Hi Rosen,
I am working with a 7-DoF manipulator and I am a beginner with openrave. I generated the manipulator's ik.cpp file and I used the solver with ROS/Moveit/rviz just to check that everything is ok. But that's not my main objetive.
What I really want to do is use this inverse kinematics solver in a Simulink Real Time Workshop. In a try of doing this, I want to compile my ik.cpp in a mex file in such a way I could use it as a standalone application or a standalone matlab function.
First question: Is that or something similar possible?
I am using Matlab 2014a on ubuntu trusty 64bits and openrave 0.9.
So here is my attemp:
1. After setting up gcc and g++ compilers for this version of Matlab on trusty (trusty uses by default gcc-4.8, but Matlab2014a only supports gcc/g++<4.7.x) I put ikfast.h at the same folder.
2. Then I add #include "mex.h" to both *.cpp and *.h files.
3. And I compile using mex and linking lapack and blas libraries:
mex ik.cpp -L../lib/lapack -llapack -L../lib/BLAS -lblas
Building with 'g++'.
MEX completed successfully.
4. I obtain a ik.mex64 file. "Cool", I thought. Then I have tried test this function in a similar way I could do on a linux terminal (./ik r00 r01 r02 t0 r10 r11 r12 t1 r20 r21 r22 t2 free0 ...), that is, something like this:
ik(r00, r01, r02, t0, r10, r11, r12, t1, r20, r21, r22, t2, free0)
And finally here is it my awesome matlab error:
ik(0.9721, -0.1918, -0.1347, -0.0355, 0.1844, 0.9806, -0.0659, -0.0537, 0.1447, 0.0393, 0.9887, 0.7011, 0.122)
Mex file entry point is missing. Please check the (case-sensitive)
spelling of mexFunction (for C MEX-files), or the (case-insensitive)
spelling of MEXFUNCTION (for FORTRAN MEX-files).
Invalid MEX-file '/home/ivan/Matlab_IKfast/ik.mexa64'
Second question: I'm just being silly?
Thanks in advance for any help! And congratulations for your great job.
