I have pulled the git repo and I’m trying to compile v1.7.3, but the process stalls here:

```julia
Sysimage built. Summary:
Total ─────── 53.120629 seconds 
Base: ─────── 22.231496 seconds 41.851%
Stdlibs: ──── 30.887624 seconds 58.1462%
    JULIA usr/lib/julia/sys-o.a
Generating REPL precompile statements... 25/36

```

Then nothing happens. Any idea what could be going wrong?

Here’s the trace after ^C:

Update 1: No special flags, just ran “make clean” and “make”.

Update 2: I’m not a pro programmer, I never program in C, so there should be unusual env settings:

Are you using any specific compilers ?  
Are you using any specific make flags ?

This path looks suspicious `/workspace/srcdir/libuv/src/unix/epoll.c` vs your sources located in `/home/dabrowsa/lang/julia/julia/src`: julia should build `libuv` (see `deps/libuv.mk`, `deps/libuv.version`) along all deps.

My build of `1.7.3` on `22.04` requires at least this PR [https://github.com/JuliaLang/julia/pull/45649](https://github.com/JuliaLang/julia/pull/45649) for the tests to pass (see [Build: failing `Float16` `intrinsics` on `1.6.6` or `1.7.2` on `ubuntu 22.04` · Issue #45433 · JuliaLang/julia · GitHub](https://github.com/JuliaLang/julia/issues/45433)).

The Makefile has this:

`JL_PRIVATE_LIBS-$(USE_SYSTEM_LIBUV) += libuv`

Should I change something here?

</div>

`USE_SYSTEM_LIBUV` default to 0 ( see [julia/Make.inc at dbae5a50e506f05a4d4f2f3471c76291e5252df4 · JuliaLang/julia · GitHub](https://github.com/JuliaLang/julia/blob/dbae5a50e506f05a4d4f2f3471c76291e5252df4/Make.inc#L58)), so normally no.

We need more information on how you build julia. Try to inspect you environment variables for potential conflicts.

EDIT 1: `LD_LIBRARY_PATH=:/usr/lib/llvm` this is likely to conflict with the llvm build of julia.

EDIT 2: `WARNING: Error during initialization of module LinearAlgebra:` this is not what I’d call `succeed` 🙂 .

I think @jling was implicitly asking: _why bother compiling julia, as the recommended way of obtaining julia is to use official binaries available at [Download Julia](https://julialang.org/downloads/) ?_

yes, it is, but why are YOU compiling it instead of get 1.7.3 from download page?

Oh, that’s news to me, I’ve been following Julia for about 10 years and it’s always been recommended to compile it yourself.

no f way… [Create getting-started.md · JuliaLang/www.julialang.org@b2e11b5 · GitHub](https://github.com/JuliaLang/www.julialang.org/commit/b2e11b5fecb01cf5bfde299ece107e66eaf9b487)

it has been at least 3 years and I suspect it’s much longer than that since people recommend download official binary no matter what
