Error while compiling rails app

[novneetnov]

I am using ruby 2.3.3 with Rails 5.0.4
While trying to compile a rails app with ./rubyc bin/rails I ran into an error:

In file included from ./curses.priv.h:325:0,
                 from ../ncurses/lib_gen.c:19:

And the the output executable binary file was not created. Any light on this?

Interesting. This is due to a dependency-library failing to compile, i.e. ncurses. What is your compiler version? Maybe it's too old? You could Google it since this is about ncurses and not related directly to ruby or rubyc.

[novneetnov]

Yeah. You are correct. This was an external error, which I seem to have fixed. But I have run into another error.

I have bundler version 1.15.3. Do I need to downgrade it to v 1.15.2?
Oh and you have not mentioned it the docs, but rubyc works fine with rvm right?

[pmq20]

@novneetnov This is definitely my fault, since there is another similarly reported issue . Let me fix it ASAP.

#11

[pmq20]

@novneetnov Weird. I failed to reproduce it locally in the latest master branch (i.e. 0.4.0). Which version of rubyc are you using?

[novneetnov]

@pmq20 I have downloaded rubyc by the following command:
curl -L http://enclose.io/rubyc/rubyc-linux-x64.gz | gunzip > rubyc
This get me the 0.3.0 version.
How do I get the latest version? Should I clone the master branch locally?

[pmq20]

@novneetnov Yes, please clone the master branch and then execute from bin/rubyc to see if it is already fixed. I'll release the next version very soon. Thanks!

[pmq20]

I figured it out. gem cannot read a virtual path. The reason why it works from the master repo is that it is reading a real path. When running from stand-alone nodec or nodec.exe, it is a virtual path.

Fixed in a84edb6

I'll release it in rubyc v0.4.0 as soon as possible.

[obromios]

I have the same problem, look forward to rubyc v0.4.0

[pmq20]

@novneetnov @obromios Ruby Compiler v0.4.0 released! Download: http://enclose.io/rubyc

[obromios]

I downloaded the latest version and checked that ./rubyc --version gives 0.4.0. I am no longer getting the error above, but I get a few problems. I am running on a Mac.

The first is a warning 'The latest bundler is 1.15.4, but you are currently running 1.15.3'. This is puzzling because I am using 1.15.4, and do not have 1.15.3 installed. As well, in the output of the rubyc it actually says it is installing 1.15.3.

Second, there appears to be a fatal error 'Your Ruby version is 2.4.1, but your Gemfile specified 2.2.7
Failed Running...'
Do I need to upgrade to ruby 2.4.1 to use rubyc?

As a sanity check, I ran rubyc on a 'hello world' ruby file.

#!/usr/bin/env ruby
puts 'Hello World'

This also failed, with the error

[pmq20]

@obromios Regarding the sanity check, it looks as though enclose_io_memfs.squashfs does not exist. Could you paste more log so that I can inspect about the generating of enclose_io_memfs.squashfs?

[drbrain]

Closing due to lack of response.
