Problems in compiling a hello world module under 2.6.x 2005-07-17 - By narjes richkine
Back
Dear All,
I compiled a hello_world kernel module sample under
2.6.x and failed to load the module.
I am using gcc 3.4.2.
$insmod hello.o
insmod: error inserting 'hello.o': -1 Invalid module
format
$strace insmod hello.o
(...)
open("/lib/tls/libc.so.6", O_RDONLY) = 3
read(3,
"\177ELF\1\1\1\0\0\0\0\0\0\0\0\0\3\0\3\0\1\0\0\0
\177u\000"..., 512) = 512
fstat64(3, {st_mode=S_IFREG|0755, st_size=1512400,
...}) = 0
old_mmap(0x743000, 1207532, PROT_READ|PROT_EXEC,
MAP_PRIVATE|MAP_DENYWRITE, 3, 0) = 0x743000
old_mmap(0x864000, 16384, PROT_READ|PROT_WRITE,
MAP_PRIVATE|MAP_FIXED|MAP_DENYWRITE, 3, 0x120000) =
0x864000
old_mmap(0x868000, 7404, PROT_READ|PROT_WRITE,
MAP_PRIVATE|MAP_FIXED|MAP_ANONYMOUS, -1, 0) = 0x868000
close(3) = 0
old_mmap(NULL, 4096, PROT_READ|PROT_WRITE,
MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0xf6fde000
mprotect(0x864000, 8192, PROT_READ) = 0
mprotect(0x73b000, 4096, PROT_READ) = 0

seg_not_present:0, useable:1}) = 0
munmap(0xf6fdf000, 131481) = 0
brk(0) = 0x9702000
brk(0x9723000) = 0x9723000
open("hello.o", O_RDONLY) = 3

read(3, "", 15408) = 0
close(3) = 0
init_module("ELF", 0x3d0) = -1 ENOEXEC (Exec
format error)
write(2, "insmod: error inserting \'hello.o"...,
60insmod: error inserting 'hello.o': -1 Invalid module
format
) = 60
exit_group(1) = ?
Does any one got it work under 2.6.x ? (it works under
2.4.x).
Any idea for creating .ko rather than .o?
Thanks,
--Narjess.
