Compile Fortran with ARPACK in Linux
 

I want to use

gfortran test.f90 -lblas -llapack

to compile the file test.f90 and want to use arpack but there is an error message:



test5.f90: (.text+0x7d9): undefined reference to `dsaupd_'
test5.f90: (.text+0x990): undefined reference to `dseupd_'
test5.f90: (.text+0xbbf): undefined reference to `dmout_'

What is the code (like -llapack) to use arpack

Welcome to LQ.

Probably -larpack

I.e. you have e.g. /usr/lib64/libarpack.so
