dockerfile指令，linux g++ 鏈接,Linux G++將64位共享庫代碼鏈接到靜態庫

如果對象模塊將在共享庫中使用,則始終需要“位置獨立代碼”。它高度依賴于平臺,并且會產生一些開銷。

您必須在amd64而不是x386上顯式指定它的原因只是它恰好是x86的默認值,而不是amd64。

還要注意“-fpic”和“-fpic”之間的區別:

dockerfile指令、-fpic

Generate position-independent code (PIC) suitable for use in a

shared library, if supported for the target machine. Such code

accesses all constant addresses through a global offset table

linux內核源碼，(GOT). The dynamic loader resolves the GOT entries when the pro-

gram starts (the dynamic loader is not part of GCC; it is part

of the operating system). If the GOT size for the linked execu-

table exceeds a machine-specific maximum size, you get an error

cmake 靜態庫鏈接靜態庫？message from the linker indicating that -fpic does not work; in

that case, recompile with -fPIC instead. (These maximums are 8k

on the SPARC and 32k on the m68k and RS/6000. The 386 has no

such limit.)

linux移動文件命令、Position-independent code requires special support, and there

fore works only on certain machines. For the 386, GCC supports

PIC for System V but not for the Sun 386i. Code generated for

the IBM RS/6000 is always position-independent.

-fPIC

If supported for the target machine, emit position-independent

code, suitable for dynamic linking and avoiding any limit on the

Position-independent code requires special support, and therefore
