linux如何安装交叉工具链,Linux：制作mipsel 交叉工具链 （更新版）

１．代码结构为：

setup ---》 源代码压缩包

src ---》源码

~/code/cross-compile$ ls src/

binutils-2.24 gcc-4.7.1 gdb-7.6.2 glibc-2.18

build --》 编译目录

：~/code/cross-compile$ ls build/

binutils gcc gdb glibc

kernel ----》 内核代码：

~/code/cross-compile/kernel$ ls

linux-3.10

２．编译 binutils

在build/binutils 下，执行命令：

。./。./src/binutils-2.24/configure --target=mipsel-linux-gnueabi --prefix=/home/charles/code/cross-compile/embedded-toolchain/cross-tools --with-sysroot=/home/charles/code/cross-compile/embedded-toolchain

然后，执行 make， make install 安装

3. 编译 GCC stage 1

在 build/gcc目录下，执行

AR=ar LDFLAGS=“-Wl，-rpath=/home/charles/code/cross-compile/embedded-toolchain/cross-tools/lib” 。./。./src/gcc-4.7.1/configure --prefix=/home/charles/code/cross-compile/embedded-toolchain/cross-tools --target=mipsel-linux-gnueabi --with-sysroot=/home/charles/code/cross-compile/embedded-toolchain --with-gmp=/usr/local --with-mpfr=/usr/local --with-ppl=/usr/local --with-newlib --without-headers --disable-multilib --disable-nls --disable-decimal-float --disable-libgomp --disable-libmudflap --disable-libssp --disable-shared --disable-threads --enable-languages=c --with-float=soft --with-arch=mips32r2 --with-tune=mips32r2

然后，

make all-gcc all-target-libgcc

make install-gcc install-target-libgcc

4. 安装内核头文件

进入到内核代码目录，

执行命令：

ARCH=mips make mrproper

ARCH=mips make headers_check

ARCH=mips CROSS_COMPILE=mipsel-gcc-linux-gnueabi make INSTALL_HDR_PATH=/home/charles/code/cross-compile/embedded-toolchain/usr headers_install

find /home/charles/code/cross-compile/embedded-toolchain/usr/include/ -name “.install” -or -name “。.install.cmd” | xargs rm -fv ;\

5. 编译 GLIBC

进入到 build/glibc，执行

BUILD_CC=gcc CC=mipsel-linux-gnueabi-gcc AR=mipsel-linux-gnueabi-ar RANLIB=mipsel-linux-gnueabi-ranlib 。./。./src/glibc-2.18/configure --prefix=/usr --host=mipsel-linux --enable-add-ons --with-fp=no libc_cv_forced_unwind=yes libc_cv_c_cleanup=yes libc_cv_ctors_header=yes --with-tune=mips32r2 --with-arch=mips32r2 --with-headers=/home/charles/code/cross-compile/embedded-toolchain/usr/include

把步骤3生成的mipsel gcc 加入到 path：

export PATH=$PATH:/home/charles/code/cross-compile/embedded-toolchain/cross-tools/bin

执行

make

make install install_root=/home/charles/code/cross-compile/embedded-toolchain

6.编译最后的GCC

AR=ar LDFLAGS=“-Wl，-rpath=/home/c++harles/code/cross-compile/embedded-toolchain/cross-tools/lib” 。./。./src/gcc-4.7.1/configure --prefix=/home/charles/code/cross-compile/embedded-toolchain/cross-tools --target=mipsel-linux-gnueabi --with-sysroot=/home/charles/code/cross-compile/embedded-toolchain --with-gmp=/usr/local --with-mpfr=/usr/local --with-ppl=/usr/local --disable-multilib --disable-libssp --disable-nls --disable-libstdcxx-pch --with-arch=mips32r2 --with-tune=mips32r2 --enable-languages=c，c++ --with-float=soft --with-mips-plt --disable-libgomp --disable-libmudflap --enable-poison-system-directories --enable-symvers=gnu --enable-long-long --enable-threads --enable-shared --enable-lto --enable-__cxa_atexit --with-gnu-as --with-gnu-ld

再执行

make all-gcc -j10 -i -k

make all-target-libgcc

make install-gcc

make install-target-libgcc

make

make install

最后，看一下生成的gcc的信息：

。/mipsel-linux-gnueabi-gcc -v

Using built-in specs.

COLLECT_GCC=。/mipsel-linux-gnueabi-gcc

COLLECT_LTO_WRAPPER=/home/charles/toolchain/embedded-toolchain/cross-tools/bin/。./libexec/gcc/mipsel-linux-gnueabi/4.7.1/lto-wrapper

Target： mipsel-linux-gnueabi

Configured with： 。./。./src/gcc-4.7.1/configure --prefix=/home/charles/code/cross-compile/embedded-toolchain/cross-tools --target=mipsel-linux-gnueabi --with-sysroot=/home/charles/code/cross-compile/embedded-toolchain --with-gmp=/usr/local --with-mpfr=/usr/local --with-ppl=/usr/local --disable-multilib --disable-libssp --disable-nls --disable-libstdcxx-pch --with-float=soft --with-arch=mips32r2 --with-tune=mips32r2 --enable-languages=c，c++ --with-float=soft --with-mips-plt --disable-libgomp --disable-libmudflap --enable-poison-system-directories --enable-symvers=gnu --enable-long-long --enable-threads --enable-shared --enable-lto --enable-__cxa_atexit --with-gnu-as --with-gnu-ld

Thread model： posix
