How to fix error that occurred while building CXX object CMakeFiles/tvm_objs.dir/src/target/llvm/codegen_llvm.cc.o?

Question

I've built LLVM from source following these instructions and now I am attempting to build TVM from source according to the instructions in this official website

I do the cmake3 -DCMAKE_C_COMPILER=gcc -DCMAKE_CXX_COMPILER=g++ .. command and get the following output

But when I run make -j24 I get the following output:

How do I fix this?

In the first place, avoid building from source where possible. LLVM, at least, is available in pre-built packages for many of the more popular operating systems. — John Bollinger, Oct 11 '20 at 12:45
The error appears to indicate a source-code incompatibility between the version of TVM you are building and the version of LLVM you are building it against. In that case, you would need to figure out from TVM documentation and / or from relative TVM and LLVM release dates which versions work together. You might also find more information on TVM's issue tracker and / or project discussion forums. — John Bollinger, Oct 11 '20 at 12:49
@JohnBollinger Thanks. I'm taking your advice and am now trying to get the binary of LLVM from here (https://releases.llvm.org/download.html) but my linux is Cent OS 7 with the architecture x86_64 and I can't find the appropriate version for this architecture. — Jang Hyeon Choi, Oct 11 '20 at 13:47
I acknowledge that I said "in the first place", but that was meant as a *logical* first, not a "do this first". It is not useful to look for a pre-built package before you have an idea of which version you need. And if you cannot avoid building LLVM for your particular target platform then so be it. For the record, though, do look first at the packages provided by your operating system. CentOS 7 does not offer LLVM packages, but CentOS 8 does (these are of course unusable for you; it's just an observation). — John Bollinger, Oct 11 '20 at 13:58
