Easy to build toolchain, cross-ng

因DIMM-PC只有32 MByte Flash Disk，
所以用glibc會太大，
因此改用jserv前輩所建議crosstool next generation[cross-ng]，
這個crosstool可以編glibc和uclibc，
且介面跟編kernel很類似喔!!
真的方便超多的...^^

1. install

$ wget -c http://ymorin.is-a-geek.org/download/crosstool-ng/
crosstool-ng-0.3.2.tar.bz2
$ tar -jxvf crosstool-ng-0.3.2.tar.bz2
$ cd crosstool-ng-0.3.2
$ ./configure --prefix=/opt/cross-ng
$ make
# make install

2. using cross-ng

$ export PATH="${PATH}:/opt/cross-ng/bin"
$ mkdir toolchain-dev && cd ./toolchain-dev
$ ct-ng menuconfig

需要提供uclibc的設定檔路徑

$ ct-ng build

成功囉!!
