Published at March 14, 2012 · Piotr Król · 2 min read
You might be surprised at how much you have to make to correctly build arm-unknown-linux-gnueabi config based toolchain with crosstool-ng. As you can see examples of many open source projects, the man’s work is a rare resource. The result of this economic fact is that the attempt to build configuration arm-unknown-linux-gnueabi is not a simple task and during an operation you can come across many problems. Although I am not afraid of problems and effectively try to fight them and of course sharing the results of my work....

One day I asked myself the trouble searching for host name generator. Best I could find (currently second in the results of google) is rospo.net.
