Error when opening a project using this plugin

[samcaulfield]

Hi,

I am receiving this error when I start a project that uses this plugin:

Clicking "No" results in this error:

My setup is Ubuntu 16.04.3 with Unreal Engine 4.18.2.

I set up Unreal Engine using the following steps:

git clone https://github.com/EpicGames/UnrealEngine.git
cd UnrealEngine
git checkout "4.18.2-release"
./Setup.sh
./GenerateProjectFiles.sh
make
cd Engine/Binaries/Linux
./UE4Editor
<Created a project called ROSIntegrationTest then exited the editor>

I set up this plugin using the following steps:

cd ~/Documents/Unreal\ Projects/ROSIntegrationTest
mkdir Plugins
cd Plugins
git clone https://github.com/code-iai/ROSIntegration.git
cd ~/UnrealEngine/Engine/Binaries/Linux
./UE4Editor

Here is the UE4.log generated by this attempt.

I'm new to Unreal so perhaps I'm making a rudimentary mistake. Any help you could provide would be appreciated.

Thanks

Hi!
Thanks for the bug report.
This might be related to #17.

I'm investigating the issue right now by installing the plugin and compiling it from scratch.

However, can you please tell me which kind of Unreal Project you've created?
A C++ or a Blueprint version?

The project I created was a Blueprint-based one using the "First Person" example.

I just created a C++ version of the "First Person" example and it seems to work fine. The editor starts up and I can see the plugin in the plugins list.

Hi @samcaulfield

Thanks for the report. I was also just testing this and i'm suspecting that the Plugin will not be compiled because a blank Blueprint project will not invoke the build process.
iirc, you can also start with a Blueprint project, but i guess you have to have atleast one C++ class. This will instruct the build process to compile the whole project which should also fetch the code of the plugin.

OK. Thanks for looking into it and the explanation of the cause of the problem.
