My idea is to provide special stdenv expressions that will contain in the path
additional cross compilers. As most expressions for programs accept a stdenv parameter,
we could substitute this parameter with the special stdenv, which will have a
generic builder that attempts the usual "--target=..." and can additionally
have an env variable like "cross" with the target architecture set.
So, finally we could have additional expressions like this:
bashRealArm = makeOverridable (import ../shells/bash) {
inherit fetchurl bison;
stdenv = stdenvCross "armv5tel-unknown-linux-gnueabi";
};
Meanwhile it does not work - I still cannot get the cross-gcc to build.
I think it does not fill the previous expressions with a lot of noise, so I
think it may be a good path to follow.
I only touched some files of the current stdenv: gcc-4.3, kernel headers
2.6.28, glibc 2.9, ...
I tried to use the gcc-cross-wrapper, that may be very outdated. Maybe I will
update it, or update the gcc-wrapper expression to make it fit the cross tools,
but meanwhile I even cannot build gcc, so I have not tested the wrapper.
This new idea on cross compiling is not similar to that of the
nixpkgs/branches/cross-compilation, which mostly added bare new expressions for
anything to be cross compiled, if I understood it correctly.
I cared not to break anything of the usual stdenv in all this work.

This comes from:
svn diff ^/nixpkgs/trunk/@18255 ^/nixpkgs/branches/stdenv-updates/ > diff
patch -p0 < diff
and then adding into svn all files new from the patch.
trunk@18255 comes from the last time I updated stdenv-updates from trunk.

Redland's use of the pre-processor symbol SQLITE_API collides with a
symbol of the same name in sqlite 3.6.19. Patching the source code to
use REDLAND_SQLITE_API instead works around the problem.

Sqlite has a build mode called "amalgamation" that gathers all 90+ source code
files into a single sqlite3.c file before compiling the library. Building
sqlite this way reportedly gives a 5-10% performance gain because the compiler
can perform more sophisticated optimizations.
svn path=/nixpkgs/trunk/; revision=18092
The new version requires Tcl at build time in order to construct sqlite3.h,
even when the --without-tcl option is passed to configure. That feels odd
because the sqlite web site does advertise "no dependencies", but then it's
probably not a big deal either. The build of the Tcl plugin for sqlite is still
disabled, so there is no run-time dependency.

propagatedBuildInputs, because those inputs are required by the *.pc
or *.la files of the package:
- If a *.pc file references a non-propagated input, then Gnome
packages have the bad tendency to silently ignore this problem in
configure scripts - the failure of a command like `pkg-config
--cflags foo' will be ignored if a dependency of foo.pc is
missing, so no flags will be added, and the build will fail later
on a missing header or library.
- If a *.la file references a non-propagated input, the build will
also fail, because Libtool will add library dependencies that it
cannot find. (Arguably *.la files should never reference packages
that aren't in the corresponding *.pc file, but they do it
anyway).
By setting the propagatedBuildInputs properly, it should be possible
to get rid of all the NIX_CFLAGS_COMPILE / NIX_LDFLAGS hacks in the
Gnome expressions.

* Dropped "nolongdouble.patch". The patch no longer applies to Python 2.6, and
apparently isn't required anymore either.
* Added access to native Darwin arch utility. Python tries to run 'arch' in
the configure stage, but that binary reside in /usr/bin. To make it
available to the expression, the small wrapper darwinArchUtility is added as
a buildInput if appropriate.
* Don't pass --enable-shared. The build fails if we try to enable building of
shared libraries, apparently because some required libraries aren't linked,
i.e. the linker call isn't right.
TODO:
* Figure out how to enable shared linking.
* The resulting binary on Darwin seem to lack the binascii module.

The initial MacOS X binaries have been linked to libgmp.dylib using some
mad path in /opt that's now hard-coded into the program. Consequently,
$DYLD_LIBRARY_PATH must contain the place where libgmp really is for
those binaries to run correctly. Tested on i386-apple-darwin9.7.0.

On MacOS X, we used to use the native perl interpreter from /usr/bin.
Unfortunately, that interpreter fails to build a number of packages
(Subversion, Git, etc. ...), because it assumes knowledge about the
underlying C compiler that is not valid for the compiler used by Nix.
For example, /usr/bin/perl assumes that the compiler can build binaries
for both the ppc and the x86 architecture. /usr/bin/gcc can do that, but
the gcc from Nix can't.
The solution is to compile Perl 5.10 in Nix so that the ./configure
phase can properly detect the system's capabilities. However, note that
the resulting binary is impure: it will find headers in /usr/include and
libraries in /usr/lib. In this respect, the Nix-compiled perl binary is
no different than the native one in /usr/bin -- it's just configured
more accurately.
