Hi @stilong,

You have uncovered the existence of some residual CMake code that should have been removed when the submodules where deleted from this repository here in #25. While we remove this code, you can try anD build ShapesDemo without the EPROSIMA_BUILD=ON option. You have several ways of doing so:

1. Run two different colcon build commands.

   colcon build --packages-up-to fastrtps --cmake-args -DSECURITY=ON -DEPROSIMA_BUILD=ON -DCMAKE_BUILD_TYPE=Debug --parallel-workers 32
   source install/setup.bash
   colcon build --packages-select ShapesDemo --cmake-args -DCMAKE_BUILD_TYPE=Debug --parallel-workers 32
   

2. Use a .meta file for defining compiling options with colon (see an example here).
3. Build ShapesDemo in a different colcon workspace from the rest, and source the other one before running colcon build on the ShapesDemo one.

Hi @stilong,

I'm going to combine answers for this ticket and also for its duplicate in Fast DDS (eProsima/Fast-DDS#3322).

I have submitted to remove the residual CMake code that causing the compilation error.
Looking at the other issue, it seems that you are trying to compile not only ShapesDemo, but test for all the workspace (hinted by -DEPROSIMA_BUILD=ON); if that is not the case, you may consider using a colcon .meta file to specify different build options for the different packages in the workspace.

In any case, to compile Fast DDS linking it against its submodule dependencies (TinyXML2 in this case), the appropriate flag is -DTHIRDPARTY=FORCE (see here).

I have prepared a Dockerfile to showcase the entire installation on a clean Ubuntu 22.04. Mind that your issue points to Ubuntu 20.04; I choose 22.04 since installing Qt was actually not the point of the issue, and installing Qt it's easier in 22.04.
