Compilation Issue - GCC 12.2.1 - Fedora 37 - error: conflicting types for ‘getopt’

I am attempting to compile the code under GCC 12.2.1 on Fedora 37, but I am running into an issue.

Just as the instructions suggested, I ran ./configure followed by make. Here is the output from ./configure

Then here is the output from ./make with the 'getopt' related issue.

Do you happen to have any ideas on how to get around this?

It appears there is a custom version of getopt (getopt.h, getopt.c) that is used with bigbang.c for universe generation. Is this custom version of getopt necessary when running with a modern version of c? If not, what is the easiest way to disable it?

Compilation Issue - GCC 12.2.1 - Fedora 37 - make: *** No rule to make target 'configure.ac', needed by 'Makefile.in'. Stop.

Rick,

When I attempt to run any of the make commands, I now get the following issue.

(base) [anthony@fedora twclone]$ make
make: *** No rule to make target 'configure.ac', needed by 'Makefile.in'.  Stop.

Here is the output from my execution of ./configure. I am not sure if anything has changed.

Thank you for much for your helping me try to get this code compiled!

FYI, I expect GCC on Fedora should operate similarly to your install on Linux Mint. I imagine whatever issues remain are probably minor. I am just not sure how to resolve them.

./gen file specified in README.md for regenerating Makefiles does not exist.

The referenced file ./gen in the README.md file does not seem to exist.
