Build fails on 25.10.2

[decryptedchaos]

This simply wont build on 25.10.2

I have read the following issues, they provide no working solution.. and i do have the MultiplayerPhysicsX5 enabled as well

I have tried building individually this also fails.

#7

#6

cmake --build build/linux --target FPL.GameLauncher FPL.HeadlessServerLauncher FPL.ServerLauncher FPL.UnifiedLauncher Editor --config profile

I haven't built it against 25.10.2 yet, I'm still on 25.10.1, though that's unlikely to be the cause.

It looks like you're using Clang++ version 20, mine is 21.1.8. You can do clang++ --version to get the exact version.

What version do you have for ld? I have 2.45.1.

What version do you have for cmake? I have 3.31.10.

O3DE 26.04 will be coming out relatively soon, which will use PhyX5 for the multiplayer gem. At that point I'm going to drop the MultiplayerPhysicsX5 gem.

[decryptedchaos]

clang version 20.1.8

ln (uutils coreutils) 0.2.2

GNU ld (GNU Binutils) 2.45

cmake version 3.31.6

Yeah i know 26.04 is coming soon, hopefully that fixes a lot of stuff, its quite hit or miss on Linux

@decryptedchaos by the way, the MultiplayerPhysicsX5 gem is optional now, so you could try to build your project without it.

Also, could you try creating a new project using the default template and enabling the FirstPersonController gem?
