当存在同名的共享库时,如何强制链接静态库 [英] How can I force linking with a static library when a shared library of same name is present
问题描述
假设我有一个文件 main.cpp
,它使用 libmath
中定义的 sin()
函数.还假设我们在同一目录中同时拥有 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
.我想知道有没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?
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?
推荐答案
您需要将 -static 传递给链接器,但仅限于您想要的特定库.例如:
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
