MinGW should be installed first.
GotoBLAS2 is an implementation of Basic Linear Algebra Subprograms (BLAS).
LAPACK uses BLAS.
GotoBLAS2 has configurations for a variety of hardware platforms. It builds a library that is optimized for the given PC’s CPU.
Make a folder called: c:\LAPACK
Download GotoBLAS2. Filename = GotoBLAS2-1.13_bsd.tar.gz
Save File to: c:\LAPACK
Then open and extract with jZip or some other utility.
jZip is available for free at:
The extracted files should appear in:
wget – is a utility that retrieves files using HTTP, HTTPS and FTP
It will be used in the “make” process to download the latest LAPACK files.
It is given in file: wget
Copy wget into c:\MinGW
Then rename it as: wget.exe
(This approach is needed to circumvent Email firewalls.)
Next… Open the Unix-like shell
Programs > MinGW > MinGW Shell
$ cd /c/LAPACK
$ mkdir include (make include sub-folder)
Install the files from: includes.tgz (This is for CBLAS).
$ cd /c/LAPACK/GotoBLAS2 (The $ sign is the prompt)
(this is the step to build the libraries for LAPACK & GotoBLAS2)
$ ls *.lib (directory)
You should then see a file such as:
The string in the middle depends on your CPU type.
$ nm libgoto2*.lib | grep dsptrd (file listing)
You should several lines such as
From within the MinGW shell:
Copy includes.tgz into /c/LAPACK/include
and run: tar -zxvf includes.tgz
Also check for
This dll can be used for compiling programs which use LAPACK subroutines in a pure Windows environment.
