Hi all!
I am reposting the previous problem, as after some investigation the
problem is more clear:there is some error creating a PIC EXECUTABLE in a
POWER-PC Debian6!
Even when creating the simplest code:
int main() {}
compiling with "gcc -fPIC" and then linking with "gcc -Wl,-pie" produces
non PIC code:
checking all the linked object files (also those added by gcc) with
"readelf -d myobjectfile | fgrep TEXT" all seem to be PIC as nothing is
produced by the previous command.
Oddly giving the command "readelf -d mypie_executable | fgrep TEXT" to
my final 'PIC' output executable I get: "0x00000016 (TEXTREL) 0x0"
Then if I try to load the file with QEMU-USER I get: "error while
loading shared libraries: R_PPC_REL24 relocation at 0xb31f95a0 for
symbol `__libc_start_main' out of range" !!!
If I link with "-shared" all is fine and the library is PIC.. Also if I
create a normal executable, or a normal executable relocated at linker
time with "-Wl,-Ttext-segment=myaddress" all is fine..
I think the linker goes crazy as I want a PIC executable not a library!
I am creating the binaries using Debian 6 kernel 2.6.32.5 powerpc
running in a qemu VM, with gcc 4.4.5-8, binutils 2.20.1 eglibc 2.11.2-10
I have outputs of dumps of objdump, readelf, and Map here:

Please help!! I really dunno how to solve it!
Thank you very much in advance!
Stefano B.
