[原创]在ubuntu7.10上搭建uClinux编译开发环境并用Skyeye进行仿真

[antonym55]

编译 uClinux-dist-20070130.tar.gz 问题不断

1. 我的是 arm-elf-gcc , 直接make的时候，用的是
make ARCH=arm CROSS_COMPILE=arm-linux- -j4 -C linux-2.6.x || exit 1
make[1]: arm-linux-gcc: Command not found

/bin/sh: arm-linux-gcc: not found

改为 make ARCH=arm CROSS_COMPILE=arm-elf- -j4 -C linux-2.6.x

OK

内核是linux-2.6.22 打了 linux-2.6.22-uc0-big.patch 的补丁

2. make ARCH=arm CROSS_COMPILE=arm-elf- -j4 -C linux-2.6.x 后提示
include/linux/compiler.h:44: #error Sorry, your compiler is too old/not recognized.

#if __GNUC__ >= 4
# include <linux/compiler-gcc4.h>
#elif __GNUC__ == 3 && __GNUC_MINOR__ >= 2
# include <linux/compiler-gcc3.h>
#else
# error Sorry, your compiler is too old/not recognized.
#endif
这里改为直接用 # include <linux/compiler-gcc4.h>

OK

但是不知道为什么不能识别
gcc version 4.1.3 20070929 (prerelease) (Ubuntu 4.1.2-16ubuntu2)

3. 接下来是一堆, 不知怎么解决

error Sorry, your compiler is too old/not recognized.

2.6的内核需要高GCC版本。

我选择了下面的选项:

搞得头大了. 快坚持不住了.

[stlxv]

看累了，再来个调试的例子吧

看累了，再来个调试的例子吧

这两天太忙了，过段时间看看如果有时间就写一个更完整一点的总结出来。

[hoarywolf]

执行 sudo mount -o loop boot.rom /mnt/tmp/
提示：
mount: 您必须指定文件系统类型


怎么回事？

[hulllo]

我跟18楼出现的问题一样了.....

我跟18楼出现的问题一样了.....

原来我uclinux目录在Windows分区下,
负责到Linux分区就没事了.
哈哈

[uusky]

楼主，好贴阿！

非常感谢，我通过LS的如此详细的说明，成功了。呵呵。不错哦！

[bluce]

tks！依楼主方法编译通过
成功！

[free-of-linux]

xiexie

[yan__jiao]

严格地按步骤来了好几遍都是启动时停在Calibrating delay loop ...不动了。后来调试发现，中断不能正常响应。进不了__do_irq()这个函数。为什么？

[Nakedpig]

请教一下你们都用些什么样的开发板的？

[kelvinhan]

顶一个。按楼主方法，一次性通过。
多谢。

今天我用版主的方法在装skyeye，但出现问题了。
问题：（四、测试这个程序）
我安上面的方法依次执行，当在shell中运行代码：skyeye -e linux时，在shell中出现下面代码

arch: arm
cpu info: armv3, arm7tdmi, 41007700, fff8ff00, 0
mach info: name at91, mach_init addr 0x805a2e0
ethmod num=1, mac addr=0:4:3:2:1:f, hostip=10.0.0.1
can't find device module: (null)
log_info: log is off.
log_info:log file is /tmp/test.log, fd is 0x80b12a0
log_info: log start clock 3200000

SKYEYE: use arm7100 mmu ops
Loaded ROM ./boot.rom
exec file "linux"'s format is elf32-little.
start addr is set to 0x00000004 by exec file.[/color]

此时已经死在那里，并没有出现版主提到的那个图形：
