看到程序在運行了嗎？
5、編譯咱們的uClinux內核
首先解壓
shell
代碼:
tar zxvf uClinux-dist-20040408.tar.gz
這是在你解壓的目錄裏面會生成一個 uClinux-dist目錄
shell 中進 uClinux-dist目錄，執行make menuconfig進行配置，我猜你遇到了和我同樣的問題：
dom
代碼:
wenwu@wenwu-desktop:/source/uClinux-dist$ make menuconfig
config/mkconfig > config.in
make -C /source/uClinux-dist/config/scripts/lxdialog all
make[1]: Entering directory `/source/uClinux-dist/config/scripts/lxdialog'
/usr/bin/ld: cannot find -lncurses
collect2: ld 返回 1
-e
>> Unable to find the Ncurses libraries.
>>
>> You must have Ncurses installed in order
>> to use 'make menuconfig'
make[1]: *** [ncurses] 錯誤 1
make[1]: Leaving directory `/source/uClinux-dist/config/scripts/lxdialog'
make: *** [menuconfig] 錯誤 2
wenwu@wenwu-desktop:/source/uClinux-dist$
config/mkconfig > config.in
make -C /source/uClinux-dist/config/scripts/lxdialog all
make[1]: Entering directory `/source/uClinux-dist/config/scripts/lxdialog'
/usr/bin/ld: cannot find -lncurses
collect2: ld 返回 1
-e
>> Unable to find the Ncurses libraries.
>>
>> You must have Ncurses installed in order
>> to use 'make menuconfig'
make[1]: *** [ncurses] 錯誤 1
make[1]: Leaving directory `/source/uClinux-dist/config/scripts/lxdialog'
make: *** [menuconfig] 錯誤 2
wenwu@wenwu-desktop:/source/uClinux-dist$
實際上是沒有安裝ncurses開發包，安裝就是了
在新立得軟件管理器中找到libncurses5-dev，安裝
用的朋友喜歡用make xconfig，直接運行會出現以下錯誤：
socket
代碼:ide
wenwu@wenwu-desktop:/source/uClinux-dist$ sudo make xconfig
config/mkconfig > config.in
make -C /source/uClinux-dist/config/scripts tkparse
make[1]: Entering directory `/source/uClinux-dist/config/scripts'
make[1]: 「tkparse」是最新的。
make[1]: Leaving directory `/source/uClinux-dist/config/scripts'
ARCH=dummy /source/uClinux-dist/config/scripts/tkparse < config.in > config.tmp
cat /source/uClinux-dist/config/scripts/header.tk >> ./config.tk
cat config.tmp >> config.tk
rm -f config.tmp
echo "set defaults \"/dev/null\"" >> config.tk
echo "set help_file \"config/Configure.help\"" >> config.tk
cat /source/uClinux-dist/config/scripts/tail.tk >> config.tk
chmod 755 config.tk
make: wish：命令未找到
make: *** [xconfig] 錯誤 127
config/mkconfig > config.in
make -C /source/uClinux-dist/config/scripts tkparse
make[1]: Entering directory `/source/uClinux-dist/config/scripts'
make[1]: 「tkparse」是最新的。
make[1]: Leaving directory `/source/uClinux-dist/config/scripts'
ARCH=dummy /source/uClinux-dist/config/scripts/tkparse < config.in > config.tmp
cat /source/uClinux-dist/config/scripts/header.tk >> ./config.tk
cat config.tmp >> config.tk
rm -f config.tmp
echo "set defaults \"/dev/null\"" >> config.tk
echo "set help_file \"config/Configure.help\"" >> config.tk
cat /source/uClinux-dist/config/scripts/tail.tk >> config.tk
chmod 755 config.tk
make: wish：命令未找到
make: *** [xconfig] 錯誤 127
解決辦法是在新立得軟件包管理器中找到如下幾項並安裝，而後再運行make xconfig就能夠看到圖形界面了。
tcl8.4
tcl8.4-dev
tk8.4
k8.4-dev
而後再進行配置：在下面這個選項裏面選擇GDB ARMulator，怎麼選擇應該不用再說了吧？
oop
代碼:
--- Select the Vendor you wish to target
(GDB) Vendor
--- Select the Product you wish to target
(ARMulator) GDB Products
(GDB) Vendor
--- Select the Product you wish to target
(ARMulator) GDB Products
Kernel選擇2.4內核，Libc Version選擇uC-libc
ui
代碼:
(linux-2.4.x) Kernel Version
(uC-libc) Libc Version
[ ] Default all settings (lose changes)
[ ] Customize Kernel Settings
[ ] Customize Vendor/User Settings
[ ] Update Default Vendor Settings
(uC-libc) Libc Version
[ ] Default all settings (lose changes)
[ ] Customize Kernel Settings
[ ] Customize Vendor/User Settings
[ ] Update Default Vendor Settings
退出它會提示：
es5
代碼:
Do you wish to save your new kernel configuration?
