gfortran error : Unexpected element '<' in format string

问题

I suffer the pain to compile the old fortran source code using gfortran. I did not have many experience to do this, so please help me to correct the source code based on the error message.

disturbance.f:1416.31:

1505 format ( I7, E12.3, < npftu>E10.3 )
Error: Unexpected element '<' in format string at (1)

please note that there is no space between npftu and < >.

Thanks a lot.

回答1:

Variable FORMAT expressions are non-standard and are not supported by gfortran (link to the documentation).

I know your pain - I've also struggled with this problem many times before until I migrated completely to another compilers collection...

Thanks. The easier way for me is just to know the columns for npftu. In my case, I use 10 here, so the new code would like: 1505 format ( I7, E12.3, 10E10.3 )
