Linking lapack with my f77 code

[Zahra]

Hi all,

I should use subroutine ZGEEV in my code. But, while I am trying to compile my code

f77 -o result my-code.f -L/usr/lib -llapack -lblas

I got the following error :(

/tmp/cc4nQ0va.o(.text+0x152f): In function `MAIN__':
: undefined reference to `cmplex_'
collect2: ld returned 1 exit status

I am a complete newbie at using libraries. Can anyone help me?

Cheers,
Zahra

Your LAPACK or BLAS libraries may come from CLAPACK or CBLAS, in
which case you need additional f2c libraries.
Since you have a f77 compiler, the easiest for you is to download
and install LAPACK yourself with your f77 compiler then your compile
line should work.
