RiderLink / UnrealLink issues - Linux - UE 5.7

[AStoicBoy]

Hi!

I am writting here as I am unable to find an answer to my issue, since the latest Unreal Engine update (5.7), my Riderlink is dysfunctional

I feel like I have tried everything possible around the plugin, but my only option as for now is to hide intellisense. I am currently using RIder 2025.3.0.2.

Would anyone have the same issue? Is there any fixes?

I have seen on another thread the following:

" On first glance it seems that upgrading to a new version of spdlog fixes it, as the bundled fmt library was upgraded, which caused these issues.

https://github.com/gabime/spdlog/releases/tag/v1.16.0
https://github.com/fmtlib/fmt/releases/tag/12.0.0 "

Which I did, but it didn't change anything.

Any help would be greatly appreciated!

I had this issue but I recently updated to Rider 2025.3.0.3 and I don't seem to have this issue anymore. I am also using UE 5.7.1 pulled from Github and built it from source. First clean install of RiderLink into the Engine Plugins Directory didn't seem to throw the errors anymore.

Thank you for your feedback, I tried, pulled 5.7.1 and installed in Engine and yet, I have the exact same issue.

There is a ticket on jetbrain website there: https://youtrack.jetbrains.com/issue/RIDER-133226 , it seems that we are several persons to have this issue and it is currently under fixing :)

While we are waiting for a fix from JetBrains, there is a workaround to solve the compilation issues:
antidotcb/RiderLink-5.7-compile-fix@6645598

First, you have to go to Settings -> Languages & Frameworks -> Unreal Engine and press Extract RiderLink in Game button (optionally into the Engine):

After that, apply the diff from my repo commit to the sources and build. It works fine for me.

Or instead you can run the following commands from the Plugins/Developer/RiderLink directory:

cd Plugins/Developer/RiderLink
find . -type f -print0 | xargs -0 sed -i -E 's/operator[[:space:]]*""[[:space:]]+/operator ""/g'
find . -type f -print0 | xargs -0 sed -i -E 's/define FMT_CONSTEVAL consteval/define FMT_CONSTEVAL/g'
find . -type f -print0 | xargs -0 sed -i -E 's/\bdefine[[:space:]]+FMT_HAS_CONSTEVAL/undef FMT_HAS_CONSTEVAL/g'

Platform: EndeavourOs, UE 5.7.1-release branch built from source, Rider 2025.3.1

After upgrading to UE 5.7.1 I get intellisense errors in Rider

Example:
Cannot resolve symbol 'remove_reference_t'
From:
UE_LOG(LogSilverkeep, Log, TEXT("Primary action, not facing target"));

This applies to all c++ std library imports as far as I can tell

Another example:
void EntitySystem::SetCreatureBiography(uint32 EntityID, const std::string& Biography)

Error: Cannot resolve symbol string

This is only for intellisense in rider. Compiles are fine.

Steps taken for resolution:

Complete clean and reinstall of ue 5.7.1 twice including cleaning config and .local and home folders of any ue, epic folders
Complete cache clear for rider
Clean .idea and .run folders
Regenerating project files
Reinstall riderlink plugin applying the patch mentioned above
Rider -> Help -> Check for updates -> All plugins updated including UnrealLink

I have no idea why but rider intellisense is not respecting the includes in my project, yet the includes are being correctly passed to the compiler
