Can't compile for Linux using Unreal

juaxix

This time, I'm trying to compile Photon for Linux using crosscompile, had you ever try before and got these errors?:

And how to fix it?
Thanks!

Hi @juaxix.

Does the info from this thread help?

Yes I saw this post, but I don't know how to add flags to the compiler, maybe it's in the xml config?

https://docs.unrealengine.com/en-US/Programming/BuildTools/UnrealBuildTool/BuildConfiguration/index.html

this is the compiler used :

https://docs.unrealengine.com/en-US/Platforms/Linux/GettingStarted/index.html

version 4.22 -> v13 clang-7.0.1-based

I am afraid that I don't know either, how to do that in Unreal Engine. The Unreal Engine staff in their support forum should be able to tell you if and how this is possible.

Ok, looks like you have to recompile the unreal build tool to add commands...but it compiles in linux native directly, so far so good.
