# octave/cfg - "Build" settings for package

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

[technotes]

1. Regarding the dependency list:  This package also needs "gfortran",
but that's part of the main gcc package.

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

2. "octave" uses a set of libraries known as "lapack". If the system's
version of "lapack" is used (as opposed to the version that comes with
"octave"),  the system's  version must be built a certain way,  or the
"octave" build process (and/or "octave" itself) may lock up.

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

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

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

3. "octave" 3.4.2 required "qhull" 2003.1  (neither  older  nor newer)
built  with  CFLAGS equal to  (or containing)  the following  compiler
flag:
      -fno-strict-aliasing

As of 2018,  it wasn't known whether or not this requirement was still
in effect for newer releases of "octave".
