ruby-on-rails - 在RVM中的Mac OS X 10.9上安装ruby-odbc gem

Question

我正在尝试在ruby-1.9.3-p547下的Mac OS X 10.9上安装ruby-odbc gem，以与通过ODBC连接到SAP系统的rails 2.3.12应用程序一起使用。

环境

Mac OS X 10.9(小牛)

装有ruby 1.9.3和其他 ruby 的

RVM

Gems for Rails 2.3.12应用程序

酿造

已安装iODBC的

情况

gem系统在执行时使构建失败

gem install ruby-odbc 

提示无法像中那样找到 sql.h

ERROR: sql.h not found

然后，我尝试通过以下方式告诉gem安装环境ODBC header 位于何处:

gem install ruby-odbc -- --with-odbc-dir=/usr/local/iODBC

但这仍然失败，并显示以下消息( 基本上仍然找不到sql.h头文件)。

在这一点上-卡住了，无法获得构建的gem

Answer 1

解决了问题。关键是将gem安装为

gem install ruby-odbc -- --with-odbc-dir=/usr/local/iODBC/

之前的关键步骤是按照以下步骤重新安装软件堆栈

安装Homebrew:请参见-通过命令

来 Brew

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

安装RVM

$ \curl -sSL https://get.rvm.io | bash -s stable

安装Ruby-1.9.3，供与ODBC

连接的应用程序使用

rvm install ruby-1.9.3

安装iODBC系统，请参见:iODBC Wiki

有多个版本，其中Mac OX版本作为DMG文件提供，用于在应用程序中安装驱动程序管理器，以及构建ruby-odbc gem所需的头文件。

安装ruby-odbc gem

ruby -odbc gem 在 Ruby ODBC中进行了描述。这描述了原始源的构建，但是gem install生态系统将获取源并进行构建。

gem install ruby-odbc -- --with-odbc-dir=/usr/local/iODBC/

重要的部分是已安装的头文件和库的路径，这些文件通过iODBC安装到/usr/local/iODBC中。

成功是当您收到通常已安装gem的愉快消息时，如下所示:

gem install ruby-odbc -- --with-odbc-dir=/usr/local/iODBC/
