I would prefer the use of rebar3 in this project, definitely not mix since that creates an unnecessary dependency to Elixir. It should be trivial to use rebar3 for this. Using rebar3 would also get reid of the dependency to 7z that came up when I tried to 'make escript'.

hello all,
I also hit this problem, and renaming the parent dir was the ultimate solution. Strangely enough if I used zip and not 7z to create the escript (ESCRIPT_ZIP env var) it worked so I thought initially it's an OS X/7z issue.
Anyway I just introduced erlang.mk because the project already used custom make rules, and I've never used erlang.mk before, so it was a good chance to try - rather subjective choice. So I have no objection in converting to rebar3.
(To be fair you can look at the erlang.mk file is just a blackbox library, peeking into rebar3 itself could be just as hairy)

It sounds like we have a consensus to start to use rebar3 and I don't have any objection to that. Is anyone willing to submit a PR?

Actually as Gradualizer has no dependencies it should already work perfectly with rebar3 too (without a rebar.config).
So if you are on windows and you don't have make, but you have rebar3, you can just use it
rebar3 compile
rebar3 escriptize
rebar3 eunit
Also this is why Gradualizer works perfectly as a rebar3 dependency/plugin.
But I am absolutely not against converting to rebar3 "officially", this mostly consists of updating the README (and removing the huge erlang.mk file)
One con of erlang.mk is that I dont think it supports creating a hex package.

Perhaps switching to rebar3 (or even Elixir's mix, which works quite well for erlang projects as well) would be better?

Been following the makefile at:
https://github.com/josefs/Gradualizer/blob/master/erlang.mk#L2634
And I ran across something interesting. It is going UP out of the directory, then trying to pack gradualizer as per the line at: https://github.com/josefs/Gradualizer/blob/master/Makefile#L29
PROJECT = gradualizerHowever, this git repository is named Gradualizer, thus meaning it clones out as Gradualizer, and not gradualizer.
Now, renaming the directory as gradualizer (which does not follow the naming conventions of this repository) gets it to compile:

--stop-on-first-error stop type checking at the first error

So immediately that means that the erlang.mk file at https://github.com/josefs/Gradualizer/blob/master/erlang.mk is broken because it absolutely should not ever be stepping outside of the repository directory, but a greater question is how does it work for anyone else with a default clone when the repository name is Gradualizer since the clone uri is https://github.com/josefs/Gradualizer.git thus defaulting the directory name to be Gradualizer...

@OvermindDL1 I got it to work by changing the name of the directory too. I agree that it's a strange way of doing it.
Deciding on a build system is often controversial. What we have now seems to work decently so I don't think people are too keen of changing unless there is a real benefit.

Yeah I don't really care what's used as long as it works. Although that erlang.mk file is rather hairy and that is definitely a bug regardless that will break the ability to, for example, use this repository as a dependency for, say, an Elixir Gradualizer mix integrator.

Actually I don't think this repo could be used like that anyway as make does not come on Windows so I don't think erlang.mk could be the build system anyway, hmm...
Well, a rebar3 or a mix version of the build system would be just a couple of lines as it stands (unlike the rather huge erlang.mk file...), it's fairly simple to compile as-is.

The problem concerns only when used as a dependency for another project, right?
It should definitely be possible to use this repo as a dependency for projects using rebar3. Do we even need a rebar config file to make it work? I guess it works already, but if not, we should add a small rebar config file. Has anyone tried?
It would be nice however if the Makefile would work as well, when used as a dependency for projects using the erlang.mk dependency way (i.e. download the dependency and run make inside). If possible, it would be nice to not require a dependency to rebar in this case. A simple rule just running erlc would be enough for this.
Regardless of build system, how about renaming the repo to lowercase gradualizer? It doesn't hurt that the repo has the same name as the application.
When not used as a dependency, I don't mind using rebar, but I think the make file works fine as it is for this.

No, it happens when you try to build it straight from a fresh git clone into the default named directory on any filesystem that is case-sensitive.
Using something like rebar3 'would' make it significantly easier to distribute this via packaging systems like hex as well as using it as a dependency to integrate it into build tools, but that's just a bonus around the overall issue.
If possible, it would be nice to not require a dependency to rebar in this case.
As I recall you can include a rebar thunk/wrapper file to just download-and-run, but in general if someone is doing some BEAM language work (erlang/elixir/lfe/alpaca/whatever) then they probably have rebar anyway (and considering windows as well they more likely have rebar3 than make regardless).
Regardless of build system, how about renaming the repo to lowercase gradualizer? It doesn't hurt that the repo has the same name as the application.
This would be an immediate fix and I'm all for it, regardless the erlang.mk file is bugged anyway, but that would at least make clone-and-compile work.
When not used as a dependency, I don't mind using rebar, but I think the make file works fine as it is for this.
It still prevents windows users from compiling it. Multi-platform is important.

One con of erlang.mk is that I dont think it supports creating a hex package.
It doesn't? That seems odd considering how well hex dependencies are used in the BEAM world across a variety of languages now. Rebar3 has native support so that would be a definite boon.
