G++: fatal error: Killed signal terminated program cc1plus

Beginners

I have a checkout of an llvm-project fork, and I’ve followed these steps:

$ cmake -S llvm -B build-release-ninja -G Ninja -DCMAKE_C_COMPILER=gcc -DCMAKE_CXX_COMPILER=g++ -DCMAKE_BUILD_TYPE=Release -DLLVM_ENABLE_ASSERTIONS=On -DLLVM_PARALLEL_LINK_JOBS=10
$ ninja -C build-release-ninja check-llvm

I get these errors:

g++: fatal error: Killed signal terminated program cc1plus
compilation terminated.

I’ve also tried with cc before gcc.

Is this maybe also to do with machine resources?

Thanks!

  • Try more light optimizations. -DCMAKE_BUILD_TYPE=MinSizeRel
  • Reduce parallelism with smaller ninja -jN. N is (NumberOfCores+2) by default.
  • Retry problematic compilations manually :slight_smile: ninja lib/IR/CMakeFiles/LLVMCore.dir/Verifier.cpp.o is available. (Or try ninja multiple times)

How is your buildhost? Cores and RAM amount.

You can check sudo dmesg to see if g++ is being killed by the OOM killer. cc and c++ are probably just gcc and g++ since you’re on Linux. You should try compiling with Clang instead, if you want to reduce memory usage.

Thanks for the help @chapuni.

12th Gen Intel(R) Core™ i7-1265U 1.80 GHz.
cat /proc/cpuinfo shows 12 processors.
And 16 GB RAM.

Thanks for the help @overmighty.

I’m trying with this now:

cmake -S llvm -B build-ninja-minsizerel-clang -G Ninja -DCMAKE_C_COMPILER=clang -DCMAKE_CXX_COMPILER=clang++ -DCMAKE_BUILD_TYPE=MinSizeRel -DLLVM_ENABLE_ASSERTIONS=On -DLLVM_PARALLEL_LINK_JOBS=10

ninja -j10 -C build-ninja-minsizerel-clang check-llvm

The last two commands I posted ran fine in my mini PC:

  • 16 AMD Ryzen 7 5700G processors 3.80 GHz.
  • 32 GB RAM.
