Cant install / compile comeonin on Core2Duo

Questions / Help

I tried to install this dependency called “comeonin” on MacOS Sierra and also on Linux but failed to compile. Both computers have a Core2Duo processor.
I’m using latest Elixir and Erlang

could not compile dependency :comeonin, “mix compile” failed. "

I followed these instructions and tried to add the following lines to Makefile but I dont know if I did it correctly:

added: -arch i386 -arch x86_64 to both CFLAGS and LDFLAGS in Makefile

First I added both of those options on the first line on CFLAGS
I dont really know C programming, so I created a LDFLAGS with those options, then I edited the LDFLAGS inside the if statement and did some more combinatinos but still doesnt compile.

Please help!

tryxcode-select --install in terminal.app to ensure you have the dev commandline tools installed…

I would not change the makefile, it should work if you have gcc etc installed…

this might also help:

For most plugins, it is good if you have installed the following packages OR their equivalent on your OS
macOS: Install these via homebrew coreutils automake autoconf openssl libyaml readline libxslt libtool unixodbc
Ubuntu: automake autoconf libreadline-dev libncurses-dev libssl-dev libyaml-dev libxslt-dev libffi-dev libtool unixodbc-dev
Fedora: automake autoconf readline-devel ncurses-devel openssl-devel libyaml-devel libxslt-devel libffi-devel libtool unixODBC-devel

thank you for answering!
When I tried to install comeonin, the latest (6/12/2017) xcode developer tools was installed as I had downloaded the latest version from Apple (without xcode app) and also coreutils were installed. I also installed now the brew version but it still does not compile.

I installed asdf and I’m not sure if I’m supposed to use it to download a precompiled binary of the lib I need, as I did not find any precompiled comeonin binary.

sorry asdf not needed for this, just where I got that instructions for packages from…

make sure you have atleast coreutils automake autoconf installed with brew…

can you run make --debug=v inside the deps/comeonin folder?

it’s one of those where it just works for the rest of us(as the packages are already installed)… but I’m not certain which packages is required…

Thank you. Your advice helped me to find out that I needed to install/compile sub-dependencies. And it was possible to get comeonin to work on Linux.

On OSX I stil get the error:
/bin/sh: 0.59.0: No such file or directory
make: *** [Makefile:27: priv/bcrypt_nif.so] Error 1

The command “make --debug=v” now displays:

** (Mix) Can’t continue due to errors on dependencies

I tried the advice from here but it didnt work. I tried to export shell, to create symbolic links, etc.
Cant I just hardcode that shell into makefile ?
