loadlibrary does not find a function

Hello, I'm trying to load a C libary into Matlab.

The case is very simple.

The header file libwrapper.h:

void call2(int)

The C file wrapper.C

#include "libwrapper.h"
void call2(int t)
{
}

The library is built as follows:

gcc -shared ./wrapper.c  -o libwrapper.so

I checked with the nm command, the symbol call2 is in the library.

If I call in Matlab loadlibrary('libwrapper.so'), matlab does not find the function call2 (I get a warning)

What am I doing wrong?

Additional info:

I tried with an older release (2017a) and it worked well.

Now it works for me with 2019a release. I think the problem was with some environment variables of me session.

Sorry for a false alarm.

Dear Michael,

I may have the same problem, but do not know how to make it work. How did you resolved it?

Thank you very much.

Kind regards, Jan.
