error of addind the SCIP dll to a C# Google or-tools exmaple project

[usac...@gmail.com]

Hi,

I need to call SCiP to solve MINLP models in C# in VS 2013 on win7.

I have downloaded and installed or-tools and also downloaded SCIP library ( Windows/PC, 64bit, msvc 12.0 ) from
http://scip.zib.de/#download

When I tried to add the dll to a C# project of or-tools exmaple, I got error:

   please make sure that the file is accessible and that it is valid assembly or component.

Any help would be appreciated.

Thanks

[Laurent Perron]

I cannot distribute or-tools with SCIP for licences reasons.
You will need go build it trop the sources.

The instructions are on the développer page.

Thanks

Hi,

I have added  SCIP ( downloaded from http://scip.zib.de/download.php?fname=scipoptsuite-3.1.1.tgz) to google or-tools

folder "or-tools-master\dependencies\archives".

I am trying to build or-tools source code on win 7 by following the instructions at:

https://developers.google.com/optimization/docs/installing#source_windows

When I ran "nmake third_party", i got error:

      makefile(23): fatal U1034 L syntax error: seperator missing

I do not have "make" in visual studio 12.0 /bin folder. I only have "nmake".

How to build or-tools for my visual studio on win 7 ?

Any help would be appreciated.

Run tools\make third_party.
It should be in the installation documentation.

Hi,

I have checked the install document and do not find a solution.

I have installed git (Git-1.9.5-preview20150319.exe) from http://git-scm.com/download/win

and when I built or-tools by running "make.exe third_party", got error:

  sh: C:\program: no such file or directory.

  fatal : not a git repository (or nay of the parent directories):  .git

I also tried to build it in cygwin and got error:

   $ tools/make.exe third_party
    fatal: Not a git repository (or any of the parent directories): .git

Hi,

But, I got a new error:

Hi,

I found a problem of bullding the or-tools.

In cygwin, when I ran

      tools/make.exe third_party

in or-tools-master\makefiles , the makefile

     Makefile.third_party.unix

was run. Not Makefile.third_party.win


In VS2013 X64 Native tools command promot, when I ran

      tools/make.exe third_party

also the makefile that was run is

        Makefile.third_party.unix

Why ?

I need to call or-tools from VS 2013 C# on win7 not on unix.

[Laurent Perron]

Use vs2013 cross compiler please.
Cygwin is not supported, and the native compiler does not work.

Thanks

[usa usa]

Hi,

I have switched to

    VS2013 x64 Cross Tools Command Prompt

Is this VS2013 cross-compiler ?

But, got the same error.

I have added git and cmake in PATH.

the csc compiler is

   C# compiler version 12.0.21005.1

   for C# 5

Any help would be appreciated.

Hi,

I  used full path of cmake to replace CMAKE in Makefile.third_party.unix.

In VS2013 x64 cross tools command promot, I ran

      tools/make.exe third_party  

and it can build now and generate configure files in

     dependencies\sources\gflags-2.1.1

But, in the Makefile.third_party.unix

     https://github.com/google/or-tools/blob/master/makefiles/Makefile.third_party.unix

 I got new error:

    line 238:   make -j 4 && \

    lline 239 : make install

    C:\users\mypath\Temp\make112084.sh: line 1 : make command not found.

I replace make with tools/make.exe but got error:

    no targets specified and no makefile found. Stop.

Any help would be appreciated.

Thanks !

You are on windows, using makefile.unix is an error. You are likely using cygwin which is not supported. You can type make printport. It should report windows.

Hi,

I am working in the

It should be VS cross compiler. 

I ran the command:

This is the output :

I am wondering why it is unix not windows.

Hi,

The windows version is :

Why the

I am working in

Any help would be appreciated.

The documentation at https://developers.google.com/optimization/docs/installing says that the command is: 

make third_party 

There is no dash.

