如何交叉编译mkfs.jffs2等工具链mtd-utils(包括zlib.so库和lzo.so库)

acl_2.2.47.orig.tar.gz
lzo-2.03.tar.gz
mtd-utils_20080508.orig.tar.gz
zlib-1.2.3.tar.gz

mkfs.jffs2.for.arm-linux-gcc.3.4.1平台.tar.bz2
mkfs.jffs2.for.arm-linux-gcc.4.3.2平台.tar.bz2
mkfs.jffs2.for.pc平台.tar.bz2


如果只需要mkfs.jffs2工具,那么ubuntu 8.10下直接安装jffnms软件包即可,
luther@gliethttp:~$ sudo apt-get install jffnms
如果需要将jffs2移植到arm开发板上,那么就需要下载源码进行交叉编译了,这就是本文的内容.

1.下载工具软件源码包
luther@gliethttp:~$ wget
luther@gliethttp:~$ wget
luther@gliethttp:~$ wget
luther@gliethttp:~$ mkdir libs 用来存放下面生成的lib库.

2.编译zlib库
luther@gliethttp:~/zlib-1.2.3$ ./configure --prefix=~/libs --shared
对于交叉编译输入如下指令
luther@gliethttp:~/zlib-1.2.3$ CC=arm-linux-gcc ./configure --prefix=~/libs --shared
luther@gliethttp:~/zlib-1.2.3$ make -j4
luther@gliethttp:~/zlib-1.2.3$ make install
luther@gliethttp:~$ tree ~/libs
/home/ubuntu/libs
|-- include
|   |-- zconf.h
|   `-- zlib.h
|-- lib
|   |-- libz.so -> libz.so.1.2.3
|   |-- libz.so.1 -> libz.so.1.2.3
|   `-- libz.so.1.2.3
`-- share
    `-- man
        `-- man3
            `-- zlib.3

5 directories, 6 files
这就表示完成了.

3.编译lzo库
luther@gliethttp:~/lzo-2.03$ ./configure --prefix=/home/ubuntu/libs --enable-shared
对于交叉编译输入如下指令
luther@gliethttp:~/lzo-2.03$ CC=arm-linux-gcc ./configure --host=arm-linux --prefix=/home/ubuntu/libs --enable-shared --disable-static
这个还必须要绝对路径才行.
luther@gliethttp:~/lzo-2.03$ make
luther@gliethttp:~/lzo-2.03$ make install
luther@gliethttp:~$ tree ~/libs
.
|-- include
|   |-- lzo
|   |   |-- lzo1.h
|   |   |-- lzo1a.h
|   |   |-- lzo1b.h
|   |   |-- lzo1c.h
|   |   |-- lzo1f.h
|   |   |-- lzo1x.h
|   |   |-- lzo1y.h
|   |   |-- lzo1z.h
|   |   |-- lzo2a.h
|   |   |-- lzo_asm.h
|   |   |-- lzoconf.h
|   |   |-- lzodefs.h
|   |   `-- lzoutil.h
|   |-- zconf.h
|   `-- zlib.h
|-- lib
|   |-- liblzo2.a
|   |-- liblzo2.la
|   |-- liblzo2.so -> liblzo2.so.2.0.0
|   |-- liblzo2.so.2 -> liblzo2.so.2.0.0
|   |-- liblzo2.so.2.0.0
|   `-- libz.a
`-- share
    `-- man
        `-- man3
            `-- zlib.3

6 directories, 22 files
手工将静态库删掉就行了,
如果是arm平台还需要strip优化.

