用intel fortran compiler编译一个程序：
ifort -O2 -L/usr/lib -larpack -llapack -lblas -lg2c Migration.o -o
migration.out
出错信息：
IPO link: can not find -larpack
IPO link: can not find -llapack
IPO link: can not find -lblas
IPO link: can not find -lg2c
IPO Error: unresolved : dsaupd_
Referenced in eigen_spectrum.o
ld: cannot find -larpack
可是那些库文件都在/usr/lib/里呀：
$ ls /usr/lib/libarpack.

create a link file libarpack.so to libarpack.so.2 or libarpack.so.2.1.

It will be odd there is no libarpack.so already there, unless the libraries
are not installed completely. My guess is libarpack.so is a link to libarpack.
so.2 and libarpack.so.2 is a link to libarpack.so.2.1.
As I suggested in Linux board, check your LD_LIBRARY_PATH first. If no
libarpack.so in the directory, as kyte pointed out, make a link. Probably you
don't have write permissin in /usr/lib if you are not admin. That's fine, just
create the link in build directory, but make sure to use abso
