You may need to specify additional options to the configure script, see the platform specific instructions below.
Note that if you don't want to compile with debugging information, you can specify the `CFLAGS` and `CXXFLAGS` variables to configure, such as:
Note that if you don't want to compile the C/C++ programs with debugging information, you can specify the `CFLAGS` and `CXXFLAGS` variables to the configure script, such as:
```
./configure CFLAGS="-O3" CXXFLAGS="-O3"
```
To remove debugging information for Matlab mex functions, the analagous call would be:
```
./configure MATLAB_MEX_CFLAGS="-O3" MATLAB_MEX_CXXFLAGS="-O3"
```
If you want to give a try to the parallelized versions of some mex files (`A_times_B_kronecker_C` and `sparse_hessian_times_B_kronecker_C` used to get the reduced form of the second order approximation of the model) you can add the `--enable-openmp` flag, for instance:
```
./configure --with-matlab=/usr/local/matlab78 MATLAB_VERSION=7.8 --enable-openmp
