Hello,

The build fails after reporting that the “llvm/ExecutionEngine/Orc/LazyEmittingLayer.h” missing, at commit 0a5f35b6d9544122d7ab0498c0892cd29c734506.

```julia

In file included from /home/sanjay/Software/polly_julia/julia_src/src/codegen.cpp:117:0:

 #include "llvm/ExecutionEngine/Orc/ObjectLinkingLayer.h"
                                                         ^
compilation terminated.
make[1]: *** [codegen.o] Error 1
make: *** [julia-src-release] Error 2

```

A `find . -name ObjectLinkingLayer.h` on julia\_src, julia\_build, the llvm source and build directories didn’t return any results.

How can I resolve this ?

Thank You,  
Sanjay

Fixed by [https://github.com/JuliaLang/julia/pull/20823](https://github.com/JuliaLang/julia/pull/20823), dup of [Build Error on Linux : template errors on commit 00b7b606d82c36461d448a2a7b59475235199acf](https://discourse.julialang.org/t/build-error-on-linux-template-errors-on-commit-00b7b606d82c36461d448a2a7b59475235199acf/2278), no need to post the same issue twice since both are llvm compile error with svn builds.

Hello yuyichao,

Thanks for fixing it !

I’m new to Julia’s ecosystem and the technical jargons. Could you please clarify the following ?

- What is an `svn build` ? Is it different from a `git build` ( if there is one ) ?
- How is this bug related to the one reported in the duplicate question [here](https://discourse.julialang.org/t/build-error-on-linux-template-errors-on-commit-00b7b606d82c36461d448a2a7b59475235199acf/2278) ?

Thank You,  
Sanjay

You are building llvm svn, not 3.9.1, (or more accurately, with polly enabled)

Explained [here](https://discourse.julialang.org/t/build-error-on-linux-template-errors-on-commit-00b7b606d82c36461d448a2a7b59475235199acf/2278/7)

i.e. building the files at the HEAD commit of master w.r.t. git ( latest version ) ?

Of LLVM, yes.
