在Windows上以八度方式安装liblinear

Question

i am trying to install liblinear 1.91 in octave 3.6.2 on windows 7. octave is a clean mingw install without extra packages except for libsvm 3.12. please note libsvm installed without a problem by running make.m from octave. however when i try the same for liblinear i get:

please help.

Answer 1

starting from the liblinear-1.91/matlab folder, this compiles for me:

cd ..
mex   -c linear.cpp
mex   -c tron.cpp
cd blas
mex   -c *.c
cd ../matlab
mex libsvmread.c
mex libsvmwrite.c
mex train.c linear_model_matlab.c ../linear.o ../tron.o ../blas/*.o
mex predict.c linear_model_matlab.c ../linear.o ../tron.o ../blas/*.o

Answer 2

I am using octave 3.6.2 with Visual Studio 2010.

I first followed the instructions here to get libsvm working: http://flyingpies.wordpress.com/2012/11/20/getting-libsvm-to-work-with-octave-on-windows/

To get liblinear compiled, run octave with visual studio environment variables (see link above), cd to the liblinear directory, and run these commands:

mex -c 'linear.cpp' 
mex -c 'tron.cpp' 
cd blas
mex -c 'daxpy.c' 
mex -c 'ddot.c' 
mex -c 'dnrm2.c' 
mex -c 'dscal.c'
cd ..\matlab 
mex -DMX_API_VER=0x07030000 -c linear_model_matlab.c -I..\\ 
mex -DMX_API_VER=0x07030000 train.c -I..\\ '..\tron.o' '..\linear.o' 'linear_model_matlab.o' '..\blas\daxpy.o' '..\blas\ddot.o' '..\blas\dnrm2.o' '..\blas\dscal.o' 
mex -DMX_API_VER=0x07030000 predict.c -I..\\ '..\tron.o' '..\linear.o' 'linear_model_matlab.o' '..\blas\daxpy.o' '..\blas\ddot.o' '..\blas\dnrm2.o' '..\blas\dscal.o' 
mex -DMX_API_VER=0x07030000 libsvmread.c 
mex -DMX_API_VER=0x07030000 libsvmwrite.c
