# lapack/cfg - "Build" settings for package

#---------------------------------------------------------------------

[technotes]

1. The source tarball used by this package has been renamed.

#---------------------------------------------------------------------

2. "lapack" should be built a certain way  or it may lock up.  The re-
quirement is explained below  (and this package makes a related change
to address the issue).

The required  "lapack" change  is as follows:  In the  "make.inc" file
that's used to build "lapack",  the parameters OPT and NOOPT should be
set as shown below:

    OPTS  = -mieee-fp -ffloat-store -fPIC -O2
    NOOPT = -mieee-fp -ffloat-store -fPIC