4.编译mtd-utils-20080508前的准备工作.
编译之前的代码工作
luther@gliethttp:~$ wget
luther@gliethttp:~$ mkdir libs/include/sys -p
luther@gliethttp:~$ cp acl-2.2.47/include/acl.h libs/include/sys
luther@gliethttp:~/mtd-utils-20080508$ export LD_LIBRARY_PATH=~/libs/lib:$LD_LIBRARY_PATH
如果还找不到-llzo2,那么把他拷到/usr/lib下,对于交叉编译器,就是拷贝到
比如
luther@gliethttp:~/libs/lib$ sudo cp -a * /vobs/tools/arm-tools/arm-linux-gcc-3.4.1/arm-linux/lib/
luther@gliethttp:~/mtd-utils-20080508$ vim Makefile
修改安装路径
DESTDIR=.
SBINDIR=gliethttp/sbin
MANDIR=gliethttp/share/man
INCLUDEDIR=gliethttp/include
修改CFLAGS变量
CFLAGS := -I./include -I/home/ubuntu/libs/include $(OPTFLAGS)
如果是arm-linux-gcc定义为
CFLAGS := -I./include -I/home/ubuntu/libs/include -DAI_ADDRCONFIG=0x0020 $(OPTFLAGS)
来自/usr/include/netdb.h
luther@gliethttp:~/mtd-utils-20080508$ vim ubi-utils/Makefile
DESTDIR := ~/mtd-utils-20080508
SBINDIR=gliethttp/sbin
MANDIR=gliethttp/share/man
INCLUDEDIR=gliethttp/include

luther@gliethttp:~/mtd-utils-20080508$ vim recv_image.c
拷贝/usr/include/netinet/in.h文件中
arm-linux-gcc中不需要拷贝它.
struct ip_mreq
{
    /* IP multicast address of group.  */
    struct in_addr imr_multiaddr;

    /* Local IP address of interface.  */
    struct in_addr imr_interface;
};
结构体数据到头部,否则在u盘版的ubuntu 8.10上老是提示没有ip_mreq定义,虽然上面明明写了#define _USE_MISC
arm-linux-gcc中还需要创建如3下个目录
luther@gliethttp:~/mtd-utils-20080508$ mkdir arm-linux
luther@gliethttp:~/mtd-utils-20080508$ cp -r ubi-utils arm-linux/
luther@gliethttp:~/mtd-utils-20080508$ cp -r include arm-linux/

luther@gliethttp:~/mtd-utils-20080508$ vim ubi-utils/src/libpfiflash.c
将所有EBUF(PFIFLASH_ERRSTR[-rc]);全部替换为EBUF("%s", PFIFLASH_ERRSTR[-rc]);
vim下替换脚本为
:%s/EBUF(PFIFLASH_ERRSTR\[-rc\]);/EBUF("\%s", PFIFLASH_ERRSTR\[-rc\]);/g
luther@gliethttp:~/mtd-utils-20080508$ vim ubi-utils/src/ubimirror.c
将第206行的
fprintf(stderr, err_buf);
改为
fprintf(stderr, "%s", err_buf);  // 想法是好的,因为err_buf中含有%d等format信息,这样接口更加统一,但是编译器似乎还并不支持这样的操作.[luther.gliethttp]
luther@gliethttp:~/mtd-utils-20080508$ vim ubi-utils/src/unubi.c
将第898行
char fname[PATH_MAX];
改为
char fname[PATH_MAX+1];
luther@gliethttp:~/mtd-utils-20080508$ cd ubi-utils/new-utils
因为-O2优化的原因,会导致如下log信息
error: ignoring return value of ‘scanf’, declared with attribute warn_unused_result
所有手工先编译.o
luther@gliethttp:~/mtd-utils-20080508/ubi-utils/new-utils$ gcc -Iinclude -Isrc -I../../include -Wall -Werror -Wall src/ubiformat.c -c -o ubiformat.o
对于交叉编译执行如下1条语句
luther@gliethttp:~/mtd-utils-20080508/ubi-utils/new-utils$ arm-linux-gcc -Iinclude -Isrc -I../../include -Wall -Werror -Wall src/ubiformat.c -c -o ubiformat.o
luther@gliethttp:~/mtd-utils-20080508/ubi-utils/new-utils$ cd -

好了,上面的所有修改完成之后,就可以执行make成功编译了[luther.gliethttp].
luther@gliethttp:~/mtd-utils-20080508$ make
如果是交叉编译,执行
luther@gliethttp:~/mtd-utils-20080508$ make CROSS=arm-linux-

luther@gliethttp:~/mtd-utils-20080508$ make install
对于交叉编译,执行
luther@gliethttp:~/mtd-utils-20080508$ make CROSS=arm-linux- install

luther@gliethttp:~/mtd-utils-20080508$ tree gliethttp/
