Mac OS intallation problem

Hi, I'm currently on MacBook Pro with MacOS BigSur, and I did Conda install wget and cmake, however, I have another error.

"vtable for llvm::raw_string_ostream", referenced from:
TVM::codegen::LLVMModuleNode::GetSource(std::__1::basic_string<char, std::__1::char_traits, std::__1::allocator > const&) in llvm_module.o
NOTE: a missing vtable usually means the first non-inline virtual member function has no definition.
ld: symbol(s) not found for architecture arm64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
make[1]: *** [lib/libhcl.dylib] Error 1
make: *** [build-tvm] Error 2

Are you using your own LLVM or you are using the LLVM installed by HeteroCL?

[seanlatias]

Can you also try to install from source?

[melodylylin]

I’m not quite sure, but I think I’m using the one installed by HeteroCL, is there anywhere to check?

[melodylylin]

I tried to redo the install from source again, and also edit the LLVM config, to let it use the version that is installed by HeteroCL, still have the same error.

[seanlatias]

Hmmm... Because from the error message it's related to LLVM. Do you have a more complete error message?

[seanlatias]

Can you also describe how you install from source? You just need to clone the repo and run make. No other things need to be done.

[seanlatias]

One thing you can also try is to install g++. Mac uses clang by default. And when running make, set the CXX variable by using make CXX=/path/to/g++.

Hi, so I just tried on the MacBook Pro 16 inches with intel chip and same OS system, it works fine. I guess it's the M1 chip problem on MacBook Pro 13 inches.
