mtd_utils交叉编译

1. 材料准备

1.     zlib-1.2.3.tar.gz：http://download.chinaunix.net/download.php?id=40893&ResourceID=12241

2.     lzo-2.10.tar.gz：http://www.oberhumer.com/opensource/lzo/download/lzo-2.03.tar.gz

zlib的编译：

CC=arm-linux-gcc ./configure --shared --prefix=…/out/

root@Jon:/home/jon/code/H3_NEO/mtd_utils/zlib# CC=arm-linux-gcc  ./configure --shared --prefix=../out/
Checking for shared library support...
Building shared library libz.so.1.2.5 with arm-linux-gcc.
Checking for off64_t... Yes.
Checking for fseeko... Yes.
Checking for unistd.h... Yes.
Checking whether to use vs[n]printf() or s[n]printf()... using vs[n]printf().
Checking for vsnprintf() in stdio.h... Yes.
Checking for return value of vsnprintf()... Yes.
Checking for attribute(visibility) support... Yes.

执行make

root@Jon:/home/jon/code/H3_NEO/mtd_utils/zlib# make
arm-linux-gcc -O3 -D_LARGEFILE64_SOURCE=1   -c -o example.o example.c
arm-linux-gcc -O3 -D_LARGEFILE64_SOURCE=1   -c -o adler32.o adler32.c
arm-linux-gcc -O3 -D_LARGEFILE64_SOURCE=1   -c -o compress.o compress.c
arm-linux-gcc -O3 -D_LARGEFILE64_SOURCE=1   -c -o crc32.o crc32.c

执行make install

 root@Jon:/home/jon/code/H3_NEO/mtd_utils/zlib# make install
cp libz.a ../out//lib
cp libz.so.1.2.5 ../out//lib
cd ../out//lib; chmod u=rw,go=r libz.a
cp zlib.3 ../out//share/man/man3
chmod 644 ../out//share/man/man3/zlib.3
cp zlib.pc ../out//lib/pkgconfig
chmod 644 ../out//lib/pkgconfig/zlib.pc
cp zlib.h zconf.h ../out//include
chmod 644 ../out//include/zlib.h ../out//include/zconf.h
root@Jon:/home/jon/code/H3_NEO/mtd_utils/zlib#

2. 编译安装lzo：
执行配置：

CC=arm-linux-gcc ./configure --host=arm-linux
–prefix=/home/jon/code/H3_NEO/mtd_utils/out/

然后

make
make install

3. 编译安装e2fsprogs:

./configure --host=arm-linux --host=arm-linux --enable-elf-shlibs
–prefix=/home/jon/code/H3_NEO/mtd_utils/out/
然后

make
make install

4. 编译mtd-utils:
修改makefile在头部加入如下2行

CROSS=arm-linux-
WITHOUT_XATTR=1

直接编译还是会报错，因为我的目的只是希望得到flash_*相关的工具,因此，直接把其他的注掉即可，如下:

CROSS=arm-linux-
WITHOUT_XATTR=1
# -*- sh -*-

VERSION = 1.5.2

CPPFLAGS += -D_GNU_SOURCE -I./include -I$(BUILDDIR)/include -I./ubi-utils/include $(ZLIBCPPFLAGS) $(LZOCPPFLAGS) $(UUIDCPPFLAGS)

ifeq ($(WITHOUT_XATTR), 1)
  CPPFLAGS += -DWITHOUT_XATTR
endif
ifeq ($(WITHOUT_LZO), 1)
  CPPFLAGS += -DWITHOUT_LZO
else
  LZOLDLIBS = -llzo2
endif
