[llvm-dev] error in building llvm with default options

Tue Jan 7 22:31:54 PST 2020

Hello,

I tried to build the llvm with debug (default) type with many cmake
options, such as

1. -DLLVM_ENABLE_LLD=True

2. BUILD_SHARED_LIBS

3. -DLLVM_PARALLEL_LINK_JOBS=1

and many more but no luck.

Finally, I am able to successfully build the llvm with default cmake
options in a system with 64GB RAM and 32 core processor.

But, these default options should change such that one will be able to
build at least in a system with 8/16GB RAM. Otherwise, it is very difficult
to build the debug type.

Thank you all for your help.

Priyanka
