t-nissieの日記： How to avoid "/usr/bin/ld: cannot find -lblas" error

feram のコンパイルのときに

/usr/bin/ld: cannot find -lblas

ってエラーになって困って、
ググったら解決方法が見つかった話。

Dear feram users,

I encountered “/usr/bin/ld: cannot find -lblas” error,
when I did "./configure" for feram-0.18.05 on CentOS 6.2,
though I surely installed /usr/lib64/libblas.so.3.

I found solution for it in
http://linuxtoolkit.blogspot.jp/2011/11/cannot-find-llapack-when-doing-usrbinld.html.

Here, I summarized:

=== CentOS 6.2 (feram-0.18.05, 2012-03-28)
CentOS 6.2 can be installed to your x86_64 system with DVD and
CD-ROM images in http://isoredirect.centos.org/centos/6/isos/x86_64/ .
 
Network installation is also available with a CD-ROM image of
CentOS-6.2-x86_64-netinstall.iso. See
http://www.if-not-true-then-false.com/2011/centos-6-netinstall-network-installation/
for more details.
 
Select "Software Development Workstation" in the setup.
 
==== check the version of gfortran
  $ gfortran --version
  GNU Fortran (GCC) 4.4.6 ...
 
==== install fftw-3.3.1.tar.gz
  $ tar zxf fftw-3.3.1.tar.gz
  $ cd fftw-3.3.1
  $ mkdir CentOS
  $ cd CentOS
  $ ../configure --prefix=/usr/local --libdir=/usr/local/lib64 --enable-openmp --enable-threads --enable-sse2 --enable-avx --enable-shared
  $ make check
  $ su
  # make install
  # exit
 
==== install BLAS and LAPACK
  $ su
  # yum install blas.x86_64 lapack.x86_64
  # cd /usr/lib64
  # ln -s libblas.so.3 libblas.so
  # ln -s liblapack.so.3 liblapack.so
  # exit
Symbolic links are for avoiding error of "/usr/bin/ld: cannot find -lblas".

==== compile feram
  $ export LD_LIBRARY_PATH=/usr/local/lib64   # Do not forget it.
  $ tar Jxf feram-0.18.05.tar.xz
  $ cd feram-0.18.05
  $ mkdir CentOS
  $ cd CentOS
  $ ../configure --help
  $ ../configure
  $ cd src
  $ make
  $ make feram_mpi   # OPTIONAL
  $ ls -l feram*
  $ ldd feram
