Call Intel MKL as external library

I wrote a script to test a call to Intel MKL a external library but it doesn’t work. The concept: Solve a linear system using MKL “dgetrs” (Documentation Library) # Test MKL solve linear systems N = 10; A = rand(N,N); AA = copy(A); b = rand(N,1); c = copy(b); function juliaSol(A,b) \(A,b); end sol = sol = juliaSol(A,b); #Solution of the linear system # Test MKL const global librt = Libdl.find_library(["libmkl_rt"], ["/opt/intel/mkl/lib"]) # Open librt Libdl.dlopen(librt) # 101 = LAPAC…

one can assume, that between your tested releases LU factorisation somehow has a problem. The above mentioned discourse article from @Tecnezio references into the Intel documentation:
