Can you help me out with this? Thanks in advance!

Hi Lorenzo,
thanks for the report. It looks like that I put the wrong example into the folder. The example uses more features than implemented in chapter 5. I need to check this.

Ok thanks, I'll stand by. Meanwhile I share with you that, removing the lines from:

Learn-LLVM-12/Chapter05/tinylang/tools/driver/Driver.cpp

Line 142 in e53e4ce

if (codegen::getMCPU() == "help" ||

to:

Learn-LLVM-12/Chapter05/tinylang/tools/driver/Driver.cpp

Line 163 in e53e4ce

}

seems to work correctly

Any news?
