[Cross-compilation] How can I port coreutils and bash/dash ?

[fiveayem]

Hello,

Having ported Newlib (and built a specific toolchain) for my OS, I would now like to port some GNU binaries, such as coreutils and bash. However, I am not a specialist about cross-compilation, and this is the reason why I ask for your help. I know that it is necessary to execute a configure script before "making". But which parameters should I provide the script with ?

Sorry if my question seems stupid, but I am not an expert at all. If bash is too complicated to deal with, maybe you could tell me about how porting dash ? I have heard that it is much easier, but I do not know where to find the source code.

Thanks a lot for your help.

Dash Shell.

Ok, thanks

And what about the procedure for porting ?

Homework: RTFM

Code: Select all

./configure --help

This worked for me for both dash and coreutils.

Code: Select all

./configure --host=x86_64-myos --prefix=/Users/gerryg/myos/
make

I haven't tried bash.

I used newlib as my C library but needed to add about 60 extra functions to it to get dash working. Even more for coreutils.
