摘錄部份重點

这纯属软件bug，因为使用open函数的时候，如果在第二个参数中使用了 O_CREAT，就必须添加第三个参数：创建文件时赋予的初始权限。而在gcc-3.3.6/gcc/的collect2.c文件中有漏掉第三个参数的错误，而gcc-4.3对语法错误的检查严格是出了名的(4.1就不会因此错误退出)，所以就退出了。

將系統的gcc版本換成4.1版本
參考

install gcc-4.1 under Ubuntu

ln -s nelson-arm.sh nelsonbuild
./nelsonbuild

這樣編譯
還是有一樣的問題

修改nelsonbuild
拿掉--nounpack

重新來一次

哇靠
上面的修改都不用
就成功了

gcc版本要換成4.1是關鍵阿
