windows中搜索dll的顺序
一般的顺序就是： exe所在目录--> 当前目录 --> windows system 目录 --> windows 目录 --> $PATH变量所规定的路径
具体的描述可以参看这里： windows MSDN 。
If SafeDllSearchMode is enabled, the search order is as follows:
- The directory from which the application loaded.
- The system directory. Use the GetSystemDirectory function to get the path of this directory.
- The 16-bit system directory. There is no function that obtains the path of this directory, but it is searched.
- The Windows directory. Use the GetWindowsDirectory function to get the path of this directory.
- The current directory.
- The directories that are listed in the PATH environment variable. Note that this does not include the per-application path specified by the App Paths registry key. The App Paths key is not used when computing the DLL search path.
而linux中的搜索路径一般为： 首先 编译链接中的 -L参数， 然后是检查$LD_LIBRARY 路径， 如果还未发现，就会检查/etc/ld.so.conf当中设定的库的路径，
最后是检查 ---> /lib --> /usr/lib 或者下的默认库；
