Use crosstool-ng to compile the cross tool chain

Steps:

1, download crosstool-ng, for the http://ymorin.is-a-geek.org/download/crosstool-ng/ to the license download together. 2. Install the following software package: 1) libncurses5-dev2) bison3) flex4) texinfo5) automake6) libtool7) patch8) gcj9) cvs10) cvsd11) gawk12) aria213) curl

14) libncursesw5-dev

15) g ++ 16) Subversion

3. decompress, patch (if any), and create a working directory. 1) mkdir crosstool-ng-build # crosstool-ng compile the working directory. 2) mkdir crosstool-ng-install # crosstool-ng installation directory 3) CD crosstool-ng-xx4 ). /configure -- prefix =/home/workspace/uboot/crosstool-ng_install # configure the crosstool-ng5) make # compile the crosstool-ng6) make install # Install the crosstool-ng4, configure the cross-compiled toolchain for this compilation 1) CD .. /crosstool-ng_build/# enter the working directory for compiling the new cross compiler 2) CP .. /crosstool-ng-XX/samples/ARM-unknown-Linux-gnueabi /*. /# copy the default configuration file to work Directory 3) mV crosstool. config. config # Modify file name 4 ).. /crosstool-ng-1.6.1_install/bin/CT-ng menuconfig # Enter menuconfig and start modifying configuration 5.
