error running mexa64 build from cpp file on ubunto

Hi everyone, i built a mex file from a cpp file on ubunto. it worked successfully. But when i'm running the mexa64 file, matlab craches and i get this long error msg: java.lang.UnsatisfiedLinkError: no nativeservices in java.library.path at java.lang.ClassLoader.loadLibrary(Unknown Source)....

However, i tried to run mexa64 from cc files and it works without problems.

thanks for help

apt-get install matlab-support

thanks for your reply. the mex file runs without errors,however the output of the mex function (called HoT) always give me zeros (on several images):

m=double(imread('0.png'));feature=HoT(im);
>>feature =
     0
     0
     0
     0

I tried on windows and it works correctly:

im=double(imread('0.png'));
>> feature=HoT(im);
>> feature =
    3.3285
    2.2477  
   12.9287

And i tried to run a mexa64 file built from a cc file it works correctly on both systems. Is there a difference between mexa file from cc and cpp files? I didn't knew the problem.
