Build Error On Window

[pravin-d]

I'm trying to install Canvas LMS using the following guide https://github.com/instructure/canvas-lms/wiki/Quick-Start

This has a dependency on i18nema -v 0.0.7 I'm getting the following error

i18nema.o: In function load_yml_string': ~\Ruby193\lib\ruby\gems\1.9.1\gems\i18nema-0.0.7\ext\i18n ema/i18nema.c:429: undefined reference tosyck_new_parser' I guess the deps for i18nema does not include syck. Also syck-1.0.1.gem requires Ruby >=2.0.0 (Canvas is req Ruby 1.9.3).

PS Maybe i18nema-0.0.7 should define its deps to a proper version of syck

syck is already included in ruby 1.9.3 and below, so i18nema ought to be able to use it. i'll investigate a bit and see what i can find out

in the meantime, you could remove i18nema from your dependencies. canvas can work fine without it (albeit slightly slower). in addition to removing it from the gemfile, you'll need to change the following section of config/initializers/i18n.rb from

I18n.backend = I18nema::Backend.new
I18nema::Backend.send(:include, I18n::Backend::Fallbacks)
I18n.backend.init_translations

to something like:

I18n.backend.send(:include, I18n::Backend::Fallbacks)

as a side note, canvas isn't supported on windows, so once you get past this obstacle, i would not be surprised if you encountered several more.

Thank you u for the reply. I checked. Ruby 1.9.3 does have syck.so. Path to the .so is Ruby193\lib\ruby\1.9.1\i386-mingw32\

The .so is not found or something I guess.

Here's what I'm getting:
