c++ - 如果同时存在共享库和动态库，则链接器将首选哪个库？

Question

相同的选项可用于静态链接和动态链接库。
$(CC)$(CFLAGS)-L $(PATH_TO_LIB)-l $(库名)-o输出文件名

如果我的PATH_TO_LIB同时包含.a和.so文件，链接器将首选哪一个文件？

Answer 1

如果链接器是ld的变体，则它将首选共享对象而不是存档。从-l标志的documentation中，强调我的:

-l namespec
--library=namespec

Add the archive or object file specified by namespec to the list of files to link. This option may be used any number of times. If namespec is of the form :filename, ld will search the library path for a file called filename, otherwise it will search the library path for a file called libnamespec.a.

On systems which support shared libraries, ld may also search for files other than libnamespec.a. Specifically, on ELF and SunOS systems, ld will search a directory for a library called libnamespec.so before searching for one called libnamespec.a. (By convention, a .so extension indicates a shared library.) Note that this behavior does not apply to :filename, which always specifies a file called filename.
