【问题】:项目迁移时,原来在suse上正常的代码在centos上报错:

g++ -g -Wall -fPIC -I../include -I./ -I../src -I/share/comm_ext -I/home/appadmin/workspace/comm/export_include/ -I/home/appadmin/workspace/comm/export_include/c2cplatform -I/home/appadmin/workspace/comm/export_include/app_platform -I/home/appadmin/workspace/comm/export_include/app_platform/2.4.1 -c ../include/myutil/net_util.cpp
../include/myutil/net_util.cpp:5:21: 错误:stropts.h:没有那个文件或目录

 

【查找原因】

1. “stropts.h”似乎是系统提供的头文件,那么位于哪个目录下呢?

在suse上使用如下命令:

g++ -g -Wall -fPIC -I../include -I./ -I../src -I/share/comm_ext -I/home/appadmin/workspace/comm/export_include/ -I/home/appadmin/workspace/comm/export_include/c2cplatform -I/home/appadmin/workspace/comm/export_include/app_platform -I/home/appadmin/workspace/comm/export_include/app_platform/2.4.1 -E ../include/myutil/net_util.cpp >util.i

使用g++的 -E选项进行预处理(关于-E选项的更多内容,请自行搜索)

打开util.i,有如下内容:

# 1 "/usr/include/stropts.h" 1 3 4

可知在suse上该文件位于/usr/include/stropts.h

 

2. 再centos上查看,确实不存在/usr/include/stropts.h文件:

find /usr -name *stropts.h*
find: “/usr/lib64/audit”: 权限不够

也就是说,centos上的环境确实缺少该头文件

 

3.既然缺少那就安装。首先需要知道的是,该头文件属于哪个包?

$ yum provides */stropts.h
Loaded plugins: fastestmirror
Loading mirror speeds from cached hostfile
1:compat-glibc-headers-2.5-46.2.x86_64 : Header files for development using standard C libraries.
Repo        : base
Matched from:
Filename    : /usr/lib/x86_64-redhat-linux5E/include/stropts.h
Filename    : /usr/lib/x86_64-redhat-linux5E/include/bits/stropts.h
Filename    : /usr/lib/x86_64-redhat-linux5E/include/sys/stropts.h

可知compat-glibc-headers-2.5-46.2.x86_64包提供我们需要的头文件,我们只需要安装该包就行了。

 

4.先确认一下该包有没有被安装过:

$ yum list|grep installed
CollabNetSubversion-client.x86_64        1.8.10-2                          installed

dal_auto_script.i586                     1-3                               installed

gcc-c++.x86_64                           4.1.2-55.el5                      installed
libgcc.x86_64                            4.1.2-55.el5                      installed
libstdc++.x86_64                         4.1.2-55.el5                      installed
libstdc++-devel.x86_64                   4.1.2-55.el5                      installed
perl_crontab.i586                        1-0                               installed
public_scripts.i586                      1-8                               installed
wget.x86_64                              1.12-1.8.el6                      installed

既然没有,那就安装吧。。。
