Error compiling mex file ubuntu with armadillo library

Hi!
I am trying to compile a mex file on ubuntu starting from a cpp file using the armadillo library. However, I get this strange error when joining 3 vectors and when determining if a vertor is full of zeros.
Error using mex
/home/b8054452/Downloads/Copy_of_MEX_EXAMPLE_2/arma_test2.cpp: In function ‘void mexFunction(int, mxArray**, int,
const mxArray**)’:

if(vec1.is_zero()==true)
^~~~~~~
The strange thing is that when compiling it with windows everything works as supposed.
Any idea how to fix it?
THANKS!
