Ok, I have been able to install Dip-0.9.8 correctly, I think:
dhcp-10-231-192-228:Documents romainmontagne$ cd ./Dip-0.9.8
dhcp-10-231-192-228:Dip-0.9.8 romainmontagne$ ls
AUTHORS Data Makefile.am config.guess ltmain.sh
Alps Dependencies Makefile.in config.sub missing
BuildTools Dip Osi configure share
Cbc GiMPy README configure.ac
Cgl GrUMPy ThirdParty depcomp
Clp INSTALL build doxydoc
CoinUtils LICENSE conf install-sh
dhcp-10-231-192-228:Dip-0.9.8 romainmontagne$ cd build
dhcp-10-231-192-228:build romainmontagne$ ls
Alps GiMPy config.status
Cbc GrUMPy include
Cgl Makefile lib
Clp Osi libtool
CoinUtils bin share
Data coin_subdirs.txt
Dip config.log
However, in my "build folder", there is no "setup.py", which makes it impossible to execute the last command (COIN_INSTALL_DIR=/path/to/Dip-0.9.8/build python setup.py install )…stuck again.
There is however a setup.py in this folder:
dhcp-10-231-192-228:Dip romainmontagne$ cd /Users/romainmontagne/Documents/Dip-0.9.8/Dip
dhcp-10-231-192-228:Dip romainmontagne$ ls

README depcomp scripts

build examples test
coinor.dippy.egg-info ez_setup.py
But if i type COIN_INSTALL_DIR=/Users/romainmontagne/Documents/Dip-0.9.8/Dip python setup.py install, here is what I get:
dhcp-10-231-192-228:Dip romainmontagne$ COIN_INSTALL_DIR=/Users/romainmontagne/Documents/Dip-0.9.8/Dip python setup.py install
Traceback (most recent call last):
File "setup.py", line 87, in <module>
libraries = get_libs(coin_install_dir)
File "setup.py", line 31, in get_libs
'doc', 'Dip', 'dip_addlibs.txt')) as f:
IOError: [Errno 2] No such file or directory: '/Users/romainmontagne/Documents/Dip-0.9.8/Dip/share/coin/doc/Dip/dip_addlibs.txt'
I have a feeling I'm pretty close…I hope!

> The problem now is that when the binaries you downloaded were built, they were linked with the gfortran library. You can fix this by installing gfortran with homebrew or by removing the dependency from the dip_addlibs.txt file. However, I do believe that easiest thing is always just to download and build COIN on your own machine so that you know everything works fine. Something like the following should work:

> To answer your questions, most Python packages can be built with "python setup.py install", but they may depend on libraries that one also has to install separately and that is the crux of the problem. They Python extension that is required to use DipPy will be built automatically on all platforms with just the Python setup command, but Dip itself must already be installed somewhere.

I don't believe there could be an incompatibility with a particular flavor of Linux if you are building from source. With binaries you may not have compatibility because of the version of libc installed or something like that. But in general, I've never met a Linux machine that Dip wouldn't build and install on out of the box.

Somehow, you are ending up with a source distribution---this is either because you are using pip or because there is no binary matching your version of Python. In either case, the solution is to install Dip somewhere then set the environment variable COIN_INSTALL_DIR to the location of the installation. To install COIN, you can either download a binary distribution for OSX from here:

Then, you solve the Master Problem one last time, but this time with Integrity constraints. However it is not guaranteed that, at this point, solving the Master Problem with Integrity constraints will give you the optimal solution. Let me clarify my point with a trivial example:

However, solving the Master Problem with the integrity constraints gives an objective equal to 2 (two big rolls are cut, one of P1, the other of P2).
