make on a ROCKS/CENTOS 5.6 system

[margaret]

The make of lapack-3.4.0 fails on my system. I used the default make.inc.

I issued

make

The process ends in

gfortran -O2 -c dlarnd.f -o dlarnd.o
ar cr ../../libtmglib.a slatms.o slatme.o slatmr.o slatmt.o slagge.o slagsy.o slakf2.o slarge.o slaror.o slarot.o slatm2.o slatm3.o slatm5.o slatm6.o slatm7.o slahilb.o clatms.o clatme.o clatmr.o clatmt.o clagge.o claghe.o clagsy.o clakf2.o clarge.o claror.o clarot.o clatm1.o clarnd.o clatm2.o clatm3.o clatm5.o clatm6.o clahilb.o slatm1.o slaran.o slarnd.o dlatms.o dlatme.o dlatmr.o dlatmt.o dlagge.o dlagsy.o dlakf2.o dlarge.o dlaror.o dlarot.o dlatm2.o dlatm3.o dlatm5.o dlatm6.o dlatm7.o dlahilb.o zlatms.o zlatme.o zlatmr.o zlatmt.o zlagge.o zlaghe.o zlagsy.o zlakf2.o zlarge.o zlaror.o zlarot.o zlatm1.o zlarnd.o zlatm2.o zlatm3.o zlatm5.o zlatm6.o zlahilb.o dlatm1.o dlaran.o dlarnd.o

How do I get this package installed?

[admin]

Just type make blaslib to get the Reference BLAS.
Then make again to finish compiling and running the LAPACK testings.
If you want a optimized BLAS library, I would suggest ATLAS, MLK, GOTO BLAS, etc.. more info here: http://en.wikipedia.org/wiki/Basic_Line ... ubprograms

Could you please copy/paste the error.

Respected Admin,
I have installed lapack-3.4.0 in my centos system. I had followed what admin has suggested.
downloaded lapack-3.4.0.tgz file
then gunzip -c lapack-3.4.0.tgz | tar xvf -

somenath@Binder@Downloads$cd lapack-3.4.0
somenath@Binder@lapack-3.4.0$cp make.inc.example make.inc
somenath@Binder@lapack-3.4.0$make blaslib
somenath@Binder@lapack-3.4.0$make

then this came at last on the screen of terminal.

S I think its installed perfectly.
Now when I try to run a code

somenath@Binder@~$gfortran main.f90 -llapack -lblas
/usr/bin/ld: cannot find -llapack
collect2: ld returned 1 exit status
somenath@Binder@~$

So can you please help me in this matter.
One more thing.
When I do

make[1]: Leaving directory `/home/somenath/Downloads/lapack-3.4.0/BLAS/SRC'

Can you help me here also?
Thanks a lot.

[admin]

somenath@Binder@~$gfortran main.f90 -llapack -lblas
/usr/bin/ld: cannot find -llapack
collect2: ld returned 1 exit status

Try gfortran main.f90 -L/home/somenath/Downloads/lapack-3.4.0 -llapack -lrefblas

( cd BLAS/SRC; make )
make[1]: Entering directory `/home/somenath/Downloads/lapack-3.4.0/BLAS/SRC'
ifort -O3 -c isamax.f -o isamax.o
make[1]: ifort: Command not found

You do not have the INTEL Fortran compiler: ifort installed on your machine.

Now after struggling with the installation process, I am facing this problem with both gfortran and ifort. Can somebody give me a hint?
