[umtclskn]

Hi all,

I could not compile the px4_fmu-v5_rtps with master and v1.13.0.rc1. But there is no compile error with v1.12.3 version.

My Environment: Ubuntu 18.04 FastDDS 2.0.2 Gradle 6.4 foonathan_memory_vendor openjdk 11.0.15

I got this error:

Why these versions does not compile?

Thanks.
