我使用strace检测到这一点:

], [/* 26 vars */]) = 0
8480 open("/home/bjack/lib/libgame_std.so", O_RDONLY) = 12
8480 open("/home/bjack/lib/libygor.so", O_RDONLY) = -1 ENOENT (No such file or directory)
8480 open("/home/bjack/lib/libygor.a", O_RDONLY) = -1 ENOENT (No such file or directory)
我很困惑;根据手册ld首先必须尝试找到-rpath-link
路径。
答案 0 :(得分:3)
-rpath-link
仅记录(在ld(1)手册页中)以影响依赖于其他共享库的共享库。因为你要链接一个可执行文件,要么被忽略,要么被视为另一个-rpath。或者这可能意味着-rpath-link路径仅用于递归依赖,但是在链接可执行文件时会设置它。
无论如何,我认为它没有被使用,因为你没有一个库取决于另一个。
