Has anyone tried to build the Julia 0.6 executable from the source code? I’m trying to do so in a Docker container and running `make` (or `sudo make`) produces \>100 errors. Any advice would be very appreciated!

This Dockerfile works for me. You probably want more packages for doing any real work but this is enough to build Julia.

```julia
FROM ubuntu:16.04

RUN apt-get update \
 && apt-get install -y build-essential cmake curl gfortran git m4 python

RUN cd /opt \
 && git clone https://github.com/JuliaLang/julia.git \
 && cd julia \
 && make -j8

```

It works for me as well - I didn’t use a dockerfile. Here are the packages I needed to install:

gcc, cmake, gfortran, g++, xz-utils, python, bzip2, m4

Thank you for your responses! So I have all of the above packages. Running `make -j8` seems to finish but no executable is produced. Is there something obvious that I’m missing here??

From the root of the source directory, it’s in `usr/bin/julia`, and there should be a symlink from the root.

Right, there’s no executable in `usr/bin/`. The directory is created during the make but then is empty. Once the make finishes, I get the (very descriptive) message `make: *** [julia-deps] Error 2` but that’s the only red flag I see…

That error is a fatal error. Look several lines above it for the reason it happened. (Likely a missing dependency.)

Also - when you run into errors like this, it’s best to build serially (that is, without `-j`) while you troubleshoot. Sometimes race conditions (that won’t exist in a serial build) are the cause of build failures.

Found the dependency issues! `apt-get` wasn’t updating my version of cmake which caused the other issues. Got it to work once I cleaned the OpenBlas build, reinstalled the julia dependencies and then ran the julia `download_cmake.sh` script. Thank you for your help!
