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

Hi,

"Symbols partly located" is means:

Link some .o files with option "-Ttext 0xXXXXXX" of "ld" (fixed the offset of .text segment), So I want the "ld" will locate the .text with symbols those are already exist in .o files . keep the undefined symbols for an other follow link.

But ,"ld" will fail to output *BIG* .o file. Because there are undefined symbols.

Please give your advice, thank you. (to the exclusion of dynmaic library solution ,please)

ELF symbol table:

CONTENTS, READONLY SYMBOL TABLE: ...

00007414 l F .text 0000002c _ZN6CToolsD0Ev 00000604 l O .rodata 00000008 _ZTI4CMgr 0000728c l F .text 0000006c _ZN4CMgrD1Ev 000072f8 l F .text 00000074 _ZN4CMgrD0Ev

Doesn't "ld -r -o big.o -Ttext 0xXXXXX foo.o bar.o ..." do exactly what you want?

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
