Setup-issues

[sschnug]

This looks interesting!

I tried to get test/buildCBC.sh to run, but no matter what i do, i fail!

It reads as all i need to do is to prepare the necessary libs (Just add all required libraries of your selected solver.) and then call the build-script.

I'm using Ubuntu and installed coinor-libcbc-dev and the other ones (cgl, coinutils, ...). Two different OS-setups made me try Cbc 2.8.12 and Cbc 2.9.9.

Both behave like this:

sascha@ubuntu-17:~/Downloads/lp/test$ ./buildCBC.sh 
../lp.cpp: In function ‘int lp_optimize(LinearProgram*)’:
../lp.cpp:1854:86: error: no matching function for call to ‘CbcModel::setMIPStart(int&, const char**, double*&)’
                 modelA.setMIPStart( lp->msVars, (const char**)lp->msNames, lp->msVal );
                                                                                      ^

          ^~~~~~~~~~~

What am i doing wrong?

I used the current commit d680 and this is some OS-output:

Thanks for you interest ! It requires cbctrunk, the development version of CBC. Right now cbc trunk is more stable than cbcstable since only bug fixes are in trunk :) To compile and build and install cbc from trunk in ubuntu including Lapack and Blas for an improved performance in matrix operations:

sudo apt-get install gfortran subversion gcc g++ autotools-dev automake autoconf

svn co https://projects.coin-or.org/svn/Cbc/trunk cbctrunk

cbctrunk/ThirdParty/Blas/

./get.Blas

cd ../Lapack/

./get.Lapack

cd ../..

./configure --prefix=/usr --enable-cbc-parallel --enable-gnu-packages

make -j 4

Cheers

ops, just forgot to add a sudo make install at the end

Yeah, that works now! Thanks. --prefix=/usr was what i was missing in earlier from-source attempts (besides the whole which code to use question)!
