GCC cannot find the library file after specifying the link library path

Problem description ：makefile The path and name of the library have been specified in , No error is reported during compilation , But when the program runs, it will report an error that the library file cannot be found .


terms of settlement ：
gcc Medium plus -Wl,-rpath=.

Why? ？
gcc -L Option specifies the dynamic library path when linking , Compile and pass , But the path cannot be found during execution ;
gcc -Wl -rpath Option specifies the path at run time , The runtime finds the dynamic library according to the specified path ;
In other words, when dealing with dynamic link libraries 2 A path ： Link time path and run time path ,2 The two paths are separate .
