XEN problem with libelf-tools.c during compilation
Hi,
I am trying install XEN 4.2.1 on Slackware 14, I am getting an error message during compilation. I have already installed libelf.
Code:
In function 'elf_access_unsigned':
../../xen/common/libelf/libelf-tools.c:45:28: error: '__w.__l[1]' may be used uninitialized in this function [-Werror=uninitialized]
../../xen/common/libelf/libelf-tools.c: In function 'elf_access_signed':
../../xen/common/libelf/libelf-tools.c:73:28: error: '__w.__l[1]' may be used uninitialized in this function [-Werror=uninitialized]

part of libelf-tools.c (line 45 and 73 are underlined)
Code:
uint64_t elf_access_unsigned(struct elf_binary * elf, const void *ptr,
uint64_t offset, size_t size)
{
int need_swap = elf_swap(elf);
const uint8_t *u8;
const uint16_t *u16;
const uint32_t *u32;
const uint64_t *u64;
switch ( size )
{
case 1:
u8 = ptr + offset;
return *u8;
case 2:
u16 = ptr + offset;
return need_swap ? bswap_16(*u16) : *u16;
case 4:
u32 = ptr + offset;
return need_swap ? bswap_32(*u32) : *u32;
case 8:
u64 = ptr + offset;
return need_swap ? bswap_64(*u64) : *u64;
default:
return 0;
}
}
int64_t elf_access_signed(struct elf_binary *elf, const void *ptr,
uint64_t offset, size_t size)
{
int need_swap = elf_swap(elf);
const int8_t *s8;
const int16_t *s16;
const int32_t *s32;
const int64_t *s64;
switch ( size )
{
case 1:
s8 = ptr + offset;
return *s8;
case 2:
s16 = ptr + offset;
return need_swap ? bswap_16(*s16) : *s16;
case 4:
s32 = ptr + offset;
return need_swap ? bswap_32(*s32) : *s32;
case 8:
s64 = ptr + offset;
return need_swap ? bswap_64(*s64) : *s64;
default:
return 0;
}
Does someone know how to solve this problem?
Thank you |