< Yes > < No >
< Yes > < No >
選擇Yes
這個時候就能夠進行編譯了，編譯首先用make dep
而後用make
很不幸，咱們的錯誤老是不斷存在！
spa
代碼:
arm/clone.S: Assembler messages:
arm/clone.S:34: Error: undefined symbol `EINVAL' in operation
make[3]: *** [arm/clone.o] 錯誤 1
make[3]: Leaving directory `/source/uClinux-dist/lib/libc/sysdeps'
make[2]: *** [subdirs] 錯誤 1
make[2]: Leaving directory `/source/uClinux-dist/lib/libc'
make[1]: *** [all] 錯誤 2
make[1]: Leaving directory `/source/uClinux-dist/lib'
make: *** [subdirs] 錯誤 1
arm/clone.S:34: Error: undefined symbol `EINVAL' in operation
make[3]: *** [arm/clone.o] 錯誤 1
make[3]: Leaving directory `/source/uClinux-dist/lib/libc/sysdeps'
make[2]: *** [subdirs] 錯誤 1
make[2]: Leaving directory `/source/uClinux-dist/lib/libc'
make[1]: *** [all] 錯誤 2
make[1]: Leaving directory `/source/uClinux-dist/lib'
make: *** [subdirs] 錯誤 1
但有時候，就是由於這些錯誤使咱們不斷前行。
其實不少人都遇到了這個錯誤 ，是上面的庫文件選擇錯了，什麼？錯了你還寫在上面？我是想讓你有更深的記憶！
make clean把上次編譯過程生成的中間文件刪除
而後make menuconfig
此次，咱們把Libc Version換成uClibc
代碼:
(uClibc) Libc Version
再重複上面的步驟：
代碼:
make dep
make
make
這個編譯過程比較長，耐心等待。
編譯成功後會在uClinux-dist目錄裏面生成一個p_w_picpaths目錄，這個目錄裏面有四個文件：
p_w_picpath.bin:這是包含內核映像和 romfs文件系統映像，能夠寫到Flash中的文件，
linux.data:包括內核全部的數據段
linux.text：包括內核全部的代碼段
romfs.img:文件系統
另外在uClinux-dist/linux-2.4.x目錄裏面生成了兩個文件：linux和system.map
linux:linux內核文件
system.map:內核符號表
而後在uClinux-dist目錄裏面建一個skyeye.conf文件，並鍵入如下配置文件
代碼:
#skyeye config file sample
cpu: arm7tdmi
mach: at91
mem_bank: map=M, type=RW, addr=0x00000000, size=0x00004000
mem_bank: map=M, type=RW, addr=0x01000000, size=0x00400000
mem_bank: map=M, type=R, addr=0x01400000, size=0x00400000, file=./boot.rom
mem_bank: map=M, type=RW, addr=0x02000000, size=0x00400000

mem_bank: map=M, type=RW, addr=0x04000000, size=0x00400000
mem_bank: map=I, type=RW, addr=0xf0000000, size=0x10000000
cpu: arm7tdmi
mach: at91
mem_bank: map=M, type=RW, addr=0x00000000, size=0x00004000
mem_bank: map=M, type=RW, addr=0x01000000, size=0x00400000
mem_bank: map=M, type=R, addr=0x01400000, size=0x00400000, file=./boot.rom
mem_bank: map=M, type=RW, addr=0x02000000, size=0x00400000
mem_bank: map=M, type=RW, addr=0x02400000, size=0x00008000
mem_bank: map=M, type=RW, addr=0x04000000, size=0x00400000
mem_bank: map=I, type=RW, addr=0xf0000000, size=0x10000000
注意這個配置文件中須要boot.rom 文件系統，可是咱們並無生成boot.rom文件系統，怎麼辦？
ln -s p_w_picpaths/romfs.img boot.rom
代碼:
wenwu@wenwu-desktop:/source/uClinux-dist$ ln -s p_w_picpaths/romfs.img boot.rom
這是就能夠在uClinux-dist 目錄裏面看到boot.rom這個文件
下面就能夠用skyeye運行咱們本身編譯出來的內核了。
代碼:
wenwu@wenwu-desktop:/source/uClinux-dist$ skyeye -e linux-2.4.x/linux
big_endian is false.
