Error while building AirSim

[huytd-pi]

Bug report

• AirSim Version/#commit: v1.7.0
• UE/Unity version: 4.25
• autopilot version: PX4
• OS Version:Ubuntu 18.04

I do AirSim build on linux, processes I follow steps like this path: https://microsoft.github.io/AirSim/build_linux/ I followed the steps one by one until the AirSim build step got an error. Every time I run the build, there is a different message like: _make: [cmTC9d0d3/fast] Error 2 _make: [cmTCfb769/fast] Error 2

Hi and welcome @huytd-pi! See if this post can help you.

Hello @huytd-pi! I just met the same problem as you. I thought that clang compiler didn't work well in our environment (I don't have any idea about the specific reason..) Anyway, so I changed the compiler as gcc using ./build.sh --gcc and it works.

I hope you can fix your problem as well. Thanks.

@jclee0109 Thanks alot -gcc resolved the issue
