制做arm工具链:gcc-4.5_binutils-2.20.1_eglibc-2.10.1

参考CLFS和一个项目,CLFS-SYSROOT提供了很多理论基础,那个项目则更加实际

host系统为debian sid 32bit,系统需求基本按照CLFS的

耗时2个多小时,中间遇到些问题,顺利的话1.5个小时内能搞定

我做了两遍toolchain都遇到编译gcc pass1的问题:

../libgcc':

configure: error: cannot compute suffix of object files: cannot compile

第一次:

网友说是$LD_LIBRARY_PATH变量没设置,后来发现debian本身没有设置这个变量,但前几天安装ICC时自动设置了,这个情况下系统会优先使用这个变量的值而非默认值,所以先把它加上$TOOLDIR/lib,还是不行.按照那个google code项目设置LDFLAGS,就好了

第二次:

变量$TARGET_CFLAGS设置错误

ppl-0.10.2在configure时没法识别gmp-5.0.1说是没找到xx版本以上的gmp,所以用稍微旧一点的4.3.1

ppl和cloog-ppl不是必须的,可以不编译,相应的gcc和eglibc中configure不要带上他们两个

下面是编译脚本,源码包的URL地址在几个月后可能会失效,到时候google之

bash -e意思是出错就退出,到时候查看done文件和出错信息,推荐一步步走,因为很容易出错
