# Revision 1.36  2012/03/22 19:45:40  soliday

# Modified so that SUNPERF can be set on the make command line.
#
# Revision 1.34  2009/12/03 17:17:45  soliday
# The fdlibm library is only needed by Windows.
#
# Revision 1.33  2009/12/02 22:32:08  soliday
# Updated the libaries that are linked in.
#
# Revision 1.32  2009/05/13 19:13:37  soliday

# Fixed some issues on WIN32
#
# Revision 1.29  2009/01/08 16:17:31  soliday
# Fixed an issue for 64 linux systems were HOST_ARCH is set to Linux.
#
# Revision 1.28  2008/08/22 15:38:28  shang
# added sddsmatrixop
#
# Revision 1.27  2008/06/03 16:15:59  soliday
# Added back CLAPACK support on Windows.
#
# Revision 1.26  2008/04/16 22:51:26  emery
# Removed -I$(CLAPACK_INCLUDE) for linux and CLAPACK flag
# since the C-lapack hearder file is no longer necessary.
# (LAPACK is compiled in gfortran for linux now.)
#
# Revision 1.25  2008/04/16 15:20:59  soliday
# Fixed issues with building CLAPACK version on Solaris.
#
# Revision 1.24  2008/04/14 18:50:50  soliday
# Fixed some changes in the Makefile.
#
# Revision 1.23  2008/04/11 21:34:19  emery
# Added comments on the use of the CLAPACK flag.
# Added comment on how the nested if statements is structured.
# Changed the libraries for CLAPACK macro set; this is due to the
# different set of libraries that the new version of ATLAS
# produces. Use pthread for CLAPACK (ATLAS).
# Added macro definitions and libs for 64-bit compilation.
# Define F77SYSLIB for CLAPACK (ATLAS).
# Added comment that meschach include file is necessary for all
# methods because of the matrix structure from meschach is adopted
# in sddspeudoinverse.c
#
# Revision 1.22  2007/07/16 16:56:10  soliday
# Updated to work on Windows computers without CLAPACK.
#
# Revision 1.21  2007/03/30 18:49:17  soliday
# Changed so that it always uses CLPACK on Windows
#
# Revision 1.20  2006/08/24 21:22:52  soliday
# Updated to work with CLAPACK on WIN32
#
# Revision 1.19  2006/02/14 20:44:33  soliday
# Modified so that -dalign is only used with the Solaris compiler.
#
# Revision 1.18  2005/12/20 16:37:30  soliday
# Changed so that the SUNPERF library is not used by default even
# if it is found.
#
# Revision 1.17  2005/11/17 17:44:52  soliday
# Accidentally made CLAPACK the default in the last change.
#
# Revision 1.16  2005/11/17 17:36:48  soliday
# Updated to work cleaner with CLAPACK libraries.
#
# Revision 1.15  2005/08/03 22:29:19  emery
# Moved choice of SUNPERF to bottom of ifdef structure to avoid
# having it selected before checking for CLAPACK or LAPACK.
#
# Revision 1.14  2005/08/01 21:37:34  emery
# This revision is not changed from 1.13; just the log
# message is changed.
# For CLAPACK and LAPACK, use USR_LIBS macro instead of
# USR_LDFLAGS and OP_SYS_LDFLAGS.
# Added many macros of the type <package>_INSTALL_DIR
# where package is one of LAPACK CLAPACK ATLAS F2C
# for use in conjunction with USR_LIBS. For example
# for USR_LIB += lapack, then a macro lapack_DIR must
# exist and its value must contain the directory
# where file lapack.a is found.
#
# Revision 1.13  2005/07/17 04:04:08  emery
# First installation.
#
# Revision 1.12  2005/07/14 18:41:48  emery
# Corrected bug where NUMERICAL_RECIPES flags was always selected.
# Added statement to set linear algebra package selection macros to zero
# if they were previously not defined.
#
# Revision 1.11  2005/07/14 17:58:13  emery
# Added MACRO flags in a commented block which allow for benchmarking various
# methods of SVD. The file as is will link to the meschach SVD by
# default in general or to SunPerf on a solaris system.
#
# Revision 1.10  2005/07/13 15:30:30  soliday
# Updated to properly link when using the sun performance library.
#
# Revision 1.9  2005/02/25 23:26:13  soliday
# Updated so that a static build on solaris will work.
#
# Revision 1.8  2005/01/21 20:30:42  soliday
# Updated to support purify on Linux
#
# Revision 1.7  2004/12/16 16:13:20  soliday
# Updated to detect GNU builds on solaris with newer version of Base.
#
# Revision 1.6  2004/09/24 17:05:10  soliday
# Updated to work on solaris machines without the sunperf library installed.
#
# Revision 1.5  2004/03/16 16:58:06  soliday
# Updated purify, quantify, and purecov build rules
#
# Revision 1.4  2003/08/28 22:37:48  soliday
# Modified so that vxWorks does not try to build this with EPICS 3.14
#
# Revision 1.3  2003/07/25 16:17:21  soliday
# Simplified makefile
#
# Revision 1.2  2003/07/23 21:43:15  soliday
# Fixed issue with Linux
#
# Revision 1.1  2003/07/23 19:58:02  soliday

# CLAPACK               free, LAPACK that uses ATLAS.
