So I am using gcc git clone checkout from some days ago, and evidently scummvm may not have been tested with this - so I am just reporting it. Either way perhaps someone can have a look here, if this is solely related to C++ 20, as eventually that may have to be supported (with upcoming stable gcc releases perhaps).

I then tried to compile via gcc 10.5.0, as I noticed that I can compile more programs that way, using an older GCC. However had this led to another error:

I had the error:

install: missing destination file operand after '/home/Programs/Scummvm/2.8.1lib/scummvm/'

Before but did not report it. I think there is something
wrong with the build system scummvm uses, since I can
compile other GNU configure based programs just fine.

(And perhaps it would be time to switch to cmake or
meson/ninja; GNU configure is such a huge mess really.)

Thank you for reporting. We will try to look into the first one eventually.

In regards of the second bug, we do not use GNU configure, our configure is completely custom.

We never run make install, so no wonder it is broken, we'll look into that.

If you can rewrite our configure in cmake or meson/ninja so that it works on all 30+ supported platforms, you will be my hero.

@rubyFeedback: You are not clear, but given some of the paths, you are trying to compile on MacOS. Can you please provide full details of how you are compiling i.e. XCode, MacPorts or Homebrew and on what architecture i.e. PPC, x86 or ARM?

Our compilation instructions are here: ​https://wiki.scummvm.org/index.php?title=Compiling_ScummVM/macOS and ​https://wiki.scummvm.org/index.php?title=Compiling_ScummVM/Docker for reference ...

It should be noted that the normal Unix-y invocation would be "./configure && make clean && make" to build, but the instructions give further notes on required library dependencies etc. so you should check the ./configure output for any issues / missing library warnings before you go to make

I tried with gcc 14.2.0 and ran into multiple issues with compiling files from macOS frameworks.

In general, your logs clearly show that you are running your compiler in C++20 mode, while we require C++11.

It is not possible at this moment to look forward to adding support for a fresher compiler because one of the main goals of ScummVM as a project is portability.

Me and several other devs build ScummVM on macOS daily with clang, coming with Xcode Command Line utilities, so this option is always recommended and is covered in our build instructions:

Closing this as 'wontfix' for the time being.
