Build error using emlmex

This is the first time I try to convert a .m file into an executable c file. My platform is linux (ubuntu) and I am using the function emlmex.

First I start with ">>mex - setup" and I have chosen the following compiler:

 /home/user/mlab/bin/gccopts.sh : Template Options file for building gcc MEX-files

Next I defined a simple function:

function r = emcrand() %#eml
% The directive %#eml declares the function
%  to be Embedded MATLAB compliant
r = rand();

finally, I perform ">>emlmex emcrand" and I get the following:

??? Build error: Compilation returned error status code 2. See the target build log for further details.
Error in ==> emcrand Line: 1 Column: 1
C-MEX generation failed: Open error report.
??? Error using ==> emlmex

The note refers me to a target build log that has not been generated.

Note: I am using MATLAB 7.10.0 (R2010a)

My problem is not resolved yet. Any help is appreciated

Mariam: Could try:

function r = emcrand() %#eml

% The directive %#eml declares the function

% to be Embedded MATLAB compliant

r = 1; %pre-allocate to indicate type and size of r

r = rand();

And see if the error goes away?

I also have an almost the same problem. I am using Matlab 2009b on a mac. Does anyone know any possible solutions?

Eve: Please post a new question and clarify the exact error message and preferably post a simplied version of your code that can be used to reproduce the error.
