How to link the object files(.o) into one BIG object file with "Symbols partly located" ?

Question

Hi,"Symbols partly located" is means:Link some .o files with option "-Ttext 0xXXXXXX" of "ld" (fixed theoffset of .text segment), So I want the "ld" will locate the .text with symbols those arealready exist in .o files .   keep the undefined symbols for an other follow link.But ,"ld" will fail to output *BIG* .o file. Because there areundefined symbols.Please give your advice, thank you. (to the exclusion of dynmaiclibrary solution ,please)ELF symbol table:                  CONTENTS, READONLYSYMBOL TABLE:...00007414 l     F .text  0000002c _ZN6CToolsD0Ev00000604 l     O .rodata        00000008 _ZTI4CMgr0000728c l     F .text  0000006c _ZN4CMgrD1Ev000072f8 l     F .text  00000074 _ZN4CMgrD0Ev

Doesn't "ld -r -o big.o -Ttext 0xXXXXX foo.o bar.o ..." do exactly whatyou want?Cheers,-- In order to understand recursion you must first understand recursion.Remove /-nsp/ for email.

Hi Paul,

Thank for your advice. But ld with "-r" will output object with all symbols NOT located(the output just like a Normal .o file, not doing any location).

I want ld will output a "partial" located object: Those symbols already exisit in foo.o bar.o ... need be update into all .text segment. And, keep the undefined(*UND*) symbols for ld again.

Cheers,

Tangkun
