gcc: error: elf_i386: No such file or directory
OBJCOPY arch/x86/vdso/vdso32-int80.so
objcopy:  arch/x86/vdso/vdso32-int80.so.dbg : No such file
make[2]: *** [arch/x86/vdso/vdso32-int80.so] Error 1
make[1]: *** [arch/x86/vdso] Error 2
make: *** [arch/x86] Error 2
------------------------------------------------------------------------------------------------------
SOLUTION:
----------
The problem is that gcc 4.6 doesn t support anymore linker-style architecture options.
Apply the following changes to solve the problem :
In arch/x86/vdso/Makefile :
replace "-m elf_x86_64" by "-m64" on the line starting with VDSO_LDFLAGS_vdso.lds
replace "-m elf_i386" by "-m32" on the line starting with VDSO_LDFLAGS_vdso32.lds

SOLUTION:
---------
struct igbvf_buffer {
dma_addr_t dma;
struct sk_buff *skb;`enter code here`
union {
/* Tx */
struct {
unsigned long time_stamp;
u16 length;
u16 next_to_watch;
u16 mapped_as_page;
};
/* Rx */
struct {
struct page *page; <--------------- No 1
u64 page_dma;
unsigned int page_offset;
};
};
struct page *page; <------------ No 2
};
Hmm conflict of a member with a transparent union.
Maybe older gccs didn t catch that. But it looks very broken
