  • Linux下C++开发常用命令

          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

    1 [root@lzv6 c++]# g++ -E -o vec2.cpp vec.cpp 
    2 [root@lzv6 c++]# wc vec.cpp vec2.cpp 
    3     33     71    557 vec.cpp
    4  20958  45683 534803 vec2.cpp
    5  20991  45754 535360 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

     1     [root@lzv6 c++]# ldd vec
     2     linux-vdso.so.1 =>  (0x00007fff8fbff000)

     8     
     9     [root@lzv6 c++]# ldd -v vec  // -v 表示 打印所有信息,例如包括符号的版本信息
