[SciPy-user] Install issues with lapack

[Stephen Boulet]

I'm trying to install scipy, but I'm having trouble with lapack.

According to "http://math-atlas.sourceforge.net/errata.html#completelp" (as 
Pearu mentioned), I should "[f]irst, download and install the standard LAPACK 
library from the LAPACK homepage."

I copied "INSTALL/make.inc.LINUX" to "/usr/src/LAPACK/make.inc". I understand 
that not altering the file "Makefile" will give you all the types (single, 
double, complex, and complex16). From the lapack docs:

     By default, the presence of no arguments following the make command 
     will result in the build- ing of all four data types.

The file "Makefile" has this in it by default:

     all: install lib testing blas_testing timing blas_timing

     lib: lapacklib tmglib
     #lib: blaslib lapacklib tmglib

Just typing make, though, leads to this error after some compilation:

     g77: ../../blas_LINUX.a: No such file or directory

The compile did put the files "tmglib_LINUX.a" and "lapack_LINUX.a" in 
"/usr/src/LAPACK".

Where does blas_LINUX.a come from? Lapack's install instructions say:

   Next, if you will be using a locally available BLAS library, you 
   will need to remove blaslib from the lib definition.
