Ultimately I'm trying to install both so that I can use the LA packages (as a library) with Fortran 77 code compiled with gfortran. I'm using Maz OS X 10.6.8 and am attempting to install lapack version 3.5.0

Initially I followed the instructions given here: http://gcc.gnu.org/wiki/GfortranBuild for BLAS and LAPACK installation, but on getting some errors switched to the instructions given here: http://pheiter.wordpress.com/2012/09/04 ... on-mac-os/ and followed them exactly. To save you clicking on the link:

Both packages are required when you deal with linear algebra operations, e.g. solving linear equation systems. Originally, both packages were written in FORTRAN, but I want to use them coding in C++. The solution is to create a libraray! There’re a few steps to consider while installing the packages. First, you have to install BLAS, because LAPACK requires it. If you have downloaded both packages, unzip them. Switch to the BLAS folder and execute

$ make

to compile all fortran files. After that, execute

$ mv blas_UNIX.a libblas.a

to rename the created library. Now, you created a library called “libblas.a”. You just copy that file to your library folder. Therefore execute the following command

sudo cp libblas.a /usr/local/lib/

Et voila. You’ve installed the BLAS package. Now switch to the LAPACK folder and adjust the file “make.inc”. If you set all parameter correctly, execute the command

$ make

My BLAS directory is Users/username/BLAS, LAPACK is users/username/lapack-3.5.0

In my make.inc file

- Code: Select all
`BLASLIB = libblas.a`

Having done all that the errors in the testing that caused me to switch to the other installation instructions when I run make are still there, and I've been unable to find useful references to them on the web:

( cd INSTALL; make; ./testlsame; ./testslamch; ./testdlamch; \

./testsecond; ./testdsecnd; ./testieee; ./testversion )

make[1]: Nothing to be done for `all'.

We are about to check whether infinity arithmetic

can be trusted. If this test hangs, set

ILAENV = 0 for ISPEC = 10 in LAPACK/SRC/ilaenv.f

Infinity arithmetic performed as per the ieee spec.

However, this is not an exhaustive test and does not

guarantee that infinity arithmetic meets the ieee spec.

We are about to check whether NaN arithmetic

can be trusted. If this test hangs, set

ILAENV = 0 for ISPEC = 11 in LAPACK/SRC/ilaenv.f

NaN arithmetic performed as per the ieee spec.

However, this is not an exhaustive test and does not

guarantee that NaN arithmetic meets the ieee spec.

Parameter 1 to routine SGEMV was incorrect

Mac OS BLAS parameter error in SGEMV , parameter #0, (unavailable), is 0

Parameter 1 to routine DGEMV was incorrect

Mac OS BLAS parameter error in DGEMV , parameter #0, (unavailable), is 0

Parameter 1 to routine CGEMV was incorrect

Mac OS BLAS parameter error in CGEMV , parameter #0, (unavailable), is 0

Parameter 1 to routine ZGEMV was incorrect

So, I'm at a loss and could do with some direction. I'm not even sure if this is at all important to be honest, so any insight would be welcome.

Thanks in advance,
