gcc - 链接器如何在没有 SONAME 的情况下找到共享库

Question

如果我创建一个没有像这样的 SONAME 的共享库

gcc -shared libfoo.o -o libfoo.so

并链接到它，
链接器如何找到我的共享库？

是文件名 libfoo.so被链接器视为默认 SONAME？

Answer 1

我想你是正确的。这里 ld 手册页说的是:

-soname=name

When creating an ELF shared object, set the internal DT_SONAME field to the specified name. When an executable is linked with a shared object which has a DT_SONAME field, then when the executable is run the dynamic linker will attempt to load the shared object specified by the DT_SONAME field rather than the using the file name given to the linker.
