kolmogorovs maxflow library

[Tim Kacprowski]

hello,

i have a problem getting kolmogorvs maxflow library (http://pub.ist.ac.at/~vnk/software.html) to work with octave on ubuntu 12.04.

i thought the simplest way would be to use the wrapper mex library available at (http://www.mathworks.de/matlabcentral/fileexchange/21310-maxflow).

i compiled it using:

mkoctfile -v --mex maxflowmex.cpp 
g++ -c -fPIC -I/usr/include/octave-3.2.4 -I/usr/include/octave-3.2.4/octave -I/usr/include/mpi -I/usr/include/freetype2 -O2 -g -I. maxflowmex.cpp -o maxflowmex.o
In file included from ../maxflow_purec/graph.h:43:0,
                 from maxflowmex.cpp:20:
../maxflow_purec/block.h: In member function ‘Type* Block<Type>::New(int)’:
../maxflow_purec/block.h:124:76: warning: deprecated conversion from string constant to ‘char*’ [-Wwrite-strings]
../maxflow_purec/block.h: In member function ‘Type* DBlock<Type>::New()’:
../maxflow_purec/block.h:223:76: warning: deprecated conversion from string constant to ‘char*’ [-Wwrite-strings]
g++ -shared -Wl,-Bsymbolic -o maxflowmex.mex maxflowmex.o -L/usr/lib/octave-3.2.4 -loctinterp -loctave -lcruft -Wl,-Bsymbolic-functions -Wl,-z,relro -llapack -lblas -lfftw3 -lfftw3f -lreadline -lncurses -ldl -lhdf5 -lz -lm -lgfortranbegin -lgfortran

this seemed to work fine. but when i want to execute the test functions in octave i get:

octave:1> test1()
error: `maxflowmex' undefined near line 35 column 18
error: called from:
error:   [...]/maxflow_mex/maxflow.m at line 35, column 16
error:   [...]/maxflow_mex/test1.m at line 32, column 16

 

i hope someone can point me to what's going wrong here.

thanks

tim
