更换Ubuntu 14.04内核时,遇到的一些错误及解决办法

------------------------------------------------------------------------------------------------------

PROBLEM:-1

------------------------------------------------------------------------------------------------------

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

PROBLEM:-2

drivers/net/igbvf/igbvf.h:129:15: error: duplicate member 'page'

make[2]: *** [drivers/net/igbvf] Error 2

make[1]: *** [drivers/net] Error 2

make: *** [drivers] Error 2

------------------------------------------------------------------------------------------------------

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

Comment second pointer.
