gfortran

Where would I post a request for something I would like included in the next release. Namely the ports and packages to access gfortran.

Before posting requests you use the search, e.g. on freshports.org: https://www.freshports.org/lang/gcc/ (check pkg-plist).

I don't think there is a port/packages

psearch gfortran

devel/linux-c7-libgfortran Runtime libraries for gfortran (Linux Centos 7.9.2009)

That likely requires lots of Linux dependencies and other fortran programs common from Linux.

psearch -c lang fortran

lang/lfortran             Modern interactive Fortran compiler built on top of LLVM
...
lang/ratfor               Rational FORTRAN compiler

On FreeBSD, it may be better to use lang/lfortran.

we mounted packages per https://www.freshports.org/lang/gcc/ and it appeared gfortran is mounted as a result of that. However it appears it is a later version that does not include ansi fortran 77. We have source file coded per ansi fortran 77. The code runs seamless with no error messages on other os and produces an executable that is just so. When we try to compile that source code on freeBSD we get error messages and it doesn't compile. we used gcc fn and gfortran fn. we used the FtoC utility to get a C file, When we tried to compile the C file we again got error messages.
The thing is, there is a lot of code out there written per ansi fortran 77 that is used all the time. And many many people code in ansi fortran 77. So would it be possible to get the ports and packages required for ansi fortran 77 so that if someone wants to use the ansi fortran 77 compiler on freeBSD they can.

Looking at https://gcc.gnu.org/fortran/ and reading gfortran12(1) man page there's a --std switch that allows you to select the standard (you likely want legacy?).

You need to provide a link to the compiler source, at least.

yeah this legacy angle is interesting we will try it. to compile it might be: gfortran -std=legacy fn? I don't understand what you mean by --std

Yeah, one too many dashes, sorry. And -std=legacy sounds about right.
