Hi osquery team, does osquery building depends on clang? i am suffering from this err when i am building osquery [ 65%] Building CXX object libs/src/aws-sdk-cpp/CMakeFiles/thirdparty_aws-cpp-sdk-ec2.dir/src/aws-sdk-cpp/aws-cpp-sdk-ec2/source/model/CreateTransitGatewayRouteRequest.cpp.o clang-9: error: unable to execute command: Killed clang-9: error: clang frontend command failed due to signal (use -v to see invocation) clang version 9.0.1 ( c1a0a213378a458fbea1a5c77b315c7dce08fd05) Target: x86_64-osquery-linux-gnu Thread model: posix InstalledDir: /tmp/osquery-toolchain/usr/bin clang-9: note: diagnostic msg: PLEASE submit a bug report to and include the crash backtrace, preprocessed source, and associated run script.

It does use clang, which is the toolchain the instructions in the wiki tells you to download; the errors you’re seeing happens when the compiler doesn’t have enough memory. Unfortunately the AWS SDK has a very big C++ file (EC2Client.cpp) which requires around 8GB of RAM to build
A rough measure of how much memory one requires to build osquery is a base of 8GB + 0.5GB per each parallel job
