没有root权限运行软件时,Linux也为我们提供了一个名为LD_LIBRARY_PATH的环境变量来解决运行时动态库查找路径的解决方案。同样地,由这个环境变量所指定的路径会被装载器/lib/ld-2.12.so优先查找,然后才是动态库库缓存文件/etc/ld.so.cache,风采瞬间就被LD_LIBRARY_PATH给抢完了,/etc/ld.so.cache表示很不高兴。
环境变量LD_LIBRARY_PATH是一个由冒号分隔的目录列表,动态链接器会在这些目录中搜索动态库。你可以使用这个环境变量来添加额外的搜索路径。例如,如果你的动态库位于/path/to/libs目录下,你可以使用以下命令来设置LD_LIBRARY_PATH: export LD_LIBRARY_PATH=/path/to/libs:$LD_LIBRARY_PATH 这个命令会将/path/to/li...
A colon-separated (on Windows, semicolon-separated) list of directories to search for .pc files. The default directory will always be searched after searching the path; the default is libdir/pkg-config:datadir/pkgconfig where libdir is the libdir where pkg-config and datadir is the datadi...
LD_LIBRARY_PATH这个环境变量是大家最为熟悉的,它告诉loader:在哪些目录中可以找到共享库。可以设置多个搜索目录,这些目录之间用冒号分隔开。在linux下,还提供了另外一种方式来完成同样的功能,你可以把这些目录加到/etc/ld.so.conf中,或则在/etc/ld.so.conf.d里创建一个文件,把目录加到这个文件里。当然,这是系...
The first place the dynamic linker should normally look for shared libraries is an executable’s preconfigured runtime library search path (rpath), if it exists. You’ll see how to create this path shortly. Next, the dynamic linker looks in a system cache, /etc/ld.so.cache, to see if ...
LIBRARY_PATH 和 LD_LIBRARY_PATH 的区别: (参考链接) LIBRARY_PATH is used bygccbefore compilationto search directories containing static and shared libraries that need to be linked to your program. LD_LIBRARY_PATH is used by your program to search directories containing shared libraries after it ...
export LD_LIBRARY_PATH=$HOME/gnome1.4/lib:$LD_LIBRARY_PATH 这样能够保证$HOME/gonme-1.4/lib 下的库甚至能够优先于 /usr/lib 下的相同的库被 ld-linux.so.2 调用. export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$HOME/gno me-1.4/lib 这样执行自己的库就不会被优先被加载了. 问题: 是否在自己的环境...
LD_LIBRARY_PATH变量能够覆盖缺省的共享库路径,而不管ldconfig增加新库到系统.如要永久地设置库路径,除非把 LD_LIBRARY_PATH加进如/etc/profile,/etc/bashrc等文件中.否则执行依赖特殊库路径的程序时,每次执行程序时 LD_LIBRARY_PATH都必需重新定义. 所以,事实上选择LD_LIBRARY_PATH或ldconfig没有什么不同,只是取决...
Shared Library Search Path:An optional search path for additional debug symbols (translates to the solib-search-path GDB command). You do not need to have aCMake project with a Linux configurationorMSBuild-based Linux projectopen in Visual Studio to leverage this support. However, if you do ...
