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. My build system parameters: Debian GNU/Linux wheezy/sid 3.2.0-2-amd64
- Clone crosstools-ng (you need mercurial)
|
|
- Create temporary directory and run
|
|
- We probably want to change directory to which all stuff will be build (default
is
$HOME/x-tools):
|
|
And go to:
Paths and misc options ---> (${HOME}/x-tools/${CT_TARGET}) Prefix directory
Change it according to your needs. Exit end save configuration.
- Build (number after dot depend on how many command we want to run
simultaneously):
ct-ng build.4It can take a lot of time. On my machine with 5k BogoMips it takes over 1h.
Problems that you can encounter
-
gcj- latest changeset2916:6f758ed4c0b9have trouble findinggcjbinary, which it show using following message:[ERROR] Missing: ‘x86_64-unknown-linux-gnu-gcj’ or ‘x86_64-unknown-linux-gnu-gcj’ or ‘gcj’ : either needed! To workaround this install
gcj and link binary like this:
|
|
duma- mentioned changeset also has problem with url to D.U.M.A library, apply below changes to workaround problems:
|
|
-
mawk- if mawk return syntax error like this:mawk: scripts/gen-sorted.awk: line 19: regular expression compile failed (bad class – [], [^] or [)
It could be fixed in two ways. First is to change line 19 in
/path/to/tmp/dir/.build/src/glibc-2.9/scripts/gen-sorted.awk Is:

Or simply by installing gawk, reconfigure and recompile crosstools-ng. This
was my first post related to linux embedded environment. Hope it will be more.
Enjoy!
