Installing libsvm3.0 on Mac OS X (10.6.6) running MATLAB R2010b (7.11)

Hi all,

I'm running Mac OS X (Snow Leopard 10.6.6) and Matlab R2010b (7.11.0.584). I'm trying to install a package called libsvm (http://www.csie.ntu.edu.tw/~cjlin/libsvm/). I've tried running make at the terminal but I keep getting some cryptic errors and don't know how to deal with them. Below are the contents of Makefile

      ###  This Makefile is used under Linux
    #MATLABDIR ?= /usr/local/matlab
    ### for Mac
    MATLABDIR ?= /Applications/MATLAB_R2010b.app
    CXX ?= g++
    #CXX = g++-4.1
    CFLAGS = -Wall -Wconversion -O3 -fPIC -I$(MATLABDIR)/extern/include
    MEX = $(MATLABDIR)/bin/mex
    MEX_OPTION = CC\#$(CXX) CXX\#$(CXX) CFLAGS\#"$(CFLAGS)" CXXFLAGS\#"$(CFLAGS)"
    # comment the following line if you use MATLAB on 32-bit computer
    MEX_OPTION += -largeArrayDims
    MEX_EXT = $(shell $(MATLABDIR)/bin/mexext)
    OCTAVEDIR ?= /usr/include/octave
    OCTAVE_MEX = env CC=$(CXX) mkoctfile
    OCTAVE_MEX_OPTION = --mex
    OCTAVE_MEX_EXT = mex
    OCTAVE_CFLAGS = -Wall -O3 -fPIC -I$(OCTAVEDIR)
    all:  matlab
    matlab:  binary
    octave:
    @make MEX="$(OCTAVE_MEX)" MEX_OPTION="$(OCTAVE_MEX_OPTION)" \
    MEX_EXT="$(OCTAVE_MEX_EXT)" CFLAGS="$(OCTAVE_CFLAGS)" \

When I type make in the terminal, I get this error message:

/Applications/MATLAB_R2010b.app/bin/mex CC#g++ CXX#g++ CFLAGS#"-Wall -Wconversion -O3 -fPIC -I/Applications/MATLAB_R2010b.app/extern/include" CXXFLAGS#"-Wall -Wconversion -O3 -fPIC -I/Applications/MATLAB_R2010b.app/extern/include" -largeArrayDims svmpredict.c svm.o svm_model_matlab.o
ld64-62.1 failed: library not found for -lgcc_s.10.5
collect2: ld returned 1 exit status

mex: link of ' "svmpredict.mexmaci64"' failed.

make: *** http://svmpredict.mexmaci64 Error 1

I notice that it says library not found for -lgcc_s.10.5. What does this mean and how could I possibly fix it?

LIBSVM also comes with a make.m script for running it within matlab. However when I run it there a whole bunch of errors (I'm only showing the first 7) like this:

    svm.cpp:1:18: error: math.h: No such file or directory
    svm.cpp:2:19: error: stdio.h: No such file or directory
    svm.cpp:3:20: error: stdlib.h: No such file or directory
    svm.cpp:4:19: error: ctype.h: No such file or directory
    svm.cpp:5:19: error: float.h: No such file or directory
    svm.cpp:6:20: error: string.h: No such file or directory
    svm.cpp:7:20: error: stdarg.h: No such file or directory
     mex: compile of ' "svm.cpp"' failed.
    ??? Error using ==> mex at 208
    Unable to complete successfully.

You do not have g++ fully installed, or possibly not installed at all. You also do not have a C compiler fully installed.

Have you installed XCode from your Snow Leopard installation CDs? It does not install by default.

Brilliant! Installing XCode allows it to install properly. Thanks so much for the help.
