MKL distribution problem

wilcox__nigel — Mon, 12 Aug 2019 13:50:25 GMT

I have a mixed language program that uses a fortran DLL that uses the MKL, everything works fine on the development machine but when I try to distribute it to another machine I get a module not found error when the program calls the DLL. Through a process of elimination I have tracked the problem down to the MKL. If I do not include the MKL in the link and remove all calls to MKL routines everything is fine. As soon as I add the MKL to the link, I get the module not found error even with no calls to the MKL routines. I have tried installing MKL onto the distribution machine, and adding all the redist MKL dlls to the installation folder but neither makes any difference.

I am using MKL 2019 update 4 on both machines.

Any ideas gratefully accepted.

I may have found the problem

I may have found the problem to this. If I set the MKL option to sequential rather than parallel then everything works fine. The test distribution machine is only windows 10 home and maybe cannot handle parallel processing.

I would still be grateful for any clarification on this

Thanks

A further update, it appears

A further update, it appears to be a windows 10 problem as the parallel version will not run on win 10 pro, or win 10 home.

The development machine is Win 7 and so it looks to be some issue with compiling on win 7 and distributing to win 10. I have not had a problem doing his with any other program so it appears peculiar to MKL.

Thanks
