本页面记录本人在Linux下进行C++开发时使用的常用命令,注意这里不包括比如ls,mv等linux命令,这里会持续更新。
首先假设你只有一个源程序文件,叫vec.cpp,编译后的可执行程序叫vec(本文最后附有该程序Demo)。
本人是在Centos6.4 64bit系统上进行测试的,GCC版本是4.4.7。
1. strings命令:查看系统glibc支持的版本
[root@lzv6 c++]# strings /usr/lib64/libstdc++.so.6 | grep GLIBC
GLIBCXX_3.4
GLIBCXX_3.4.1
GLIBCXX_3.4.2
GLIBCXX_3.4.3
GLIBCXX_3.4.4
GLIBCXX_3.4.5
GLIBCXX_3.4.6
GLIBCXX_3.4.7
GLIBCXX_3.4.8
GLIBCXX_3.4.9
GLIBCXX_3.4.10
GLIBCXX_3.4.11
GLIBCXX_3.4.12
GLIBCXX_3.4.13
GLIBC_2.2.5
GLIBC_2.3
GLIBC_2.4
GLIBC_2.3.2
GLIBCXX_FORCE_NEW
GLIBCXX_DEBUG_MESSAGE_LENGTH
[root@lzv6 c++]# strings /lib64/libc.so.6 | grep GLIBC_
GLIBC_2.2.5
GLIBC_2.2.6
GLIBC_2.3
GLIBC_2.3.2
GLIBC_2.3.3
GLIBC_2.3.4
GLIBC_2.4
GLIBC_2.5
GLIBC_2.6
GLIBC_2.7
GLIBC_2.8
GLIBC_2.9
GLIBC_2.10
GLIBC_2.11
GLIBC_2.12
GLIBC_PRIVATE
2. g++ -E选项:预处理源文件
[root@lzv6 c++]# g++ -E -o vec2.cpp vec.cpp
[root@lzv6 c++]# wc vec.cpp vec2.cpp
vec.cpp
vec2.cpp
总用量
上面每行分别代表行数、单次数、字节数。
从这里也可以看出引入多余头文件是件多么可怕的事情,多引入一个头文件,就要预处理N行。你可以试着#include <stdio.h>,然后再看看增加了多少行。
3. ldd命令:显示目标文件的依赖库
[root@lzv6 c++]# ldd vec
