Compilation error

[Atrik]

I'm not able to compile a28 or main, the compilation fail with this error:

../../../source/scriptinterface/ModuleLoader.h:86:15:   required from here

Some time ago I already had this error when compiling main, and though it was because of some WIP, but now I'm guessing the problem is on my end since it's still here. What am I doing wrong? Debian build

Thanks

I don't think that the problem is on your side. But it's weird that nobody encountered this error.

Which compiler do you use?

Could you test this: https://gitea.wildfiregames.com/0ad/0ad/pulls/8528

I got an error like this a while ago too and the cause was that the compiler version was too old.

That do fix the error, but compilation fails later with another forward declaration and a bunch of new errors too.
I have clang 18.1.8, rusc 1.91.0

I think you are using gcc instead, if you want to use clang you have to set CXX environment variable or pass --cc=clang to update-workspace.sh, also your gcc version is likely older then gcc-12.

Thanks, so what I've tried now is : 

./update-workspaces.sh --cc=gcc-12
cd gcc
make

And

./update-workspaces.sh --cc=clang-18
cd gcc #Can't see any other folders
make

 

If i pass a compiler version i don't have to update-workspaces.sh, it tell me so. Therefor I'm guessing i do have to compiler I'm passing above.
Yet compilation fails in both cases.
 

With gcc 

/usr/include/fmt/core.h:2201:22: error: ‘constexpr void fmt::v8::basic_format_parse_context<Char, ErrorHandler>::on_error(const char*) [with Char = char; ErrorHandler = fmt::v8::detail::error_handler]’ called in a constant expression
 2201 |     context_.on_error(message);

With clang
