I am doing : cmake -DLLVM_ENABLE_PROJECTS=clang -DLLVM_USE_LINKER=gold -DCMAKE_BUILD_TYPE=Release -G "Unix Makefiles" ../
I am getting this error:

Just hit the same on Debian bullseye with 32gb of memory.

This worked.

HI Devyani,

Have you resolved this problem ?
I am facing same issue.

Thanks, -DLLVM_USE_LINKER=gold -DCMAKE_BUILD_TYPE=Release fixed this on my MacBook M1 (16GB). I even had problems on my 8 Core Xeon with 64GB RAM, that's quite insane...

Hello,

Not sure if somebody could help here on priority !
I am unable to build the LLVm 10.0.0 with GCC 9.3.0 version.
On running or executing the "make -j6" command it throws an error at 24%
The last few errors are pasted as below :

It is UNBELIEVABLE that clang / ld.gold would take THAT much memory just to link. 7GB is an OUTRAGOUSLY large amount of memory for something like this.
