linker - ld 中 -Bstatic 标志的各种表示

Question

在 ld 的联机帮助页中(来自 binutils)，这部分是关于 -Bstatic 的变体旗帜:

-Bstatic
-dn
-non_shared
-static
Do not link against shared libraries. This is only meaningful on platforms for which shared libraries are supported. The different variants of this option are for compatibility with various systems. You may use this option multiple times on the command line: it affects library searching for -l options which follow it. This option also implies --unresolved-symbols=report-all. This option can be used with -shared. Doing so means that a shared library is being created but that all of the library's external references must be resolved by pulling in entries from static libraries.

我的问题是关于粗体句子:这些变体究竟要兼容哪些系统？我都看过 -Bstatic和 -static在各种项目中，但到目前为止还没有看到有人使用其余的两个变体。为了获得最大的兼容性(就跨平台而言)，最好使用哪一种？

Answer 1

-Bstatic和 -static选项当前使用，并且不一样:

-static意味着:执行完全静态链接(根本不使用共享库)。

-Bstatic意思是:对于任何 -lfoo接下来，仅使用库的存档版本。

其他选项:-dn (1993 年添加)和 -non_shared (在 1994 年添加)是为了与过时的操作系统兼容。
