Python archive available for Windows

By -
Hello,

I have updated my scripts to create packaged binary archives.
They currently work only on windows because installing shared libraries is a nightmare on mac and linux. On windows, everything is compiled statically, and I only need to deliver one dll for 1 language on one platform. Which is nice and useful because, on the other hand, vin isual studio 2010 is not free on windows (I know about the express version).

Back to this blog post.

I have created python (new), java, and .NET archives from the latest svn on windows 32 and 64 bit. You will find them the usual place.

Thanks

    For Linux, there's http://www.pgbovine.net/cde.html , which is essentially a way to automatically copy all the needed .so/.a files to local folder. Incidentally, the creator works at Google

    Thanks :-) I will have a look.

    The real nightmare is with Mac as the path of the library is encoded at creation time.
    I have seen the otool and such utilities. Still, this seems very complicated. I still do not understand what is a Bundle, a Framework. What should I use? How?

    Hello,
    It seems python package build 2117 (google.OrTools.python.Win32.2117.zip)
    Seems to not have libraries or any setup file...
    in short it does not work.

    thanks.

    That is a harsh comment :-) I do not know how to build a setup file with native libraries.
    The libraries are in src/gen/*.

    The uncompressed archive mimics or-tools after compilation.
    It contains 3 directories: src/, examples/python and data/.

    Following the instructions in the getting started, on windows, to run an example in examples/python:

    ----------------

    For the python examples, as we have not installed the constraint_solver module, we need to use the following command:

    on windows: set PYTHONPATH=%PYTHONPATH%;\src, then c:\Python27\python.exe example\python\sample.py.

    -----------------------

    I hope this helps.

    PS: I would love some help in writing the setuptools script.

Linking glpk with or-tools on unix

By -
Following the change on SCIP, here is the new procedure to compile and link GLPK with or-tools This currently applies to unix only: First download the latest glpk archive (4.61 at the time of this post). Untar, cd into the glpk directory on linux:   ./configure --prefix=<install_path> --with-pic   make   make install on mac OS X:   ./configure --prefix=<install_path>   make CFLAGS='--mmacosx-version-min=10.8'   make install   then add:   UNIX_GLPK_DIR=<install_path> in or-tools/Makefile.local recompile or-tools:   make clean   make cc test it:   run bin/integer_programming and bin/linear_programming. Both must display glpk runs. I have no easy solution for glpk on windows currently, still investigating.

Changing the way we link with SCIP

By -
As of today, I pushed support for scip 4.0.0 on both unix and windows. In the process, I have changed the way to setup or-tools to include scip at compilation time. on Unix:   untar the scipoptsuite> archive somewhere   cd <path to scipoptsuite-4.0.0>   Mac OS X:  make GMP=false READLINE=false TPI=tny   Linux:  make GMP=false READLINE=false TPI=tny USRCFLAGS=-fPIC USRCXXFLAGS=-fPIC USRCPPFLAGS=-fPIC   in or-tools, edit Makefile.local   add:     UNIX_SCIP_DIR=<path to sciptopsuite-4.0.0>/scip-4.0.0   make clean   make cc   to test it, run:      bin/integer_programming   it should display the scip solver run. on windows:   download the compiled library:     http://scip.zib.de/download.php?fname=scip-4.0.0.win.x86_64.vc14.opt.spx2.lib.zip   download the headers:      http://scip.zib.de/download/release/scipoptheaders-4.0.0.tgz   uncompress, untar everything.   create a directory that will contains what is needed   md scip-4.0.0

Heads up, upcoming incompatibility in the CP/Routing library

By -
Hello all, I will soon push a large incompatible change in the CP and Routing libraries. The change will replace parameters (CP solver parameters, routing model parameters, routing search parameters) from struct to protobuf. This will also hide the C++ command line flags (cp_trace_search, routing_first_solution, ...) and make them redundant for controlling the behavior of the libraries. They are currently kept in the C++ library, but will be dropped out eventually. With this move, all functionalities offered by the C++ command line flags will be available from all languages (provided you implement the command line parsing part). Let's see an example (tsp) Before (in C++):    // Setting first solution heuristic (cheapest addition).    FLAGS_routing_first_solution = "PathCheapestArc";    const Assignment* solution = routing.Solve() ; After (in C++, using the command line flags compatibility) :    RoutingSearchParameters parameters =  BuildSearchParametersFro
