Re: Need help with using crosstool to build toolchain for Au1550.

[Alexander Bigga - Software <linux at bigga dot de>]

Hello Anmol,

I think you're mixing two things: 

- crosstool by Dan Kegel http://www.kegel.com/crosstool/
- crosstool-ng (== "ct-ng", aka "next generation crosstool) by Yann E. MORIN 
  http://ymorin.is-a-geek.org/dokuwiki/projects/crosstool

For Au1550 you need an mipsel toolchain. So in crosstool-0.43 you have to
call ./demo-mipsel.sh. But you should change "RESULT_TOP" to
/home/anmol/opt/ and run the script as user.

(Ok, you may use Au1550 in big endian mode, but I have no experience with
it.)

Maybe you have a look at http://sourceforge.net/projects/xxsvideo. This
project uses crosstool and runs building toolchain for arm (default) and 
mipsel automatic. In the current SVN it uses optional crosstool-ng too.

This config for crosstool-ng. To use it, you have to checkout the SVN trunk
and then:

./configure --prefix=/home/anmol/opt/
make
make install
cp samples/mipsel-unknown-linux-gnu/crosstool.config .config
./ct-ng build

This should run. If not: write us or the mailinglist.


Best regards,

Alexander
