Hello,

I'm using a third party template library called "entt".

For certain methods of that library, Eclipse shows errors for perfectly fine code, see attachment.

The code compiles without errors and warnings perfectly well. I'm using MinGw as toolchain, am I missing a certain setting?

Rather hard to say since you didn't really tell us what you did.

This is a question often asked.
You need to understand that Eclipse is separate from the toolchain.
The toolchain is provided by a third party and is external to Eclipse.

Eclipse uses the toolchain only during the build (with one exception).
It normally does this through the Makefile assuming you are using Make.
If Eclipse is creating the Makefile,
then you tell Eclipse to tell the compiler where the includes can be found.

You seem to have done this because the code compiles without errors.

If you want Eclipse to check your syntax and function calls then you need to inform the Indexer about your includes.

There are many ways to do this.

Thank you for your response.

Include paths are correctly set up. I can even use the structures and methods defined int the .hpp.

It seems for complex operations where methods are nested in combination with the "auto" keywoard, Eclipse just can't resolve that and tells me that are unknown symbols.

Could be.
All of the flagged errors after auto group appear secondary.
So you only need to find out why it's flagged.
I don't have any way to reproduce this.
Suggest filing a bug report.
