今天编译在Mac下编译了Oracle的SQL驱动插件,这里记录编译过程供参考。
今天编译在Mac下编译了Oracle的SQL驱动插件,这里记录编译过程供参考。
先介绍一下编译环境:Mac OS X 10.7.3, 安装Qt SDK 1.2 for Mac,XCode 4.2.1。
1. 首先是到Oracle的网站上下载相关的库和开发包,按照Qt文档中的说明(How to Build the OCI Plugin on Unix and Mac OS X),需要下载"Instant Client Package - Basic"和"Instant Client Package - SDK"两个包,可以从这里找到要下载的内容。
2. 把下载的zip文件解压到同一个目录下,如Oracle10gClient;
3. 编译。在qt的文档中有两种方法,一个是利用configure生成makefile在执行make,另一种是利用qmake生成makefile再生成。我这里用第一种方法没有成功(原因不详),这里说的是第二种方法:
1)进入Qt源码目录,~/QtSDK/QtSources/4.8.0/src/plugins/sqldrivers/oci
2) 执行qmake命令, 按照文档中的说明,执行
这里的[your_oracle_dir]需要替换为第2步创建的目录。然后再执行make生成库文件。
在执行时make发现无法找到
这样是可以编译成功的,但是在最后link时还有一个错误,无法找到库文件“library not found for -lclntsh”,查找了oracle的安装目录下,确实没有这个文件,但有一个libclntsh.dylib.10.1,猜测这个就是一个动态库,只是版本不同的问题。于是给这个文件做个符号链接,在[your_oracle_dir]目录下执行
ln -s libclntsh.dylib.10.1 libclntsh.dylib
然后再回头去执行make命令,就可以创建成功了。创建后的文件在~/QtSDK/QtSources/4.8.0/src/plugins/sqldrivers/oci目录下,把它们复制到Qt的sqldrivers目录下就可以了。
以上就是整个生成驱动插件的过程。
