Hello guys
first of all sorry for my bad english.

i wanted to execute the “bundle install” command (Number 7 in the installation guide https://community.openproject.org/projects/openproject/wiki/Installation_Ubuntu ) but i get the same error message everytime:

Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension.

An error occurred while installing binding_of_caller (0.7.2), and Bundler cannot
continue.
Make sure that `gem install binding_of_caller -v ‘0.7.2’` succeeds before
bundling.

Can someone help me?

Hi Christian

the file vm_core.h should be in

root@1a748e650296:/# find / -name "vm_core.h"
/home/openproject/.rvm/src/ruby-2.1.0/vm_core.h
/home/openproject/.rvm/gems/ruby-2.1.0/gems/binding_of_caller-0.7.2/ext/binding_of_caller/ruby_headers/192/vm_core.h
/home/openproject/.rvm/gems/ruby-2.1.0/gems/binding_of_caller-0.7.2/ext/binding_of_caller/ruby_headers/193/vm_core.h

check your install of ruby

cheers
Brendan

Hi Christian,

you are using ruby 1.8 which is not supported by OP 3.0/4.0. Please install ruby 2.1 (e.g. via RVM or rbenv) and this and other problems should disappear.

Regards

Jens
