About two months ago, I successfully installed Abaqus 2023, Visual Studio, and the Intel oneAPI Base/HPC Toolkits, and after following the suggestions in a previous community question (New issues running user subroutines with Abaqus 2023) to modify the abaqus_v6.env file, all of the abaqus verification tests passed and I was able to use user subroutines.

As of about a week ago, this changed where subroutines will compile, but I now am receiving a linking error (as indicated from the std_user.log file):

"LINK : fatal error LNK1104: cannot open file 'mkl_intel_lp64.lib'

Has anyone else experienced this?/ Do you know how I can 1. get this file and 2. link this file to abaqus? I just find it very odd that this same system would work and then stop.

As an extra bit of information on things I have looked into, I am also seeing the following remark (not error) during compilation:

"ifort: remark #10448: Intel(R) Fortran Compiler Classic (ifort) is now deprecated and will be discontinued late 2024.  Intel recommends that customers transition now to using the LLVM-based Intel(R) Fortran Compiler (ifx) for continued Windows* and Linux* support..."

The compilation still completes successfully, but just to check, I modified the win86_64.env file to use the "ifx" compiler instead and the remark went away, compilation was still successful, but still got the same linking error as before with the "ifort" compiler. So I don't think it is the compiler that is the issue, but would the deprecated "ifort" compiler also change the mkl installation somehow? I'm not sure how to even check that.

Any help/ideas would be greatly appreciated.
