Hi!
I'm working on getting a compiler-farm up, that can cross compile to
multiple platforms. It's allready almost done, but there are some small
problems left over.
Since the Compiler-Farm will only compile (no preprocessing, no linking,
etc.) because of usage of DISTCC, i wanted to ask if there is a way to
build binutils/gcc in a way that there are only the really necessary
parts (as, gcc, g++) without support for linking and other unwanted
stuff.
Just leave the build when it stops! It stops when trying libgcc, so if
you don't link,
where you will need libgcc?
The second problem is, how to find out what to put in the sysroot
packages used to bootstrap the crossc ompilers for each platform. At the
moment this is a really annoying manual process of sorting out and
tar'ing together /usr/include and /usr/lib with some additional
softlinks. Is there a somewhat short list of files i need for this
purpose?
You don't need anything for the $target system...
The sysroot package is used only for bootstrapping gcc, since everything
that the cross-gcc will see is preprocessed allready.
No 'bootstrap' required either...
In a nutshell: Building GCC binaries requires ONLY the $host GCC !
Nothing for
the $target ! Producing anything for the $target WITH the new GCC then
can require
quite a lot $target stuff !
