生成Uboot Image时碰到的问题记录

make不了的问题缺少宏包

drivers/mtd/nand/nand_base.c:740:3: error: implicit declaration of function ‘dmb’ [-Werror=implicit-function-declaration]
cc1: some warnings being treated as errors
make[3]: *** [drivers/mtd/nand/nand_base.o] Error 1
make[2]: *** [drivers/mtd/nand] Error 2
make[1]: *** [drivers/mtd] Error 2
make: *** [drivers] Error 2

  

查找相应的Ｍakefile.am 文件，删除AM_CXXFLAGS这一行后面的 -Ｗerror选项，然后就可以了。

原错误： variable ‘ion_charge’ set but not used [-Werror=unused-but-set-variable]

原配置文件，Makefile.am 中的前几行：

AM_CXXFLAGS = -Wall -W -Ｗerror $(USEDOUBLES) $(USEDARWIN) $(SEARCH_ENABLED)
            -D_LARGEFILE_SOURCE=1 -D_FILE_OFFSET_BITS=64 -D_GNU_SOURCE

修改后，能股正确通过的：

AM_CXXFLAGS = -Wall -W $(USEDOUBLES) $(USEDARWIN) $(SEARCH_ENABLED)
-D_LARGEFILE_SOURCE=1 -D_FILE_OFFSET_BITS=64 -D_GNU_SOURCE

drivers/net/igbvf/igbvf.h:129:15: error: duplicate member ‘page’ make[3]: *** [drivers/net/igbvf/ethtool.o] Error 1

SOLUTION:

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.

drivers/power/pda_power.c:307:2: error: too few arguments to function ‘otg_get_transceiver’

include/linux/usb/otg.h:170:32: note: declared here

make[2]: *** [drivers/power/pda_power.o] Error 1

 找到otg.h文件里的otg_get_transceiver函数体声明，去掉int id

sudo apt-get可以解决

You can install uboot-mkimage package to get it working.
