MATLAB: Difficulties making wrapper mex file on linux

Question

Hi,

First I complied the fcnsuit.c file as follows in a linux terminal:

gcc -c -fPIE fcnsuite.c ld -o fcnsuite.so -shared fcnsuite.o

Then I open matlab and try to make a mex file as follows:

mex mlbsuite.c

Then I get following error message:

mlbsuite.o:In function 'mexFunction':

mlbsuite.c:(.text+0xae): undefined reference to 'dlopen'

mlbsuite.c:(.text+0xd6): undefined reference to 'dlsym'

mlbsuite.c:(.text+0x217): undefined reference to 'dlclose'

          mex: link of ' "mlbsuit.mex64"' failed

How can I fix this?

Answer 1

Looks like you might need to add a

#include <dlfcn.h>

to mlbsuite.c?
