Can someone help me?

[Geoff Hayes]

Ma - it may be more useful to attach the C (or C++ or Fortran?) code that you have compiled as a mex file, and include how you are calling this function from the Command Window. That way, someone will be able to look at the code, perhaps reproduce the error that you are experiencing, and then offer some guidance on where it is going wrong.

[Ma]

Hey Geoff, thanks for your advice. I try to run the matleap.cpp from Matleap by jeffsp. The compiler had problems with the libstdc++.so.6 so I relinked it to the compiler libstdc++.so.6 as it is described here. Now it crashes after running.

[Geoff Hayes]

What are your inputs to this function?

Answer 1

[Shrirang]

Hi Ma, I have faced this "Segmentation Violation Error" while compiling C/C++ code. Following are two major causes which I found while solving the issue which might help to you. 1) A pointer variable is used without defining its size 2) And in your code you are accessing a hard coded memory location which is protected or your compiler cannot access this memory location.

[Ma]

Hey Shrirang, thank you for your help. I don't think that it is a problem with the size, because the code ( matleap code ) has been verified on other systems. Am I right?
