Hello Everyone,

I have a System Configured with P4 1.8GHz, 256 DDR RAM, 80 GB HDD PATA
which has FC10 with the default kernel 2.6.27 installed.

I have Installed following from source / tar.gz / gz files in /opt/<software>

I Installed Python 2.6.2, LAPACK-3.2.1, XBLAS-1.0.248, ATLAS-3.9.14 (
Linux_P4ESSE2 ), FFTW-3.2.2, nose-0.11.1,

Stuck at NumPy-1.3.0rc2 and will install Scipy next. I created various
Log file duing the process of './configure' or 'make'

Attached is a file with various parameters given during installation.

my lapack_LINUX.a = liblapack.a = 15MB

( I have already spent 3 weeks, to this point.... desperatly need some
guidance / help ... and let me know where am i going wrong ) .

TIA

Nitin

I am getting the following error :-

INSTALLING FFTW

;;;this is for double precision

#./configure --prefix=/opt/fftw332 --enable-shared --enable-threads --enable-sse2 --enable-portable-binary

#make

;;;This is for single precesion

LAPACK-3.2.0 INSTALLATION

#tar zxvf lapack.tgz

#cd lapack-3.2.1

#cp INSTALL/make.inc.gfortran make.inc


          >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
IMPORTANT :-
INSTALL ATLAS IN A BOGUS/TEMP DIR, WHICH YOU WILL DELETE AFTER DOING THE FOLLOWING:
"BOGUS INSTALL"

# tar zxvf atlas3.9.14.tar.bz2

# mv ATLAS ATLAS_tmp

# cd ATLAS_tmp

# /home/nitin/newpy/ATLAS-3.9.14/configure -Si cputhrchk 0 -b 32 -D c -DPentiumP4=1790 \
--dylibs -Fa alg -fPIC

           <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<

AFTER RUNNING THE ./configure (above), THIS WILL MAKE A make.inc FILE


EDIT LAPACK/make.inc : COPY from ATLAS_tmp (./configure creates) make.inc


SEARCH FOR THE FOLLOWING LINE AND Copy after = 

    F77FLAGS = -fomit-frame-pointer -mfpmath=387 -O2 -falign-loops=4 -fPIC -m32 -fPIC



PASTE into LAPACK/make.inc OPT= :


FORTRAN = gfortran -fimplicit-none -g
OPTS    = -fomit-frame-pointer -mfpmath=387 -O2 -falign-loops=4 -fPIC -m32 -fPIC
DRVOPTS = $(OPTS)
NOOPT   = -fomit-frame-pointer -mfpmath=387 -m32
LOADER  = gfortran -g
LOADOPTS= $(OPTS)


further down Un-Commnet the lines and add the path:


USEXBLAS    = Yes
XBLASLIB    = /home/nitin/newpy/xblas-1.0.248/libxblas.a
#XBLASLIB    = -lxblas


save and exit


#joe Makefile (nano/pico/vi)

edit 

  all: lapack_install lib lapack_testing blas_testing

save and exit

# make blaslib > blaslib.log

# make > make.log

# cp lapack_LINUX.a liblapack.a

# cp liblapack.a /home/nitin/newpy/Linux_P4ESSE2/lib/. (Overwrite? y)
;;; this liblapack.a = lapack_LINUX.a = 15MB approx (at least more than 6MB)


The following is in Makefile

   all:lapack_install lib lapack_testing blas_testing ;;; for the time being 
                                                      ;;; removed 'testing' &

ATLAS INSTALLATIONS INSTRUCTIONS

# tar jxvf atlas-3.9.14.tar.bz2

# mv ATLAS ATLAS-3.9.14  ;;; Rename the directory, convineant

;;; Turn off CPU throttling when installing ATLAS ,  Fedora 

# /usr/bin/cpufreq-selector -g performance

;;; On my Core2Duo, cpufreq-selector only changes the parameters of the first CPU, 
;;; regardless of which cpu you specify. I suspect this is a bug, because on earlier 
;;; systems, the remaining CPUs were controlled via a logical link to 
;;; /sys/devices/system/cpu/cpu0/. In this case, the only way I found to force the 
;;; second processor to also run at its peak frequency was to issue the following as 
;;; root after setting CPU0 to performance: 

 
   cp /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor \
      /sys/devices/system/cpu/cpu1/cpufreq/scaling_governor


# cd .. (one up dir)  ;;; Out of ATLAS-3.9.14 dir

# mkdir Linux_P4ESSE2 ;;; Make a new dir Or as.... Linux_C2D64SSE3 (Core2Duo)
