdk\include\SimTK\include
- C:\OpenSim2.4.0\sdk\include;
When I type
mex test.cpp in MatLab command line, it returns these errors:
test.cpp
c:\opensim2.4.0\sdk\include\opensim\common\PropertySet.h(124) : warning C4290: C++ exception specification ignored except to indicate a function is not __declspec(nothrow)
c:\opensim2.4.0\sdk\include\opensim\common\PropertySet.h(128) : warning C4290: C++ exception specification ignored except to indicate a function is not __declspec(nothrow)

C:\PROGRA~1\MATLAB\R2010A\BIN\MEX.PL: Error: Compile of 'test.cpp' failed.
??? Error using ==> mex at 222
Unable to complete successfully.
Error in ==> testMex at 8
mex test.cpp
Any ideas how can I solve the problem?
Thanks
Sina
p.s: I have attached the modified mexopts.bat file.

Sina,
I'm not sure if this will help you but I'm attaching an example Matlab command which I use to compile a mex file for my OpenSim application. Perhaps you can adapt it to match your needs.
First cpp file is contains mex function. Other cpp files contains other needed code.
-L indicate library locations
-l indicate libraries themselves
-I indicate include folders
-D indicate preprocessor definitions
Code: Select all
mex SurrogatePluginMex.cpp ANN_TFContactForce.cpp ANN_PFContactForce.cpp...
-L'C:\OpenSim 3.1\sdk\lib'...
-L'C:\Users\eskilan\Documents\testing embbeded coder\Multiset models JW\PF\PFsurrDLL\Release'...
-L'C:\Users\eskilan\Documents\testing embbeded coder\Multiset models JW\TF (correct insert)\TFsurrDLL\Release'...
-losimCommon -losimSimulation...
-losimAnalyses -losimActuators -losimTools...
-lOpenSim_SimTKcommon -lOpenSim_SimTKmath...
-lOpenSim_SimTKsimbody -lSimTKlapack -lpthreadVC2...
-lTFsurrDLL -lPFsurrDLL...

Thank you Ilan, it is working now!
