- Subject: Mixing g77 and gfortran object code
Should I expect a binary built from a mix of g77 and gfortran object code, generated from F77 source, to work?
Are there compiler flags to assist the process?
Why is he doing this, you ask? I am investigating some gfortran LAPACK failures on cygwin.
In the past I have been able to isolate g77 LAPACK failures by progressively replacing
routines compiled with a known good compiler with those compiled with the suspect compiler.
Some initial testing shows that mixing and matching works in some cases, once I linked in
libg2c.a
