Description

sentry-native crashpad build fails on Linux arm64

/tmp/ccxvkBk7.s: Assembler messages:
/tmp/ccxvkBk7.s:27: Error: selected processor does not support `xpaclri'
make[2]: *** [crashpad_build/util/CMakeFiles/crashpad_util.dir/build.make:930: crashpad_build/util/CMakeFiles/crashpad_util.dir/linux/pac_helper.cc.o] Error 1

When does the problem happen

  • During build
  • During run-time
  • When capturing a hard crash

Environment

  • OS: Linux 5.10.104-tegra aarch64
  • Compiler: g++ (Ubuntu 9.4.0-1ubuntu1~20.04.2) 9.4.0
  • CMake version and config: 3.30.2

Steps To Reproduce

cmake -B build -DCMAKE_BUILD_TYPE=RelWithDebInfo -DSENTRY_BACKEND=crashpad
cmake --build build --parallel
