Now, we are needing to set the LAPACK Make.inc appropriately. First,
I go into the LAPACK directory, and copy the platform-specific make.inc
to make.inc. In my case this is:
animal>cd lapack-3.1.1/ animal>cp INSTALL/make.inc.LINUX make.inc
I now edit the created make.inc (vi make.inc), and here are
the make macros that I change:
FORTRAN = <want to set to ATLAS's F77 macro> OPTS = <want to set to ATLAS F77FLAGS macro> DRVOPTS = $(OPTS) NOOPT = <F77FLAGS w/o optimization> LOADER = $(FORTRAN) LOADOPTS = $(OPTS) TIMER = <need to know what compiler I'm using to set>
So far, I have only been able to fill in DRVOPTS, LOADER and LOADOPTS, which are defined in terms of the macros I've yet to fill in! The reason is that I want to use the same compiler and flags as ATLAS, so that I'm sure my LAPACK library can interoperate with my ATLAS-tuned library. I will set the FORTRAN macro to the compiler indicated by ATLAS's F77 macro, and OPTS will be the same as F77FLAGS.
So, I change to the ATLAS source directory, and produce a dry-run BLDdir
in order to get this information by:
animal>cd ../ATLAS3.7.38/ animal>mkdir bogus animal>cd bogus/ animal>../configure -b 64 -D c -DPentiumCPS=2200 -Fa alg -fPIC ................................................... ............<A WHOLE LOT OF OUTPUT>................ ................................................... animal>fgrep "F77 =" Make.inc F77 = gfortran animal>fgrep "F77FLAGS =" Make.inc F77FLAGS = -fomit-frame-pointer -mfpmath=387 -O2 -falign-loops=4 -fPIC -m64
With this info in hand, I am ready to delete this
bogus directory, and go back and edit the LAPACK make.inc:
animal>cd .. animal>rm -rf bogus/ animal>cd ../lapack-3.1.1/ animal>vi make.inc
I now fill in my make.inc macros as:
FORTRAN = gfortran OPTS = -fomit-frame-pointer -mfpmath=387 -O2 -falign-loops=4 -fPIC -m64 DRVOPTS = $(OPTS) NOOPT = -fomit-frame-pointer -mfpmath=387 -m64 LOADER = $(FORTRAN) LOADOPTS = $(OPTS) TIMER = INT_ETIME
I chose the setting of TIMER based on the fact that the example file's comments said it is the correct setting when the compiler is gfortran.
Now I perform the LAPACK install:

So, we have succesfully created the LAPACK library, and now we need to install ATLAS and a complete LAPACK using it.
