My system got hanged during Ninja compilation.
Is there any system requirement for LLVM/CLANG/Ninja ?

My configuration is Ubuntu 16.0x ,12GB RAM and 27GB swap memory.

Hi Srinivas,

Which parameters did you give to cmake?
Can you show the output of pwd and ls -l ?

I get the exact same error, because I choose ninja as the cmake generator.

$ ninja check-llvm-unit
$ ninja check-llvm
$ ninja check-all

all work for me.

Csaba

Can you please let me know the problem.Is there any configuration or setup is missing.
