macOS Compiling 1990s fortran code on macOS Catalina

[AeroEngineer]

Hey y'all!

For my studies I need to use three different command line programs written in Fortran by an MIT prof. Two programs (the freely available XFOIL and AVL) are already available pre-compiled for macOS, but these are not the latest version. The third one, MSES, is not freely available (I have an academic license for it) and only contains a compiled Windows version and the source code.

Now I have been trying for some time to get all latest versions to compile through various web searches, but I always get stranded somewhere along the way due to different errors. I did find this post from 2014 describing how to compile, but even that gives me errors.

Is there anybody here who has previous experience with compiling these or similar programs? What's the 'best' way to compile these programs? Should I use an old release of GCC (I have the newest version installed)? Please note, I have zero experience with (compiling) Fortran..

Before anybody suggests to 'just use the pre-compiled/windows versions', A) compiling the code myself gives the option to get double precision results and B) my whole python/MATLAB workflow is setup on my Mac and I do not have any access to Windows at the moment.

Any help would be greatly appreciated!

Thanks in advance,

Rod

Hi there. When you say you have an academic license did that still cost something, or could I as a university student download it for free? Much easier to have the source, compile it, work through potential errors and then tell you something I know works than to trial and error it with you

In any case; did you get GCC with brew install GCC?
Then try gfortran -o <NameOfOutputFileHere> <NameOfInputHere>

What errors do you get?

If you are familiar with C, one alternative would be to use one of the Fortran to C conversion programs.

Hi! Thanks for your quick reply!

I got my license for MSES through my department at university. The software is also available for purchase for commercial use. Sorry for the confusing.

XFOIL and AVL source codes are freely available through the links I posted.

Let me try again and take some screenshots of the errors

I can complete the first step of the general readme of XFOIL (Build Orr-Sommerfeld database).

When trying the second step, building the plot library, I type the following commands:

$ cp config.make.gfortranDP config.make
make
make install
make test

All of 'm except the last seem to work. I get the following code when running the last:

$ make test

Then, when I try to compile the programs

$ cd ../bin
open Makefile

I get this:

Do note, I did change directories in the source code to the ones on my MBP and commented out the irrelevant compilers.

 

[casperes1996]

The error message would normally sound like a programming error to me. The warning messages earlier makes it seem like, in spite of its age, Fortran has changed enough that language changes may be the cause here, and likely the programmer behind this used less than 100% recommended practices.
I guess you could try an older gcc yeah. With brew you can just brew install gcc@version-number normally. Or do a brew search gcc to see what’s available.

I’ve never really done Fortran - If READR is a library function and not a function in the program there’s also a chance the dependency has changed or is different on macOS. Could try inside a docker container for Linux to see if that works

Okay, so I managed to download an older version of gcc (thanks for the hint!) and actually got through to the last step!

Then I get this error:

A quick Google search makes me think it is not finding certain fortran libraries? Could be wrong though..

Right there the linker is basically not finding any libraries at all.

You have a linker error there. You probably need an explicit link line. If they're just simple defines, then it might be a wrong language version or compiler front end invoked.

Recall that Fortran has many versions. You need it to compile for an older version of Fortran that matches the language spec it was written for, assuming they weren't strict supersets.

Similar issues show up in macports.

#58646 (libgcc @2.0_1: should not be noarch for dependents architecture compatibility checking) – MacPorts

trac.macports.org

If I really wanted to track this down, I would check what library actually defines those symbols. Digging through compiler source is time consuming though.

OP - did you ever get this resolved?

OP - did you ever get this resolved?

Unfortunately no (not yet). Haven't looked at it since last week though as I've been busy with the start of the academic year. I'll try to get back to it next week and see if I can get rid of the linker error.

Your last set of diagnostics almost looks like your compiler package is not connecting correctly with system libraries. I use Macports for their compiler collection, including gfortran, and that requires that the command-line tools for Xcode be installed on your system prior to installing the gcc compilers. I don't know about the compilers from brew, but I suspect there may be a similar need.

Brew itself requires the Xcode Command Line tools, yeah. A lot of packages for macOS come from the Xcode installer
