# `cross-gnu`
[[Thomas_Schwinge|tschwinge]] has written a shell script for building a
complete cross-build environment for GNU/Hurd systems.
For now, find the shell scripts at
<http://nic-nac-project.de/~schwinge/tmp/cross-gnu> and
<http://nic-nac-project.de/~schwinge/tmp/cross-gnu-env>.
## Using
Read through it. Understand it. Then use it.
/!\ Be made aware that -- while it is of course possible to build a working
cross-compiler -- this is not trivial to do. You'll have to patch several of
the source packages. See the corresponding Debian unstable source packages
about which Hurd-specific patches exist and check which of them are not yet in
the upstream source packages. Not all of the patches from the Debian packages
are needed for getting a functional tool chain, though. Applying patches is
definitely needed for the glibc, Hurd and GCC source packages, as there are a
bunch of outstanding patches that are needed for getting a functional build.
### Supported Versions of Source Packages
The following ones are known to work. Others may work as well, but no
guarantee is given. Always the preferred version is listed first.
* `src/binutils`: [GNU Binutils](http://www.gnu.org/software/binutils/)
* CVS `binutils-2_18-branch`
$ cvs -d:pserver:anoncvs@sources.redhat.com:/cvs/src \
co -r binutils-2_18-branch binutils
$ mv src binutils-2_18-branch
* The 2.18 release tarball from <ftp://ftp.gnu.org/gnu/binutils/> should
also be fine, as should be all other recent releases.
* `src/gcc`: [GNU Compiler Collection](http://gcc.gnu.org/)
* SVN `gcc-4_1-branch`
$ svn co svn://gcc.gnu.org/svn/gcc/branches/gcc-4_1-branch
* Recent releases of the 4.1 series from <ftp://ftp.gnu.org/gnu/gcc/>
should also be fine.
Support for the 4.2 series (`gcc-4_2-branch`) and the upcoming 4.3 series
(`trunk`) is being worked on.
<!--
* SVN `gcc-4_2-branch` plus patches.
$ svn co svn://gcc.gnu.org/svn/gcc/branches/gcc-4_2-branch
TODO. patches: libiberty (?!), config.
For building recent version of GCC (e.g., the upcoming 4.3) you'll need to
have development packages of GMP and MPFR (for the *build* system)
installed.
-->
* `src/gnumach`: [GNU Mach](http://hurd.gnu.org/)
* CVS `gnumach-1-branch`
$ cvs -d:pserver:anoncvs@cvs.gnu.org:/cvsroot/hurd \
co -r gnumach-1-branch gnumach
$ mv gnumach gnumach-1-branch
* `src/mig`: [GNU Mach Interface Generator](http://hurd.gnu.org/)
* CVS `HEAD`
$ cvs -d:pserver:anoncvs@cvs.gnu.org:/cvsroot/hurd co mig
* `src/hurd`: [GNU Hurd](http://hurd.gnu.org/)
* CVS `HEAD`
$ cvs -d:pserver:anoncvs@cvs.gnu.org:/cvsroot/hurd co hurd
* `src/glibc`: [GNU C Library](http://www.gnu.org/software/libc/)
* CVS `glibc-2_7-branch`
$ cvs -d:pserver:anoncvs@sources.redhat.com:/cvs/glibc \
co -r glibc-2_7-branch glibc
$ mv libc glibc-2_7-branch
* TODO. Patches.
* Recent releases of the 2.7 series from <ftp://ftp.gnu.org/gnu/glibc/>
should also be fine, but need the same set of patches as the
`glibc-2_7-branch` needs.
<!--
* CVS `HEAD`
$ cvs -d:pserver:anoncvs@sources.redhat.com:/cvs/glibc \
co glibc
$ mv libc glibc-HEAD
* TODO.
<http://lists.gnu.org/archive/html/bug-hurd/2007-11/msg00026.html>
-->
<!--
* `src/gdb`: [GNU Debugger](http://www.gnu.org/software/gdb/)
This is optional and will only be compiled if present.
* CVS `gdb_6_6-branch`
$ cvs -d:pserver:anoncvs@sources.redhat.com:/cvs/src \
co -r gdb_6_6-branch gdb
$ mv src gdb_6_6-branch
Also needs some patch because of MIG changes, if I remember correctly.
* Recent tarballs from <ftp://ftp.gnu.org/gnu/gdb/> should also work.
