LLC Compiler is not recognized as the name of a cmdlet, function, script file, or operable program

Question

Im creating a custom programming language using python, PLY as lexer and parser, and LLVMlite as low level intermediate language to do code generation. I have installed PLY and LLC using Python pip

I use LLC to create a object file output.o, and GCC to create the final executable file as follows.

$ llc -filetype=obj output.ll
$ gcc output.o -o output

When im executing llc -filetype=obj output.ll i get

llc : The term 'llc' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included,  
verify that the path is correct and try again.
At line:1 char:1
+ llc -filetype=obj output.ll
    + CategoryInfo          : ObjectNotFound: (llc:String) [], CommandNotFoundException
    + FullyQualifiedErrorId : CommandNotFoundException

I have spent hours on this but cant figure out. What is wrong?

Answer 1

The PyPi package llc has nothing to do with LLVM's llc tool. You can't install the latter via pip because it's not a Python package. You need to install the LLVM tools to get it.
