Hi all, today I just fetched the latest 3.5.4 to my repo and pulled it onto my local disk. Then I configured waf with board px4-v2 and started building the latest arducopter using “./waf copter”, however, the build failed and the error message is as follows:
Build failed

When I tried to build only example sketches, similar problem occurs only with “objs/AP_Mission/UNKNOWN” and with the file AP_Mission.cpp.
The problem never occurred when I was using 3.5.3, and when I updated to 3.5.4, there was no serious conflict----only a merge conflict upon an example sketch occurred which I resolved by changing back the values.
