Ubuntu 10.04 下编译交叉工具链arm-linux-gcc 4.5.1

前文「Ubuntu 10.04 下编译交叉工具链GCC 4.5.1 」编译出来的交叉工具链不管是在编译内核还是应用程序都存在这样或者那样的问题。分析原因主要是因为采用的是newlib，所以编译的工具比较适合编译内核，应用程序不合适。这次使用glibc，编译出来的交叉工具链比较成功。具体步骤如下：

1. 下载二进制文件处理工具集合binutils-2.20.1.tar.bz2，下载地址为 http://ftp.gnu.org/gnu/binutils/binutils-2.20.1.tar.bz2
2. 下载GNU编译器集合gcc-4.5.1.tar.bz2(也可仅下载core和g++)，下载地址为 http://gcc.parentingamerica.com/releases/gcc-4.5.1/gcc-4.5.1.tar.bz2
3. 下载编译GCC-4.5.0的依赖库:
   gmp-5.0.1.tar.bz2: 下载地址为 ftp://ftp.gmplib.org/pub/gmp-5.0.1/gmp-5.0.1.tar.bz2
   mpfr-3.0.0.tar.bz2: 下载地址为 http://www.mpfr.org/mpfr-current/mpfr-3.0.0.tar.bz2
   mpc-0.8.2.tar.gz: 下载地址为 http://www.multiprecision.org/mpc/download/mpc-0.8.2.tar.gz
4. 下载C运行时库glibc的相关安装包及补丁:
   glibc-2.11.tar.bz2，下载地址为 ftp://ftp.gnu.org/gnu/glibc/glibc-2.11.tar.bz2
   glibc-ports-2.11.tar.bz2，下载地址为 ftp://ftp.gnu.org/gnu/glibc/glibc-ports-2.11.tar.bz2
   glibc-2.11-libgcc_eh-1.patch，下载地址为 http://blog.csdn.net/Matrix_Designer/archive/2010/10/31/5977783.aspx (原始地址为 http://www.freesa.org/repositories/entry/freesa/patches/glibc-2.11-libgcc_eh-1.patch?rev=557f86a37891e17e39570db4a5aaead7159d1a37 )
5. 下载linux内核源码linux-2.6.20.tar.bz2，地址为ftp://ftp.kernel.org/pub/linux/kernel/v2.6/linux-2.6.20.tar.bz2
6. 下载调试器gdb-7.2.tar.bz2，下载地址为 http://ftp.gnu.org/gnu/gdb/gdb-7.2.tar.bz2
7. 将所有文件都拷贝到同一目录下，然后进入此目录，执行：gedit Makefile &

8. sudo make all
9. sudo make clean

10. gedit ~/.bashrc &
在文件末尾添加以下内容：
export PATH=/opt/arm-linux-tools/bin:$(PATH)

至此，工具编译成功。内核和应用程序都可以成功编译，编译的应用程序可以下载到板子上运行(测试过s3c2410)。这个配置也可以用来编译arm-none-linux-gnueabi-gcc，默认使用eabi来编译应用程序，还可以用它来编译eabi配置的内核。

至此安装成功！如果是动态链接的程序，板子上需要拷贝相关的库文件到/lib目录下，具体的文件如下：

/opt/arm-linux-tools/arm-linux/lib/libc.so.6
/opt/arm-linux-tools/arm-linux/lib/libc-2.11.so
/opt/arm-linux-tools/arm-linux/lib/ld-linux.so.2
/opt/arm-linux-tools/arm-linux/lib/libgcc_s.so.1
/opt/arm-linux-tools/arm-linux/lib/libm.so.6
/opt/arm-linux-tools/arm-linux/lib/libdl.so.2
/opt/arm-linux-tools/arm-linux/lib/librt.so.1
/opt/arm-linux-tools/arm-linux/lib/libpthread.so.0
/opt/arm-linux-tools/arm-linux/lib/libpthread-2.11.so
/opt/arm-linux-tools/arm-linux/lib/libstdc++.so.6
/opt/arm-linux-tools/arm-linux/lib/libstdc++.so.6.0.14

前四个文件是必须的，其他的是可选的

 

复制时可以执行下面脚本：

cp /opt/arm-linux-tools/arm-linux/lib/libc* ~/opt/tslib/lib
cp /opt/arm-linux-tools/arm-linux/lib/ld-linux* ~/opt/tslib/lib
cp /opt/arm-linux-tools/arm-linux/lib/libgcc_s* ~/opt/tslib/lib
cp /opt/arm-linux-tools/arm-linux/lib/libm* ~/opt/tslib/lib
cp /opt/arm-linux-tools/arm-linux/lib/libdl* ~/opt/tslib/lib
cp /opt/arm-linux-tools/arm-linux/lib/librt* ~/opt/tslib/lib
cp /opt/arm-linux-tools/arm-linux/lib/libpthread* ~/opt/tslib/lib
cp /opt/arm-linux-tools/arm-linux/lib/libstdc++* ~/opt/tslib/lib

 

最后要添加开发板的LD_LIBRARY_PATH：

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/lib
