安装了光盘里的arm-Linux-gcc后,怎么显示arm-Linux-gcc版本是4.2.4呢?

1)首先我安装了一个4.2.4版本的arm-linux-gcc.
2)接着我买了tiny6410的开发板子,看到里面的版本是4.5.1
3)我又安装了4.5.1版本的arm-linux-gcc.
4)问题是: 我用arm-linux-gcc -v来查看版本信息,版本信息一直是4.2.4,没有变成4.5.1.而我用这个4.2.4版本来编译光盘里面的内核等东西,都出现问题.请问怎么样才能够安装到4.5.1版本的arm-linux-gcc?

请各位牛人帮忙解答下哈,谢谢.

所以自己在编译U-BOOT时候出现了问题.错误提示如下:
/usr/local/bin/arm-linux-ld.real: ERROR: Source object board/samsung/mini6410/nand_6410.fo has EABI version 5, but target u-boot has EABI version 0

/usr/local/bin/arm-linux-ld.real: failed to merge target specific data of file board/samsung/mini6410/nand_6410.fo
make: *** [u-boot] 错误 1

编译动作是到u-boot-mini6410的目录下面,执行
make mini6410_nand_config-ram256
make

请哪位大牛指点.

你有试过下面的命令吗？(假设你是按照默认路径安装的)

export PATH=/opt/FriendlyARM/toolschain/4.5.1/bin:$PATH

我是按照默认路径安装的.就是手册里面的如下要求来安装:
Step2:把编译器路径加入系统环境变量,运行命令
#gedit /root/.bashrc
编辑/root/.bashrc 文件,注意“bashrc”前面有一个“.”
,修改最后一行为 export
PATH=$PATH: /opt/FriendlyARM/toolschain/4.5.1/bin,注意路径一定要写对,否则将不会有
效。
如图,保存退出。
重新登录系统(不必重启机器,开始->logout 即可),使以上设置生效,在命令行输入
arm-linux-gcc –v,会出现如下信息,这说明交叉编译环境已经成功安装。

可是我的系统不是Fedora,我的是深度的Deepin Linux,所以"开始->logout"这个命令不起作用,请教怎么在deepin linux下面重新登陆系统呢?

by the way,编译uboot还是失败.

版主,gcc版本已经是4.5.1了,编译过了刚才的地方,可是后面还是出现同样的错误,打印信息如下,难道光盘里面带的4.5.1编译器不能够用来编译光盘里面的UBOOT吗?要怎么解决呢?求大牛帮忙..

我用光盘上的arm-linux-gcc-4.5.1-v6-vfp-20101103.tgz编译u-boot-mini6410-20111018.tar.gz没有问题。如果你用的是和我一样的源代码，可能你需要重新解压缩uboot确保源代码目录是干净的。

我的步骤是
$sudo tar -C / -xzf arm-linux-gcc-4.5.1-v6-vfp-20101103.tgz
$export PATH=/opt/FriendlyARM/toolschain/4.5.1/bin:$PATH
$tar -xzf u-boot-mini6410-20111018.tar.gz
$cd u-boot-mini6410
$make ARCH=arm CROSS_COMPILE=arm-linux- mini6410_nand_config-ram256
$make ARCH=arm CROSS_COMPILE=arm-linux- all
