Title: FEAPpv with 64bit integers
Post by: JStorm on June 01, 2018, 03:22:47 AM

I have tried to compile FEAPpv 4.1i for 64bit integers:

• GNU compiler with "-fdefault-integer-8"
• ipr = 1

.

This failing, because in filargs.f the defined integers are forced to 32bit. Is there a need to have 32bit integers there?

you can promote the KIND using added option -finteger-4-integer-8

they can be integer*8

Thank you Prof. Taylor.

There is a bit of danger in using -finteger-4-integer-8 since there are a few places in the code where real*4 is needed.  So it may be better to edit filargs.f instead of using the blanket change of -finteger-4-integer-8.
