ERROR: Solver "CPLEX"returned with nonzero exitcode 1

[Tuong Nguyen Manh]

Hi there,

One of our user is trying to run our Gams model and encounter this ERROR

.....

--- Executing CPLEX: elapsed 0:14:41.282

*** gevCallSolver: Solver failed <CPLEX,LP,sl=5>

*** gevCallSolver: rc=1 msg=The specified module could not be found.

 <problem occured when trying to load cpicclib64.dll>

*** Failure calling solver: CPLEX <rc=1>

ERROR: Solver "CPLEX"returned with nonzero exitcode 1

--- Restarting execution

This user has Gams runtime licence and he confirm that there is cpicclib64.dll file in GAMS folder.

Can you please tell me what could be wrong here?

Thanks and best regards

Tuong Nguyen

This is odd. What operating system (what Windows version) does your user run? If could be that some other DLLs are missing (which are usually present with regular Windows versions). There is a great tool called depends (http://www.dependencywalker.com/) that shows the dependency of DLLs. Make sure you download the x64 version. When you open the cpicclib64.dll file in depends.exe it will show you if a library is missing. The tool reports some system libs to be missing but that's okay. When I run the tool on my Windows 7 x64 box I get a result as show in the attached screen shot. Let your user do the same and hopefully depends finds some DLL that is truely missing.

Sorry, I attached the screen shot for the cpxcclib64.dll not cpicclib64.dll. Here comes the correct one. Michael

Hi Michael,

Thank you for your reply. I think my user run it on window 13. Can it be an issue?

I will get my user to try it tomorrow.

Cheers

Hi Michael,

Thank you for your help. I am the user that is having the issues with CPLEX and GAMs.

See the attached screenshot of the dependency walker.

I am running GAMS 24.4 on windows 8.1 64bit.

Cheers,
Karl

Karl,

The screen-shot shows that the DLL "cplex1262.dll" cannot be found. It
should be next to cpicclib64.dll in the GAMS system folder (which is
C:\GAMS\win64\24.4 by default). Can you check if it is there? If not it
might help to do a clean installation of the GAMS system. You can get
this version of GAMS from here:

http://www.gams.com/download/download_old.htm

Best regards,
Lutz

Hi Lutz,

Thank you for your help.

Apologies for the lack in replies but after jumping through many holes in our IT system a fresh install to 24.5 has fixed this issue.

Karl
