Airsim: 'ERROR: UBT ERROR: Failed to produce item' when loading project into Unreal Editor

Created on 17 Sep 2017  路  19Comments  路  Source: microsoft/AirSim

Hi, I am working on a project involving training drones in a simulated environment. I am planning to use AirSim for this project. However, I am unable to load the Blocks environment into Unreal Editor. I would severely appreciate any help!

I am using a 2017 Macbook Pro with MacOS Sierra, and Unreal Engine 4.17. When I browse for and load the Blocks project, I get the following error on XCode (after choosing to Convert In-Place):

Most helpful comment

I've made few changes that will hopefully make OSX build more easier.

  1. Removed dependency of libudev header
  2. Removed -lgcc and -gcc_s flags

The compile error seems to be in rpclib. I've files issue at their github: I鈥檝e filed issue at rpclib: https://github.com/rpclib/rpclib/issues/154

I commented on rpclib/rpclib#154 @pratyushmore

@sytelus @sztomi Sorry for the late response - I was out of town. I will take a look at this now and let you know whether it worked out! Thanks!

Hi. I built the specified commit from the rpclib repo. (Do I have to rebuild AirSim or Unreal Engine or link this new rpclib installation somehow?)

Now, when I try to import the Blocks project into unreal editor, I get the following message:

This project requires the 'AirSim' plugin, which is not compatible with the current engine version.

Would you like to disable it? You will no longer be able to open any assets created using it.

I choose No. I get the following

The following modules are missing or built with a different engine version:

UE4Editor-Blocks.dylib
UE4Editor-AirSim.dylib

Would you like to rebuild them now?

I choose Yes.

After trying to build for some time, the Editor Crashes and a dialogue box says I should try rebuilding from source.

@sztomi Any tips on how I can proceed from here?

pratyushmore picture pratyushmore on 30 Sep 2017

@pratyushmore I have the exactly same issue with you. Have you figured out how to solve it? Thanks!

BoyuanChen picture BoyuanChen on 30 Sep 2017

@pratyushmore I just fixed it by reinstall libudev. If you do not have it before, try this one:

apt-get install libudev-dev

Hope this can help.

@BoyuanChen Hi. I have not yet fixed this. I will try to find the equivalent of libudev for macOS and install it. Will revert back as to whether this gets fixed.

Q: Did you rebuild AirSim after? Or did you rerun setup.sh as well?

Thank you so much for your help!

@BoyuanChen @sytelus @sztomi
Hello! The above solution works for linux but not Mac OS. I am planning to do a complete rebuild of AirSim. Is there any readme I could follow for Mac OS to ensure I am doing the right steps?

pratyushmore picture pratyushmore on 10 Oct 2017

No, we haven't tried AirSim on MacOS. So that's a great area we would welcome any contributions!

sytelus picture sytelus on 10 Oct 2017

@sytelus I feel I have been able to get through most things. However, I am now running into some problems with the build. I receive the following error:

ld: library not found for -lgcc_s
clang-3.9: error: linker command failed with exit code 1 (use -v to see invocation)
make[2]: * [output/bin/MavLinkTest] Error 1
make[1]: [MavLinkCom/MavLinkTest/CMakeFiles/MavLinkTest.dir/all] Error 2
make: ** [all] Error 2

Any ideas?

pratyushmore picture pratyushmore on 10 Oct 2017

@pratyushmore How did you manage to build the plugin? Mine is stuck at struct nil { }; and I have no idea how to fix it. The above commit did not work for me.

ProfFan picture ProfFan on 17 Oct 2017

Hi @ProfFan ,

I am instead using a Linux server. Installing as I type. Will update you.

pratyushmore picture pratyushmore on 17 Oct 2017

@pratyushmore Finally worked out everything. First you need to deal with ld: library not found for -lgcc_s, which you can just search in the source and delete -lgcc -lgcc_s. Second you deal with the nil issue by changing rpclib itself. Before upstream makes the change, you can see the corresponding commit in my repo. Be sure to change the files in external/rpclib. The code should now compile. If you encounter magic crashes, use my settings.json attached below.

After all that the code should run fine on macOS.

I am having the same problem on El Capitan.
I deleted the flags -lgcc -lgcc_s and I have modified the file nil.hpp as described by @ProfFan. When I import the Blocks project in Unreal I don't get any popup and after some time it fails with this error:

[2/361] Compile Module.AirSim.gen.cpp

@ProfFan how did you fix this on mac?

@alessandro-montanari I think I simply deleted this line or installed some brew package for it. Been out now, will update you in a few days, after I go back to work.

I've made few changes that will hopefully make OSX build more easier.

  1. Removed dependency of libudev header
  2. Removed -lgcc and -gcc_s flags

Can you confirm that building Airsim on mac is working by just changing external/rpclib?
I tried but Blocks environment build is always failing

Several more fixes for Mac build was contributed recently:

  • use latest rpclib
  • add brew install coreutils
  • use greadlink instead of readlink

Please try out the new version. Also, please file new issue so we can track it better.
