为什么无法在ABAQUS子程序中调用MKL-FFTW3库

Question

我找到了一种在https://software.intel.com/en-us/forums/intel-math-kernel-library/topic/720340的ABAQUS子程序中调用MKL库的方法。我按照下面的方法添加了

compile_fortran=[...'/Qmkl:sequential'...]

它可以和普通的MKL库很好地协同工作，比如degsv等等。但是当我想调用MKL-FFTW3库时，ABAQUS会显示错误，我会检查日志文件，错误如下

Abaqus Error: Problem during linking - Abaqus/Standard User Subroutines.
This error may be due to a mismatch in the Abaqus user subroutine arguments.
These arguments sometimes change from release to release, so user subroutines used with a previous release of Abaqus 
may need to be adjusted.

我使用了Visual Studio 2017、英特尔Visual Fortran 2019、ABAQUS 2019。

谢谢你的帮助。

所有这些FFTW3接口都集成到英特尔MKL中。它们在英特尔®64架构的mkl_intel_ilp64.lib、mkl_intel_ilp64_dll.lib mkl_intel_lp64.lib、mkl_intel_lp64_dll.lib和mkl_rt.lib中定义。

您可以尝试按照MKL Linker Adviser提示手动链接MKL。
