I'm currently trying to install ARPACK so that I can use sparse matrices in Armadillo for large information networks. The instructions for

However, when I try running make lib after altering the directory the files are in, but I run into trouble with this line of the README

7. Do "make lib" in the current directory to build the standard library 
   "libarpack_$(PLAT).a"

In the subfolders, there are only four different files for platforms, which are

ARmake.CRAY
ARmake.SGI
ARmake.SP2
ARmake.SUN4

The default is SUN4, and the file for the platform must exist because of the line

ARPACKLIB  = $(home)/libarpack_$(PLAT).a

included in the makefile. However, my computer has Sandy Bridge architecture (Ubuntu 12.04) and I'm not sure if I'm supposed to use that file.

Additionally, I get the following error after running the make lib command (which is make all in this context):

me@mycomp:~/devel/ARPACK2/ARPACK$ make lib
Making lib in /home/me/devel/ARPACK2/ARPACK/BLAS
/bin/sh: 6: /bin/make: not found
Making lib in /home/me/devel/ARPACK2/ARPACK/LAPACK
/bin/sh: 6: /bin/make: not found
Making lib in /home/me/devel/ARPACK2/ARPACK/UTIL

ranlib: '/home/me/devel/ARPACK2/ARPACK/libarpack_SUN4.a': No such file
make: *** [arpacklib] Error 1

I just installed LAPACK and OpenBLAS using make, but for some reason I'm running into issues here. I'm not very experienced installing libraries, but the documentation I've come across hasn't helped me get past this point.

  • is there a reason for installing ARPACK manually? there are pre-built packages for Ubuntu, as well as other Linux distributions. simply look for it in the Ubuntu software center. It might be called arpack-ng. – mtall Apr 19 '14 at 07:33

In ARmake.inc you need to change line home = $(HOME)/ARPACK if you want to build it to some other location (as written in the README file). libarpack_$(PLAT).a will then be stored there, e.g. /home/username/arpack/ARPACK

Also change PLAT = LINUX.

and the errors you see are due to the incorrect location of make.

In ARmake.inc, update MAKE = /usr/bin/make to the correct location of make.

You need to locate your "make" command, probably it is at /usr/bin/make. In ARmake.inc you must to especify correct path to "make" command.
