David Gleich's Notebook

Johan Lofberg wrote a nice function to interface the Clp linear program solver from the CoinOR project with Matlab. He distributes a precompiled version of the Clp Matlab wrapper for windows, but doesn't include one for linux. Nor are there any directions on how to compile here. I managed to get it to compile with Clp-1.9.0. My directions follow.  Issue these commands

# Download Clp-1.9.0.tgz
wget http://www.coin-or.org/download/source/Clp/Clp-1.9.0.tgz

# untar

tar xzvf Clp-1.9.0.tgz

# configure and make

cd Clp-1.9.0

./configure

make

make install

# get mexclp

wget http://control.ee.ethz.ch/~joloef/mexclp.zip

unzip mexclp.zip

# compile in matlab

matlab -nojvm -nodesktop -nodisplay 

ldf=['LDFLAGS="\$LDFLAGS -Wl,--rpath -Wl,' pwd '/lib"'];

mex(ldf,'-Iinclude/coin', '-Llib', '-lClp',  '-lCoinUtils', 'mexclp.cpp')

After compiling (hopefully successfully!)

>> clp([],[1 2 1],[1 1 1],-1,[],[])

ans = 

    0

   -1

    0

For Matlab 2008b on Ubuntu 8.10, I found it necessary to install g++-4.1, setup mex with g++-4.1 and run

./configure CXX=g++-4.1
make
make install

before everything would work.
