我的UBUNTU里随光盘就安装有GCC ，。是一个比较新的版本

我在网上下载了一个交叉编译的一套包，是编译 ARC的。。我是想用来开发ARC的固件。


解压后里面有几个文件夹
[img]PICTURE:/home/diro/.tencent/qq//AppData/file//sendpix0.jpg[/img]PICTURE:/home/diro/.tencent/qq//AppData/file//sendpix0.jpg
按REANDME.ARC里提示的去安装。。
.／configure 可以通过，但make 时出现错误
..........以上跑了好多了
checking whether make sets $(MAKE)... yes
checking for style of include used by make... GNU
configure: error: source directory already configured; run "make distclean" there first
make[1]: *** [configure-bfd] 错误 1
make[1]:正在离开目录 `/home/diro/arcbuild/ARC/binutils'
make: *** [all] 错误 2
diro@diro-laptop:~/arcbuild/ARC/binutils$
diro@diro-laptop:~/arcbuild/ARC/binutils$


按这里提示的错误* [configure-bfd] 错误 1
在MAKEFILE里找在这里面有太多的这个提示了

readme.arc里是这样提示的
I) Building /Installing
=======================

Building is best done is a separate directory to the source tree, this enables
quick and clean re-configurations/rebuilds as your needs change.

Un-tar/zip the distribution. Create a build directory, and change into that
directory:

$ mkdir build
$ cd build

这一块我就问题：我没有mkdir 这个 BUILD
因为BINTUILS这个文件夹里有这个BUILD
如果我 cd build,那不是没办法./configure
我的源代码的路径是这里
/home/diro/arcbuild/ARC/binutils'

binutils 下有 SRC 和BUILD两年文件夹

Binutils can be configured to support one of two target types - 'arc-elf32' and
'arc-linux-uclibc'. The former is for 'bare-metal' builds, the latter is for
building user mode Linux applications, to be linked against the uClibc library.

Configure the build, and specify where you want it to be installed (e.g. /opt/arc):

$ ../src/configure --target=arc-elf32 --prefix=/opt/arc --disable-werror
..or..
$ ../src/configure --target=arc-linux-uclibc --prefix=/opt/arc --disable-werror

Make and install

$ make
$ make install
