最近在HP-UX下用HP ANSI C编译了Python 2.4.3和cx_Oracle-4.2。
在import cx_Oracle的时候出现错误。

网络上大部分方法是用gcc3.x编译。经过多日摸索，用HP ANSI C编译的方法如下。
方法1. 设置环境变量LD_PRELOAD。

setenv LD_PRELOAD /usr/lib/libcl.2
python
import cx_Oracle

方法2. 静态连接libcl.sl (-lcl)

setenv ORACLE_HOME /oracle/product/10.1.0.2
setenv LDFLAGS '-lcl'

重新编译python

用下面的方法重新编译 cx_Oracle

modify setyp.py from
libPath = os.path.join(oracleHome, "lib")
to
libPath = os.path.join(oracleHome, "lib32")

python setyp.py build
python setyp.py install
