Problem to compile with g77 a program which was normally compiled with Absoft compiler
in [Fortran]

Prev: data types inside interface
Next: If I get "undefined reference to `mp_barrier_'", which MPI library do I need to link with?
From: lappis bike on 30 Jul 2010 05:20 Hello, I get the following error messages when I try to compile a program with g77 somefile.f:(.text+0x93): undefined reference to `for_open' somefile.f:(.text+0xf4): undefined reference to `for_write_seq_fmt' somefile.f:(.text+0x128): undefined reference to `for_write_seq_fmt_xmit' somefile.f:(.text+0x454): undefined reference to `for_read_seq' Could you help me to fix this? I have posted more details about my actions on http://stackoverflow.com/questions/3365742/f77-problem-to-compile-with-g77-a-program-which-was-normally-compiled-with-absof Thank you

The details to which you refer show that you seem to be mixing libraries from 3 different compilers together (g77, gfortran and ifort); the answers given at the above link should help you a lot with diagnosing your problem. Since you have gfortran on your system why don't you use it to build your program rather than g77 which is old and unsupported on most modern systems. Simon |