Hi,

At https://github.com/google/or-tools, I downloaded

   https://github.com/google/or-tools/archive/master.zip

in or-tools-master/ folder there is no make.exe.

in tools/ folder, there is make.exe.

   make.exe      working swig fix on windows

at https://github.com/google/or-tools/tree/master/tools

So, I used it to do the building.

Did I download a wrong zip file ?

[Bruno De Backer]

I meant:

 tools\make.exe third_party 

without a dash before third_party.

Hi,

Sorry, It is a typo.

This is what I have ran:

This is not the correct environment.
Do you have a visual studio 2013 64 bit cross compiler in visual studio 2013/tools menu?

--Laurent

PS: I am far from a computer.

[usa usa]

Hi,

No, I do not have this in my VS 2103/tools menu.

May I set it up in "external tools" in the same menu ?

For example,

   %comspec% /k ""C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\vcvarsall.bat""  x64

Does this can give me a 64 bit cross compiler ?

Any help would be appreciated.

Thanks

Also,

in C:\Program Files (x86)\Microsoft Visual Studio 12.0\Common7\Tools\Shortcuts

I have  Developer Command Prompt for VS2013.

Is this the cross compiler ?

This can be launched by :

      start --> all programs --> visual studio 2013 --> visual studio tools

  

I have tried it before, but it does not work.

Any help would be appreciated.

Hi,

Now, I can  run
     $ make third_party

without error.

And, I have also installed jdk at
     C:\\Program Files\\Java\\jdk1.7.0_79

I have updated makefile.local   
 
    WINDOWS_JDK_DIR = C:\\Program Files\\Java\\jdk1.7.0_79
    WINDOWS_PYTHON_VERSION = 27
    WINDOWS_PYTHON_PATH = C:\\Python27

Afterwards, to use python, I installed google-apputils:

  copy dependencies\install\bin\protoc.exe   dependencies\sources\protobuf\src
  cd dependencies/sources/google-apputils
  c:\python27\python.exe setup.py install
  cd dependencies/sources/protobuf/python
  c:\python27\python.exe setup.py build
  c:\python27\python.exe setup.py install

Now, I am trying to Compile libraries. I do not need java lib and examples. So, I changed :

    all: cc python csharp

Then I ran tools\make.exe all, I got error:

Did you use the correct arch for the python archive (32 bit or 64 bit)?

Basically, you are not finding any python module, which is strange.

BTW, just run 'make python' instead of modifying the makefile :-)

No, you don't need to.

Normally, if you run make third_party with the SCIP archive in dependencies/archives, then the library should be included.

The only thing that should be checked is if WINDOWS_SCIP_DIR is correctly set in Makefile.local.

If it is done, then make clean, make all should recompile everything with SCIP support.

Hi,

I have set  up

WINDOWS_SCIP_DIR = E:\\or-tools-master\\dependencies\\install

then I ran,

      tools\make.exe clean
      tools\make.exe all

I do not see any compile errors.

I have open the C# solution at

E:\or-tools-master\examples\csharp\solution\CSharp Examples.sln

Then I created a new C# project in the solution and I added Google.OrTools as a reference lib.

But, I cannot find the functions that should be available in SCIP.

Otherwise, how can I know that API functions that SCIP provide so that i can use them to solve models ?

   e.g.    scip.solve ( my_model) //  where is scip.solve or something like that ?

Any help would be appreciated.

thanks

[Mark]

You don't use SCIP directly, you use the ORTools linear programming API and choose SCIP as the backend solver.

For example, to use CBC as the solver I would use the line:

Solver solver__1 = new Solver("My Problem Name", Solver.CBC_MIXED_INTEGER_PROGRAMMING);

If you have SCIP installed correctly, there will be an equivalent value for SCIP.

If you want to pass specific arguments to the SCIP solver, there is a method that allows you to pass the argument name and its value (as strings I believe).  I think it was called solver_specific_params or something like that.

I'm just going off of memory.  I know I ran into issues trying to use that method from C# as well, but that was a few months ago and there may now be additional support for it.
