Installing different versions

[hanamilani]

Hi,

My question is: what is the difference in installing the new version of lapack.3.4.0 and the previous ones.Cause I always followed the following steps and had no problem:
% tar -zxvf lapack.tgz
% cd lapack-3.2/
% cp make.inc.example make.inc
% vi make.inc
% make all

Pls let me know what steps I should take for version 3.4.0 .

Thanks

Should be almost the same.
just do
%make blaslib
to create the Reference BLAS library then
%make

I did but received again the following error:

ok I see
in the make.inc
uncomment the second line, you should have

Code: Select all

# For gfortran compiler: SECOND and DSECND will use a call to the INTERNAL FUNCTION ETIME
TIMER    = INT_ETIME

well, in the previous versions I always had this edited in the make.inc:
TIMER = EXT_ETIME

Could I please know what differences they will have?

[admin]

It is to select the Fortran routine to use to time.
Fortran compilers do not have the same.
If gfortran is below your mpif90 call, then INTERNAL FUNCTION ETIME is the one to call.

it may seem wiered, but gfortran has always been below my mpif90 and I made lapack with TIMER = EXT_ETIME
why doesn't it happen with te new version?
