Howto Install Ltib in
Fedora 10
Author:
misty (qibing(a)yahoo.com.cn)
本文档是说明如何在Fedora
10系统上安装Freescale
提供的Ltib安装包。Ltib(Linux
Target Imagine
Build)是可以为不同平台开发和配置BSP的工具。Freescale为不同的平台(包括PowerPC,ColdFire,ARM等)提供来不同的Ltib,可以使用户很方便地移植Uboot,移植Linux内核,以及制作文件系统,使用Ltib只需要进行简单的配置,就可以帮我们完成其余的工作。
准备工作
首先到Freescale的网站上下载自己平台的BSP包,下载地址为:
http://www.freescale.com/webapp/sps/site/overview.jsp?code=CW_BSP
我下载的是MPC8349EA_MDS_K26_20061221-LTIB.iso,这是为MPC8349EA开发板提供的BSP。
安装Ltib
下载了BSP的ISO文件后,挂载这个iso文件,
下面操作的假设条件:
MPC8349EA_MDS_K26_20061221-LTIB.iso在/home/qibing/目录下;
安装ltib到/home/qibing/ppc/目录下;
“#”表示当前是以root权限操作;
“$”表示当前是以普通用户权限操作;
#cd
/home/qibing
#mount
-o loop MPC8349EA_MDS_K26_20061221-LTIB.iso /mnt
$cd
/mnt
$./intall
注:当提示输入ltib的安装路径时,输入/home/qibing/ppc
$cd
/home/qibing/ppc
$cd
ltib
下面就要安装ltib了,但是在Fedora
10上按照的时候会有很多问题,我以走过这个流程的身份先把将要遇到的问题提出来,并解决这些问题,这样下面的安装过程才顺利。
如果这时运行./ltib则会遇到两个问题:
1.
ltib安装是普通用户权限,但是部分操作需要root用户权限。按照提示进行如下操作,
#/usr/sbin/visudo
然后在文件最后添加如下内容:
qibing ALL =
NOPASSWD:/bin/rpm, /opt/freescale/ltib/usr/bin/rpm
注:visudo实际就是编辑文件/etc/sudoers文件
2.
提示缺少rpm-build包。
通过$rpm
-qrpm-build命令查看rpm-build包已经安装了,这可能是ltib的问题或者其他函数的问题,解决方法是(从论坛上摘录的):
From the directory where
you type "./ltib" type "gedit ltib" if you
have a Gnome install. I'm not sure what the KDE editor is, or use
VI if you want edit in the console text mode. Search for
"pre_install_deps". This is the table that
"check_basic_deps" refers to. Look for a line that
contains " rpm-buld 0". Comment out the line by adding
"#" to the left of the line. Save and you should be good
to go.
如果这时继续运行./ltib安装,则还会有问题,我自己的error
log文件弄丢了,这是网上摘录的:

解决的方法是:在运行./ltib之前,修改”dist/lfs-5.1/bison/bison.spec”文件,在%Build段修改make为make
CFLAGS=-O0。然后再运行./ltib。
接着会遇到下面的问题,
+ umask 022
+ cd
/opt/freescale/ltib/usr/src/rpm/BUILD
+ cd mtd
+ make -C util

解决方法是:修改“[color="#000000"]/opt/freescale/pkgs/mtd-utils-20060302-cf-byteswap_h-1.patch”文件,下面是网上论坛中摘录的解决方法:
[color="#000000"]Hi,
I
had the same problem under Ubuntu 9.04. I solved it by modifying
the lines 46, 47 and 48 of the
"/opt/freescale/pkgs/mtd-utils-20060302-cf-byteswap_h-1.patch"
[color="#000000"]file.
+#if
!defined _BYTESWAP_H && !defined _NETINET_IN_H
+#
error "Never use directly; include
instead."
[color="#000000"]+#endif
[color="#000000"]by
+//#if
!defined _BYTESWAP_H && !defined _NETINET_IN_H
+//#
error "Never use directly; include
instead."
[color="#000000"]+//#endif
(very
cheap solution, but ... it works :-) )
然后删除掉“/opt/freescale/ltib/usr/src/rpm/BUILD/mtd”这个目录,最后再运行./ltib,最后安装成功^_^。
使用Ltib
