Updating the cross-build expressions, adding some flexibility.
Updated the linux headers used cross building, as 2.6.28 had bugs on endianness in
sparc64.
There were, as usual some bugs in gcc. Maybe not many make a cross compiler to
ultrasparc.
For the record, I could build an ultrasparc kernel with this base nix:
import /etc/nixos/nixpkgs/default.nix # The root nixpkgs default.nix
{
crossSystem = {
config = "sparc64-unknown-linux";
bigEndian = true;
arch = "sparc64";
float = "soft";
withTLS = true;
cpu = "ultrasparc";
};
config = pkgs: {
packageOverrides = pkgs : {
platform = {
name = "sparc64";
kernelHeadersBaseConfig = "sparc64_defconfig";
kernelBaseConfig = "sparc64_defconfig";
kernelArch = "sparc";
kernelAutoModules = false;
kernelTarget = "zImage";
uboot = null;
};
};
};
}
Although it did not boot directly in qemu-system-sparc64:
[sparc64] Kernel already loaded

- Adding ghdl with gcc 4.4 (with a patch I built for it to work)
- Adding me as maintainer to both gccs and ghdl
svn path=/nixpkgs/branches/stdenv-updates/; revision=19475
Some things don't work:
- The ghdl expression (it still needs the gcc 4.3.4 src, ...)
- The gnat wrappers need to be more generic - now they work only for the
given gnatboot (taken from gentoo) and gnats installed to their $out
store path.
- Using the cloogppl and ppl. We will need our own gnatboot built with c++
libraries for that.

the target libraries, as 4.3.4
I trigger the breaking build using uclibc, instead of glibc, and then the
mixture of CPP getting the build glibc headers, and CC getting the uclibc
headers, makes the problem evident.
In 4.3.4 it only affected libmudflap. In 4.4.2, it affects libmudflap and
libstdc++.

through libtool.
I found a make variable holding flags that will not be trimmed by libtool:
FLAGS_FOR_TARGET.

Dealt with the gcc 4.4 expression for it to work well for a native and a cross
compiler, adding a pair of patches to get the job done without much side
effects. One (libtool problems on -B) comes from the gcc 4.3 expression, while
the other fixes a bug already fixed in gcc 4.4.3.

used to cross-compile, because of some bug in 4.4.2 I think. This bug does not
allow building a cross-compiler without libc:

Maybe we should wait for 4.4.3 or stay with 4.4.1 cross compiling. By now I
will keep 4.3.4 on cross compilation.

Fixing the glibc-2.10 expression on cross-builds (which should be ported to
the glibc-2.11 expression once we get "ports" there)
Making kde3 and cyrus-sasl use gcc-4.3, because the strictness in gcc-4.4 does
not allow them build.
