Background
I have used these instuctions in the past to successfully build toolchains for Didj. They are based on instructions I originally found at http://blog.leshak.ru/english/pages/how-to-build-cross-toolchain-arm-uclibc-eabi-using-crosstool-ng/
(That site was not responding as of this writing).
Download and unpack crosstool-NG (latest version 1.7.1 as of 17 July 2010)
cd ~ wget http://ymorin.is-a-geek.org/download/crosstool-ng/crosstool-ng-1.7.1.tar.bz2 tar -xjvf crosstool-ng-1.7.1.tar.bz2 cd crosstool-ng-1.7.1
Configure and install
./configure --prefix=$HOME/ctng make make install
Add the path to the ct-ng
export PATH=$PATH:$HOME/ctng/bin
Create a temporary folder for the assembly of the package
cd ~ mkdir toolchain-build cd toolchain-build
Copy preconfigured config files
cp ../ctng/lib/ct-ng-1.7.1/samples/arm-unknown-linux-uclibcgnueabi/* . mv crosstool.config .config
If necessary, you can change the configuration
ct-ng menuconfig
You can usually just change the path to the cross-toolchain
nano .config
Configure CT_PREFIX_DIR
CT_PREFIX_DIR="/opt/ctng"
Run the compilation, get a coffee - have lunch, etc. (after “.” You can specify the number of concurrently running tasks, I set = number of cores in my system)
ct-ng build.4
An example log of a successful compilation: (There is one more step after this finishes)
