Problem with the gnu linker (ld.exe)

[alphabetagamma]

Code: Select all

ld -v
file k_entry.o
file kernel.o

gives the results in the addition.

by the way:
when i use the assembler command "-f elf" instead of "-f aout" and then try to link it with "ld -T kernel.ld kernel.o k_entry.o" i get:
ld: cannot perform PE operations ons non PE output file 'a.exe'.

Hi,

The problem is with kernel.o. Post the results of:

Code: Select all

gcc -v

Also, try recompiling kernel.o. It's been compiled with the cygwin standard compiler, not the crosscompiler.

[alphabetagamma]

ok then how can i substitute the cygwin gcc for the cross gcc ?

[JamesM]

did you do the "export PATH=..." command I gave you?

[alphabetagamma]

yes but i didnt use "i686-elf-gcc" i think i need that command and not "gcc".

the new cygwin output in addition.

[JamesM]

Excellent - in k_entry.asm, change the "call _k_main" to "call k_main", and you should be sorted.

one more error:
i686-elf-ld -T kernel.ld kernel.o k_entry.o

i686-elf-ld: warning: cannot find entry symbol start; defaulting to ff800000


edit: addition: thats what i changed...had to change the fourth line "[extern _k_main]" to "[extern k_main]" otherwise he says "undefined defined symbol k_main" at the call...

[JamesM]

... and change "_start" to "start"? Come on, surely you could work that out?

[alphabetagamma]

i tried all combinations..perhabs the adress ist wrong ?
ff800000 ?
