linux用proc编译文件出错
因工作需要，我要在centos7 安装oracle11g,我在第一次用proc命令编译.pc文件出现情况如下：
[oracle@localhost programfile]$ proc first.pc

分割线：
起初我被上面的调试信息误导，以为是配置文件没包含"stddef.h"这个文件的路径，于是我用find / - name stddef.h把找到的内容：
/usr/lib/gcc/x86_64-redhat-linux/4.8.2/include/stddef.h
/usr/include/linux/stddef.h
添加到proc的配置文件下 ，我的配置路径是：/data/oracle/product/11.2.0/db_1/precomp/admin/pcscfg.cfg
然而，我再去调用proc first.pc编译发现还是同样的错误，找了很久；最后发现是我的pcscfg.cfg文件内，第一行
sys_include=($ORACLE_HOME/precomp/public,/usr/include,/usr/lib/gcc/x86_64-redhat-linux/4.1.2/include,/usr/lib/gcc/x86_64-redhat-linux/4.4.7/include,/usr/lib/gcc/x86_64-redhat-linux/4.4.4/include,/usr/lib64/gcc/x86_64-suse-linux/4.1.2/include,/usr/lib64/gcc/x86_64-suse-linux/4.3/include)
这里的路径
/usr/lib/gcc/x86_64-redhat-linux/4.1.2/include,
/usr/lib/gcc/x86_64-redhat-linux/4.4.7/include,
/usr/lib/gcc/x86_64-redhat-linux/4.4.4/include,
/usr/lib64/gcc/x86_64-suse-linux/4.1.2/include,
是我系统没有的，然后我把他们删掉，再去找我系统中对应的版本内容，修改后整个pcscfg.cfg如下:
sys_include=($ORACLE_HOME/precomp/public,/usr/include,/usr/lib/gcc/x86_64-redhat-linux/4.8.2/include,/usr/lib/gcc/x86_64-redhat-linux/4.8.5/include)
ltype=short
define=__x86_64__
sys_include=$ORACLE_HOME/oracle
sys_include=/usr/include
sys_include=/$ORACLE_HOME/lib/
保存完成后，再用proc编译文件就成功了！！
最后总结：
用proc编译的时候，出错了，先看调试信息，看缺失的文件是否存在，如果存在的话，再看看配置文件中是否有非法的路径，删掉它们，然后替换自己系统目录下对应的版本路径即可（测试路径很简单，就用cd命令去访问，能访问成功的就是正确的，如果不能访问成功则网上一级访问，一直找到能访问的路径，找到后就查看当前路径底下的内容，然后复制你系统的路径下的版本内容即可）。
