0x2: Toolchain for Virtual Development Board

Published at June 7, 2013 · Piotr Król ·  4 min read

Table of contents Introduction What is toolchain ? Why we need cross-toolchain ? How to create toolchain ? Emdebian path Summary Kudos Introduction This is probably the most complicated topic of all related to embedded development but we need to deal with it at the beginning. I read a lot about toolchains but still don’t know enough to explain details. I think that best answers are in crosstool-ng documentation....

So I decide to check what is going on with crosstool-ng and refresh my old post about building arm-unknown-linux-gnueabi toolchain. Last post was pretty popular, so definitely this is direction I should follow :). I will not repeat myself, so if you encounter any problems please check last post, section with known problems in crosstool-ng doc/ directory or RTFM.

Unfortunately after few tries of cross compiling eglibc using different source for instructions I alway end with hard to solve issues. Luckily, in the sources of eglibc I noticed instructions for cross-compiling written long time ago by Jim Blandy(I know i should start here). Lot of thanks to him for it. Below I describe my experience which I gained during eglibc cross compilation for arm-unknown-linux-gnueabi and procedure that I used. Commands below contain some constants that I used in previous works....

Quick build of arm-unknown-linux-gnueabi with crosstool-ng

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....
