设置全局gcc默认搜索路径

跑步时

arm-none-linux-gnueabi-gcc -print-search-dirs | grep libraries | sed 's/:/\n/g'

我得到以下输出：

libraries
 =/opt/codesourcery/lib/gcc/arm-none-linux-gnueabi/4.4.1/
/opt/codesourcery/lib/gcc/arm-none-linux-gnueabi/4.4.1/../../../../arm-none-linux-gnueabi/lib/arm-none-linux-gnueabi/4.4.1/
/opt/codesourcery/lib/gcc/arm-none-linux-gnueabi/4.4.1/../../../../arm-none-linux-gnueabi/lib/
/opt/codesourcery/arm-none-linux-gnueabi/libc/lib/arm-none-linux-gnueabi/4.4.1/
/opt/codesourcery/arm-none-linux-gnueabi/libc/lib/
/opt/codesourcery/arm-none-linux-gnueabi/libc/usr/lib/arm-none-linux-gnueabi/4.4.1/
/opt/codesourcery/arm-none-linux-gnueabi/libc/usr/lib/

当交叉编译一些包时，能够附加到这些路径将使我的生活更加轻松。我知道-L选项，并且我想使用它，但是许多包在交叉编译时不尊重它，而且在codesourcery中使用它会导致问题。（详情见本帖末尾）。基本上，我有一个完整的目录树，其中包含编译包所需的所有文件，我想将该目录树添加到默认搜索路径中。例如，这样-print search dirs也将输出类似于以下内容的路径：

/target/usr/lib
/target/lib

除了已经列出的路径之外。我不是在寻找特定于CodeSource的答案，因为我有几个工具链可以使用

对于那些好奇的人，这里是codesourcery安装的错误：

工作

失败原因：

/lib/libc.so.6: file not recognized: File format not recognized
collect2: ld returned 1 exit status

很明显，这是从主机上获取libc。我见过不止一个工具链出现这种情况，但不是全部

针对一项评论： 这是的输出
