Hi, im just trying to use the LAPACK AND BLAS LYBRARYs, I just solve the problem searching in this folder "C:\MinGW\bin", and found the file "libgfortran-5.dll", just make a copy and rename to "libgfortran-3.dll". Im using CODEBLOCKS with GNU fortran compiler, and WORKS. https://icl.cs.utk.edu/lapack-for-windows/lapack/index.html (WIN 10, but i work with 32bits lapack library)
