Issue when compile

[zizhaozhang]

Hi, I tried to compile your code using Ubuntu 14.04 with matlab 2014b I got mistakes: g++ solver_3_0.o linpack.o timer.o blas.o matlabexception.o matlabscalar.o matlabstring.o matlabmatrix.o arrayofmatrices.o program.o matlabprogram.o lbfgsb.o -shared -o lbfgsb.mexa64 -L/usr/local/MATLAB/R2014b/bin/glnxa64 -lgfortran -lm /usr/bin/ld: i386 architecture of input file solver_3_0.o' is

Do you have any idea how to solve that?
