当存在同名的共享库时，如何强制与静态库链接 [英] How can I force linking with a static library when a shared library of same name is present

问题描述

假设我有一个使用 sin（）函数的文件 main.cpp ，它在 libmath 。另外假设我们在同一个目录中都有libmath.a和libmath.so。现在，如果我发出命令 g ++ -o main main.cpp -lmath ，Linux的默认行为是链接到共享库 libmath.so 。我想知道是否有办法强制程序与静态库 libmath.a 链接，而不删除或移动共享库？

解决方案

您需要将-static传递给链接器，但仅限于您需要的特定库。例如：

  g ++ -o main main.cpp -Wl，-Bstatic -lmath -Wl，-Bdynamic 
  

Suppose I have a file main.cpp which uses sin() function which is defined in libmath. Also suppose that we have both libmath.a and libmath.so available in the same directory. Now if I issue the command g++ -o main main.cpp -lmath the default behaviour of Linux is to link to the shared library libmath.so. I want to know is there a way to force the program to link with the static library libmath.a without deleting or moving the shared library?

解决方案

You'll need to pass the -static to the linker, but only for particular libraries you want. e.g.:

g++ -o main main.cpp -Wl,-Bstatic -lmath -Wl,-Bdynamic
