我正在尝试使用GMP库为加密部署Ruby on Rails应用程序。一切都在发展中很好。
当我git推送到Heroku或者Openshift时，我得到的错误信息是：
remote: Installing gmp (0.5.47) with native extensions .........
remote:
remote: Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension.

事实证明，Heroku支持承认他们的堆栈图像尚未包含GMP。 他们建议我编写自己的buildpack以在生产服务器上包含GMP库。 看完custom buildpack for OpennSSL here之后我也不知道了。 欢迎任何建议。
