Does anybody has trouble with configuring cplex (1262)  c++ concert with Visual Studio Community 2015 or visual studio professional 2015? My question is -Does cplex C++ concert technology support visual studio 2015?  All of my current cplex  project  is in visual studio 2013. 

Visual Studio 2015 is not directly supported by CPLEX yet. In order to use the Visual Studio 2015 development environment, you can use these instructions to switch it to using VS2013 compiler.

Thanks Xavier, Do you know when a version will be released that does support the VS 2015 C++ compiler?

All the best, Eddie

We plan to add support for VS2015 before the end of 2016.

I am wondering if visual Studio 2015 is now supported by CPLEX?

Hi,

VS2015 is supported by CPLEX 12.7 that was released in November 2016 as can be seen at

Hi Alex,

Thanks for the response. I have CPLEX 12.6 that I need to upgrade it to 12.7 then.

Best regards

http://www.leandro-coelho.com/how-to-configure-ms-visual-studio-to-use-ibm-cplex-concert/

 But I am getting lots of mismatches and errors.

Can anyone tell me how I should setup my project properties for this version? If you have any link that explained the configuration of this version please let me know.

Regards.

In your CPLEX installation directory you should find a readmeWindows.html file (just open that file in your browser).  From there you can link to c_cpp.html.  If you follow the instructions under "Building your own project which links with CPLEX" (exactly), you should be able to get your environment set up.  If you still have problems after that, you might want to start a new topic in the forum (this has drifted away from the original topic here).

I have applied the steps in c_cpp.html exactly for my Cplex 12.7 and Visual Studio 2015 (Community version); and I got the following error when I want to run a previously working .cpp file:

LINK : fatal error LNK1257: code generation failed

Is there something that I am missing?

@Ozgu, earlier today you had a slightly different error.  When I saw that it made me think that you might be missing ​<CONCERTDIR>\lib\x64_windows_vs2015\stat_mda in your linker section.  Did you fix that?

With regards to your new error, is it possible that you have references to x64_windows_vs2013 instead of x64_windows_vs2015?

Otherwise, I haven't had time to test anything yet, but I'll try to take a closer look tomorrow.

Also, in case you missed it, there is a related thread here.  The suggestion there, to compare your project settings with those in the example projects is a good one.

Yes Ryan, it was previously a different error; and as you guessed I was able to fix it. However I am still  stuck with this last one b/c I double checked if  "Additional Library Directories" of my Linker is correctly referring to 2015 and can conclude that  this does not seem to be the reason. Thanks for informing about the the other discussion, but I am not sure which example folder being referred in the discussion. Although the 'examples' folder inside my '..CPLEX_Studio127/cplex' folder seems to contain several VC++ project files,  source file is "C" type rather than C++ in all of them. I checked the properties of one example project for release-x64 configuration, and observed that most of them are different from the steps defined in "c_cpp.html". DO you still suggest and apply the same properties to my project?

Although, I didn't run into your exact error, I did find a few typos and omissions in the c_cpp.html file that was shipped with 12.7.  I've attached a corrected version.  Please try again with the instructions in "Building your own project which links with CPLEX".

With regards to the examples, you should find the Visual Studio 2015 C++ examples under cplex\examples\x64_windows_vs2015\stat_mda in your CPLEX 12.7 installation directory (e.g., ilolpex2.vcxproj).  One way to compare your .vcxproj project file with the example is to use a textual diff tool like WinMerge instead of trying to eyeball the differences within the Visual Studio GUI.  You can edit the .vcxproj file directly in a text editor but you have to be careful (it's best to use this technique when your project is in source code control so you can revert your changes if necessary).

@rkersh 7a1ce5ff-8650-4ae4-a67f-69adbfe5e2f6 ​Thanks for the updates Ryan, but it seems my installation have deeper issues. When I want to open a sample  .vcxproj (particularly admipex1.c was the one that I tried) from the folder you indicated, my Visual Studio 2015 exited with code 0. No solve etc. I don't know what the substantial problem about it.

I wasn't very explicit about this above (sorry about that), but the C++ examples usually all start with "ilo".  So, admipex1 is the C version of the example and iloadmipex1 is the C++ version.  It sounds like the example compiled and when you executed it, it just exited immediately with the usage statement (this happens very quickly from within the Visual Studio IDE).  You can set command line options in Visual Studio by going to Project Menu > Properties > Debugging section > Command Arguments.  For admipex1 or iloadmipex1 you need to pass in the path to a model file like mexample.mps (which can be found in the cplex\examples\data folder).  The program can still execute so quickly that you still don't see anything.  So, you either have to set a break point in Visual Studio or simply run the admipex1.exe file from the command line so you can see all of the output.

Thanks.

No, you'll need to upgrade to CPLEX 12.7 to get VS 2015 support. See the detailed system requirements here.

On the other hand, if you only want to use the VS 2015 IDE, I believe you can use it with a VS 2012 project (i.e., with the old compiler).  You should double check that, though.

https://edisciplinas.usp.br/pluginfile.php/1995427/mod_resource/content/3/c_cpp.html

 But I am getting a mistake in the last step which is "Build solution"

The error is the following :" Main.cpp
1>..\..\..\..\..\Desktop\Code_blocking_Sum_Cj_AVF\Main.cpp(1): fatal error C1083: Cannot open include file: 'ilocplex.h': No such file or directory
1>
1>Build FAILED."

Can anyone tell me how I should correct this error? If you have any link that explained the configuration of this version please let me know.

Best Regards Ines.

It seems your "Additional Include Directories" item is missing the correct directories. Please double check what you have there and post the setting of this item here if the problem persists.

In the "Additional Include Directories", I set the following directories 

C:\Program Files\IBM\ILOG\CPLEX_Studio_Community127\cplex\include

C:\Program Files\IBM\ILOG\CPLEX_Studio_Community127\concert\include

Then I suspect that in your code you wrote

#include <ilocplex.h>

while you should write

#include <ilcplex/ilocplex.h>

in your source code (take a look at the examples shipped with CPLEX, they should have the correct include directive).

 It is right in my code i wrote : #include <ilocplex.h>

I changed it to  : #include <ilcplex/ilocplex.h>

but it always the same problem in the build step there is an error : "1>LINK : fatal error LNK1181: cannot open input file 'cplex127.lib'
1>
1>Build FAILED.
1>
1>Time Elapsed 00:00:04.51

- Have you an available versiion of the Cplex 12.6.0 please?

If cplex127.lib cannot be found then you either do not have CPLEX 12.7.1 installed or your configuration of the 'Additional Library Directories' is wrong.

Note that the c_cpp.html file you pointed to is for version 12.6.2. If you installed 12.7.1 then you should find a c_cpp.html file for that version in the top-level cplex/ installation directory. Follow the instructions in that file rather than those for 12.6.2.
