1、proc编译器配置问题

在使用proc将.pc文件编译成.c文件时出现一堆的错误,网上的答案七杂八杂的,都没有解决我的问题。

如下是我在使用过程中的一些错误:

由于我可能比较笨,实在是受不了网上那些奇奇怪怪的答案,所以只能乖乖的自己去琢磨,根据错误来看,应该是跟头文件有关

所以我查询了下proc编译器的配置文件,如下

PS:这个是我后面改回来的,反正差不多就是这样。。。。

然后我一开始想是不是这里面涉及到的gcc版本跟我的系统上的不一样,然后就直接去一个一个进去看,例如cd /usr/lib/gcc-lib/x86_64-redhat-linux/3.4.3/include

得出的结果是未找到这个文件,因为我的CentOS的gcc有两个版本(不是特别懂)就是有一个4.8.2和4.8.5的文件夹,其中刚好有Include文件夹,点开有一堆gcc头文件

所以我就将原本的配置文件的版本参数改成这两个版本参数。

然后,重新编译,成功!如下:

另:这是配置文件的路径:$ORACLE_HOME/precomp/admin/pcscfg.cfg

2、我们成功使用proc xxxx.pc编译成.c文件了,但是却不能编译由C++所写的文件,否则出现以下错误

[oracle@localhost mytest]$ proc testHello1.pc

这是因为预编译工具proc,它是完成Pro*C源程序到纯C程序的转换

proc iname=filename [OptionName1=value1]…[OptionNameN=valueN]

常用编译选项

       INAME=path and filename (name of the input file) 

         ONAME=path and filename (name of the output file) 

         INCLUDE=path  (头文件所在路径)

         --INCLUDE =路径名 或 INCLUDE =(路径名1,路径名2)

         PARSE=FULL | PARTIA | NONE (default FULL for C, Others for C++) 

         CODE=ANSI_C | CPP (default ansi_c)

         USERID=username/password

以上是它的常用编译选项,如果要想将.pc转换成.cc的c++源程序要这样:proc iname=test.pc parse=none code=cpp oname=test.cc

然后编译c++源程序时,要使用g++,这应该都知道的,哈哈哈~

PS:我觉得proc的编译挺麻烦的,要编译两次,后面自己写了个脚本方便多了,然后才发现有个makefile这个东西。。。。。。。。。
