[nslu2-linux] Re: Building a cross compiler for SlugOSBE-5.3-beta

 

I don't know why you want to use crosstool for slugos5be toolchain.

SlugOS5BE has its proven way of building toolchain (Openembedded and bitbake), optware just uses the resulting toolchain.

For a new platform that you want to build toolchain from scratch, you should look at crosstool-ng.

I had a couple of issues with glibc requiring optimization which I fixed with a hack to crosstool.sh and crosstool.mk.
