<p>Hello,</p>
<p>I have been trying to build MLPACK w/ Matlab bindings. I did the usual steps as shown below to build MEX files. But, I've been constantly facing a compilation problem that I couldn't understand. There seems some sort of problem calling the right libmlpack.so.</p>
<p>So, I commented out following codes from src/mlapack/CMakeLists.txt</p>
<p>set_target_properties(mlpack<br>
PROPERTIES<br>
VERSION 1.0<br>
SOVERSION 1<br>
)</p>
<p>The first cmake step went well without complaints.</p>

CMake Warning at CMakeLists.txt:88 (message):<br>
This is a 64-bit system, but Armadillo was compiled without 64-bit index<br>
support. Consider recompiling Armadillo with ARMA_64BIT_WORD to enable<br>
64-bit indices (large matrix support). MLPACK will still work without<br>
ARMA_64BIT_WORD defined, but will not scale to matrices with more than 4<br>
billion elements.</p>
