Error during mex: "collect2: fatal error: cannot find 'ld'"

Hi,

I get an strange error on my Linux machine (Ubuntu 16.04) when trying to compile the example file arrayProduct.cpp:

>> mex arrayProduct.cpp

Building with 'g++'.

Error using mex

collect2: fatal error: cannot find 'ld'

compilation terminated.

however, the linker ld is visible from matlab... what can be going wrong?

>> !which ld

/usr/bin/ld

Any help welcome,

Daniel
