Invalid ELF Header?

I'm trying to run a simulation that contains an S-function (originally created in C) and I keep getting the error "Invalid MEX file......Invalid ELF header". Can anyone tell me what I might be doing wrong? I had no issues when I was running this in Windows and I'm not sure why Linux keeps returning this error. I don't know much about ELF headers and I would really appreciate it if someone could explain to me what I am doing wrong here.

The S function needs to be recompiled for Linux .

I tried doing this and I still got an error message. I tried to compile it from a .cpp file (which I tried to convert to .c file so I could compile it in Linux).

[Walter Roberson]

I didn't think anyone still maintained a C++ to C translator.

gcc should be quite capable of compiling C++ code on Linux, provided that the code does not rely on MS Windows constructs.

[Stacey]

How do I use gcc to compile?

The code only relies on a .cpp file and a couple of header files.

When you do mex -setup on Linux, gcc/g++ is the only option for C++

[Stacey]

Got it. So I typed in "mex -setup C++" and then ran "mex MEXIrradition.cpp" I got this error message:

Building with 'g++'. Error using mex cc1plus: error: unrecognized command line option "-std=c++11"

I'm not sure what that means.

So I searched that error and found that it's probably because gcc is out of date. The machine I'm using has version 4.4.7. Not sure if there's any way around that.

[Walter Roberson]

You might be able to add one of -ansi, -std=c++98, or -std=c++03 between the "mex" and the filename. g++ usually pays attention to the last occurrence of an argument.

There is probably a make file that can be edited or perhaps an XML file used by mex -setup -- it would depend which MATLAB version you are using.

[Stacey]

Adding those between "mex" and the filename didn't work. I'm not sure where I can find the XML file used by mex -setup and I'm not sure if I would have permission to modify the file since I'm not the admin. I just contacted the admin for the machine to see if we can update gcc. I think that's the easiest thing to do.
