我正在尝试使用clang(3.7.0)在运行linux mint的笔记本电脑上设置一个OpenMP项目.
现在我已经读过OpenMP不会立即得到支持所以我按照本教程https://clang-omp.github.io/将openMP集成到了clang中.
我已经克隆了源代码,设置了环境变量并将-fopenmp标志设置为我的项目,但是在构建时我仍然收到错误"致命错误:'omp.h'文件未找到".
我的猜测是我设置了环境变量错误.有没有办法检查我是否把它们放在正确的位置？我刚刚将它们复制到.bashrc文件中.
编辑:当我运行$ locate omp.h时,我得到:

但是,当我单击"确认"以进行安装时,我收到以下错误
Unable to read repository at http://petrituononen.com/llvm4eclipsecdt/update.
http://petrituononen.com/llvm4eclipsecdt/update is not a valid repository location.
这个网站似乎已经关闭,但我找不到任何其他来源.
有没有办法让Clang在Eclipse Mars上工作？
我是 Ruby on Rails ans 的新手，所以我正在学习 Rails 4 敏捷 Web 开发教程。所以用户可以登录，为此我在文件 user.rb 中使用了 has_secure_password：
class User < ActiveRecord::Base
has_secure_password
validates :name, presence: true, uniqueness: true
end
但是当我运行服务器时，我收到错误：
cannot load such file -- 2.0/bcrypt_ext
这是应用程序跟踪
app/models/user.rb:2:in `<class:User>'
app/models/user.rb:1:in `<top (required)>'
app/controllers/users_controller.rb:7:in `index'
This error occurred while loading the following files:
bcrypt
bcrypt_ext
2.0/bcrypt_ext
我在 gemfile 中包含 gem 'bcrypt-ruby', '~> 3.0.0' 但它仍然不起作用。
我在类似的问题中读到它与“捆绑安装”有关，但我无法解决问题。
