changes to be able to compile the plugin on linux. warning: you need …

[gonzaloaguilarjimenez]

Good afternoon,

I am writing this issue becasue I am trying to complie ROSIntegrationVision (after successfully installin ROSIntegration) for UE4 on ubuntu and I cannot.

My main problem is when I try to do:

_…to compile the unrealengine with -mf16c. To do this, open ./Engine/Source/Programs/UnrealBuildTool/Platform/Linux/LinuxToolChain.cs , find the GetCLArgumentsGlobal method and add Result += f16c; in a suitable place

I don't really know where is the suitable place or wether I have to write between " ".

Is it possible that you give me an answer?

Thanks a lot.

Best regards.

Hi, as the documentation says:

To do this, open PATH_TO_UNREAL/Engine/Source/Programs/UnrealBuildTool/Platform/Linux/LinuxToolChain.cs, find the GetCLArguments_Global method

Hence, go to the GetCLArguments_Global and add Result += " -mf16c"; somewhere inside that method. For example just before the return statement is a suitable place. Just c&p the command as it is here.

Good afternoon,

I did what you said above and a pop up window jumps into the screen saying:

Missing MyProjectName Modules The following modules are missing or built with a different engine version: LibUE4Editor-ROSIntegrationVision.so Would you like to rebuild them now?

Of course I click yes and then it tries to work on it and a second pop up window jumps into the screen saying:

Error MyProjectName could not be compiled. Try rebuilding from source manually.

Then the program crashes and sends me out.

Do you know what can be happening?

Thanks a lot.

Best regards.

If the compilation fails, we need your compile log to help you any further.

Source compilation on the ubuntu terminal or i.e. visual studio?

Should I compile whole ue4? From the beginning? The compilation is really long, what should I show you exactly?

Thanks.

Hi,

i guess the ubuntu terminal output of the project build process should do it.

And yes, you need to recompile engine:

"If you use this Plugin on Linux, you need to enable F16C support manually in Unreal Engine 4 and recompile it"

Finally I solve it recompiling UE4 from the beginning, even generating the projects' files.

It seems to be working.

I will do some more tests anyway.

Thanks very much.

Best regards.

Hello again,

It seems as I said some hours ago that I finally installed it, but I am not receiving the images in RVIZ (as you can see in the picture attached there is nothing received). I don't really know whether it is due to ROSIntegrationVision or due to ROSIntegration, although as you can see, ROSIntegration connects with UE4.

Could you please help me with this?

Thanks a lot.

Best regards.
