Target 'utils' is not a component of dart.

[jiapei100]

ENV:

Ubuntu 16.04.1
GCC 5.4.0
dart : today's dev (git clone)

During configuration,

 CMake Error at cmake/Components.cmake:112 (message):
   Target 'utils' is not a component of dart.
 Call Stack (most recent call first):
   dart/gui/CMakeLists.txt:30 (add_component_dependencies)

How to resolve this dependency?

Cheers
Pei

I have no problem building the current master branch in the same environment. Could you let me know how exactly did you build DART (e.g., commands)? Also, providing the whole output during the configuration would be helpful.

I also got this error while compiling. refers to the root directory of a catkin workspace. Here is my configuration output:

-- Configuring incomplete, errors occurred!

Thank you for the reporting. I could reproduce the issue based on your configuration output, and am working on it.

[cyberguy42]

If it helps, I was able to avoid the error by installing tinyxml2.

[jslee02]

Yes, it helps. The main reason of the error was that DART attempts to build dart-gui component while dart-utils is not built that is a dependency of dart-gui. I believe #880 fixes this.
