How to use LAPACK and BLASE libraries in code::blocks?

Question

My IDE is: Code::Blocks 20.03 ( compiler: mingw 9.2.0 ) My OS is: Windows 10 Home 2004 x64

I intend to use LAPACK and BLASE libraries with gfortran programs.

I followed the instructions from the site: icl.cs.utk.edu/lapack-for-windows/lapack/index.html#libraries

Section: Build Instructions to create LAPACK and LAPACKE 3.5.0 dlls for Windows with MinGW.

I used CMake according to the steps listed in the link I posted. I had no problems during the process itself. The contents of the directory named lib after completion are:

Lapack_lib_content

I try to find out on the internet and I follow the instruction from this question:

stackoverflow?question

I also read the instructions from the code :: blocks manual( including libraries, LibFinder...)...

After build and run I got this message:

build_error

Is there a way to use the specified libraries in the specified IDE because I need them to solve certain problems from fitting data with a polynomial of a certain degree ( I do not have a money to use Intel MKL)?

Your title says `liblapack.dll` Your text says `liblapack.dll.a` Which **exact** files do you have? You did not answer that even in the discussion under your older question https://stackoverflow.com/questions/62288851/how-to-use-functions-from-lapack-and-blase-library-in-gfortran I suggested to download the dill file from your link and you replied that you have it already. However, in your text you only mention liblapack.dll.**a** . — Vladimir F Героям слава, Jun 10 '20 at 19:06
@VladimirF I made a change in the question itself. I did what you suggested to me but the result is the same. — Harry Kastorp, Jun 11 '20 at 11:47
What exactly did you write into the "Link libraries" dialog box? — Vladimir F Героям слава, Jun 11 '20 at 12:02
BTW, this is the reason I avoid IDEs. It is so much easier to use the compiler in the command line. — Vladimir F Героям слава, Jun 11 '20 at 12:02
@VladimirF Sometimes avoiding a problem is the only solution to that problem but in this case I have no choice but to learn how to find a solution if there is one at all. — Harry Kastorp, Jun 11 '20 at 12:17

The following needs to be done.

step - follow the instructions from mentioned site in question ( downloading Lapack 3.9.0, creating bin and lib directories with CMake, cmd ...)
step - right click on project => build options => linker settings and adding all files from lib directory, adding the path to lib in search directories tab..
step - it is necessary to copy all .dll files from Lapack bin to project bin\debug ( .exe file is in bin )

After performing all the listed steps, it is possible to use certain procedures from the Lapack library in code::blocks projects ( gfortran )!
