CLAPACK on latest Fedora/Ubuntu

Postby audityasharma » Fri Aug 02, 2013 7:03 am

Hi All,

I had installed CLAPACK on my computer which had an earlier version of Fedora; recently it was upgraded to the latest version. But now when I try to install it with exactly the same method as before, the system all but completes the install but fails inside the TESTING directory. Today I was trying to install CLAPACK on another machine which has ubuntu, and it appears to be the same problem. It exits from the TESTING directory with the following message:

NEP: Testing Nonsymmetric Eigenvalue Problem routines
./xeigtstz < > znep.out 2>&1
/bin/sh: line 1: 46972 Segmentation fault ./xeigtstz < > znep.out 2>&1
make[1]: *** [znep.out] Error 139

When I try to just do make inside the TESTING directory, I get a similar but variable error.

It seems that despite this failed test, I can actually use certain of the simplest eigenroutines like dsyev, and it apparently gives correct result. But I am nervous to use it when I know that the installation did not quite go completely OK.

Any help to solve the problem would be gratefully received.

CLAPACK is no longer maintained.
PLease use LAPACKE (the C Wrapper to LAPACK) included in the LAPACK distribution. More info here
LAPACKE has actually been integrated in RPM Fedora : ... 6.rpm.html
