用crosstool0.43建立ARM－Linux 交叉编译环境

 

http://blog.chinaunix.net/u1/34474/showart.php?id=361474

 

(这绝对是一个好blog)

 

整个过程是按照上面的做的，但会出现一个问题：

checking for a BSD-compatible install... /usr/bin/install -c
checking whether ln -s works... yes
checking for pwd... /bin/pwd
checking for arm-9tdmi-linux-gnu-gcc... gcc
checking version of gcc... 4.3.2, bad
checking for gnumake... no
checking for gmake... gmake
checking version of gmake... 3.81, ok
configure: error:
*** These critical programs are missing or too old: gcc
*** Check the INSTALL file for required versions.

 

然后找到下面的网页：

http://blog.gotokernel.com/?p=33

crosstool的目录中通常包含了我们常见问题的patch。

进入patches/glibc-2.3.2 修改/glibc-2.3.3-allow-gcc-4.0-configure.patch

将

+ 3.[2-9]*|4.[01]*)

改为

+ 3.[2-9]*|4.*)

不知道为什么要这样做。。。

后来将内核换成2.6.30.4，也是一次编译成功。。。不过还不知道能不能用。。。

 

成功后的信息：

kernel 2.6.22
