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
-Werror-implicit-function-declaration \
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.

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.
