Hi there, I am encountering a single issue within DDS-Router build for WINDOW-10 OS version. The compiling process succeed but one module failed to get build within multiple modules, that "ddsrouter-yaml-validator" sems to failed as following log depict:

Can anyone give a clue what is missing from the build?

Your reply is greatly appreciated.

Hi @iekhanx

Some points:

• It seems like you are using an old version of CMake. I strongly suggest to update to a 3.x version
• The error you are encountering is that yaml-cpp is not well installed or it is not found from colcon to build the forward packages.
  • Check our documentation on how to install yaml-cpp for windows using CMake: https://eprosima-dds-router.readthedocs.io/en/latest/rst/developer_manual/installation/sources/windows.html#yaml-cpp
  • use colcon argument --event-handlers console_direct+ in order to see the logs of the compilation. With that, you could check if the library is being installed correctly and if the installed files are in the PATH to compile the ddsrouter_yaml.

Colcon it is not so stable for Windows, my suggestion is to install yaml-cpp in an aside workspace (using CMake for example) and then adding it to the path when compiling the rest of the library
