[VIDEOTUTORIAL] How to fix fmt::v10::format_error and static_assert failed on TFS 1.5 (8.6 downgraded by Nekiro)

[ralke]

Hi everyone! I've been asked a lot on how to fix fmt::v10::format_error and static_assert failed for every fork based on TFS 1.5 downgrades 8.6. In the same way I did on this tutorial I simply recorded a fix service for @visceraL (unfortunately he doesn't have otland account) to share it and help people compiling their own servers. So, here we go:

For this tutorial we're going to use the following @Sarah Wesker commit

fix fmt exception · Unreal-TFS/forgottenserver@bb9635e

A free and open-source MMORPG server emulator written in C++ - fix fmt exception · Unreal-TFS/forgottenserver@bb9635e

github.com

The tutorial also have an extra tip of how to fix missing libraries, in this case we can't include filesystem.hpp because there's no such file or directory. To fix this we used "show potential fixes" and run the following command line in GitBash.

./vcpkg install boost-filesystem:x64-windows

Thanks for watching, and please subscribe to YouTube (will help me a LOT)
Regards!

At minute 2:50 we go to Sarah's repository. Instead of using that fix, I suggest to use the one that has been officially merged to theforgottenserver, that is this one Add extra & pedantic warnings and fix the code by ranisalt · Pull Request #4491 · otland/forgottenserver (https://github.com/otland/forgottenserver/pull/4491/files), both will work anyways

Hey, I've just followed the Compiling on Windows (vcpkg) (https://github.com/otland/forgottenserver/wiki/Compiling-on-Windows-%28vcpkg%29) tutorial. I've succesfully went through all the steps, however when I tried building the Nekiro 1.5 TFS 7.72 downgrade i've encountered few errors: Severity...

You just need to switch back this commit Drop boost::filesystem in favor of std::filesystem (#3990) · otland/forgottenserver@4b800b2 (https://github.com/otland/forgottenserver/commit/4b800b20558f24344c5024fb3cb9a4974ebad90e)
And return to old boost-filesystem.hpp. Here's a video troubleshooting the error with @Sanjao, tell me how it goes
