Building static_h on x86_64

[guest271314]

Hermes git revision (if applicable):
React Native version:
OS: x86_64

Steps To Reproduce

I have tried to build the static_h branch twice. Following instructions here https://medium.com/@gautam1168/compiling-typescript-to-native-code-0238d69ca582

mkdir hermes_workspace
cd hermes_workspace
git clone git@github.com:facebook/hermes.git
cd hermes
git checkout static_h
cd ..

Each occasion the system has frozen.

Hi, you haven't provided any information about your system - what OS, how much RAM, which command is freezing, etc.

Generally speaking, our build process has no power to freeze the OS, we are just running the compiler and linker in a standard way.

If you build environment is configured with too little RAM and a lot of cores, it is possible that Ninja is starting too many instances of Clang, consuming too much RAM and the system is thrashing, making it appear frozen. The solution would be to decrease the number of Ninja processes by building with ninja -j2 shermes, for example.

Unfortunately the Hermes team can't really provide support about the configuration of dev environment, but it is possible that members of the community can, so I am transferring this issue to discussions.
