I had the same problem.
Have you solved this problem?

I'm facing the same problem.
Please answer this.

I solved this problem by adding -DCMAKE_BUILD_TYPE=Release and -DLLVM_USE_LINKER=gold cmake options as described here. My final build commands looks like:

git clone https://github.com/llvm/llvm-project.git
cd llvm-project
mkdir build && cd build
cmake -G Ninja ../llvm -DLLVM_ENABLE_PROJECTS="clang;clang-tools-extra" -DLLVM_USE_LINKER=gold -DCMAKE_BUILD_TYPE=Release
ninja

I also encountered this problem. I solved this problem by adjusting the memory of the virtual machine. In my compilation, this libLTO.so will occupy at least 7 g of memory when linking, and will fail if it is not enough. So please check your memory situation.

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 :

This one works for me. The default memory setting for my virtual machine is 4GB. It worked after I increased the memory size to 16GB.

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

This worked.

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...

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.
