Problem: How to specify Library in ld-Link-Script?

Hi all!

I'm trying to get BootUp-code for x86 (Pentium3) architecture working, using gcc an ld. Because after bootup only the F-Segment is visible to CPU, I need to place the "early" boot-code there. This also includes three libraries needed. How can i specify the libraries, so that the code from them gets into the correct segment?

This is my actual link - script which does NOT work. All libraries are placed in codeExtSeg, although specified in codeStartSeg...!?

MEMORY { /* Just F-Seg */ codeStartSeg : ORIGIN = 0xf0000, LENGTH = 64K - 0x10 /* Rest of code should got here */ codeExtSeg : ORIGIN = 0xfff00000, LENGTH = 512K - 64K - 0x10


codeStartSeg_memory_location = 0xf0000 ; codeStartSeg_file_offset = 0x70000 ;

codeExtSeg_memory_location = 0xfff00000 ; codeExtSeg_file_offset = 0x0 ;


.codeStartSeg codeStartSeg_memory_location : AT (codeStartSeg_file_offset) { target\obj\protected_mode_switch.o(.text .rodata) target\bin\setjmp.o(.text .rodata) target\bin\longjmp.o(.text .rodata) target\bin\bootLib.o(.text .rodata) target\bin\sysLib.o(.text .rodata)

libsfl_p6.a /*************** I'd like to have this libs here in codeStartSeg, but ld places them into codeExtSeg... ?!? */ libsfl_440bx.a libsfl_core.a } >codeStartSeg

.text codeExtSeg_memory_location : AT (codeExtSeg_file_offset) { target\bin\RomTbl.o(.text .rodata)

*(.text) *(.rodata) } >codeExtSeg

Can anyone give me a hint, how to get ld to place the libs into codeStartSeg?

Any help is appreciated! Many thanks,
