only those two sorts of libraries have and link to 3gf version of .so
(including both reference netlib blas and ATLAS blas, lapack).
On the other side, redhat distributions -lblas links to libblas.so and
-llapack links to liblapack.so.
Is there anyone who can clarify why debian uses .so.3gf only for -lblas
and -llapack?
Actually I found in debian libblas.so - libblas.so.3gf ultimately��
What is relationship between the two?
This is a remnant of the gfotran transition. During the transition, a
.3gf was added to libraries and package names for allowing a
distinction between the g77 generated libraries and gfortran generated
ones.
From your perspective, the fact that the file names have a 3gf should
not affect functionality at all. If it does, please let me know.
For more information on the gfortran transition which happened ~ 3
years ago, see http://wiki.debian.org/GfortranTransition
