Installation problem

[Leo1726]

I followed the instruction from http://heterocl.csl.cornell.edu/doc/install_from_src.html During the build process, I got the following error:

../heterocl/tvm/dmlc-core/include/dmlc/./parameter.h:997:25: warning: catching polymorphic type ‘const class std::out_of_range’ by value [-Wcatch-value=]

Which LLVM version is that?

[Leo1726]

Which LLVM version is that?

8.0.0svn (a special svn version)

[seanlatias]

Can you try 6.0?

[seanlatias]

Or you need to upgrade it to 9.0 I believe.

OK, I would have a try, thanks.

[Leo1726]

I built llvm 6.0 and set its llvm-config path in HCL's Makefile.config. It works. I guess llvm8.0svn is not compatible.

As we have released a new version of HeteroCL that entirely moves the compilation stack to MLIR, issues related to the original HalideIR flow will be closed. Please feel free to check out the latest HeteroCL and see if it works.
