This is useful for non-Autoconf-based packages, since GNU Make's
default for CXX is "g++". (The CC default is "cc" so should work fine
with Clang already.)
Some packages in the llvm suite (e.g. compiler-rt) cannot be built
separate from the build of llvm, and while some others (e.g. clang) can
the combined build is much better tested (we've had to work around
annoying issues before). So this puts llvm, clang, clang-tools-extra,
compiler-rt, lld, lldb, and polly all into one big build (llvmFull).
This build includes a static llvm, as dynamic is similarly less tested
and has known failures.
This also updates libc++ and dragonegg. libc++ now builds against
libc++abi as a separate package rather than building it during the
libc++ build.
The clang purity patch is gone. Instead, we simply set --sysroot to
/var/empty for pure builds, as all impure paths are either looked up in
the gcc prefix (which we hard-code at compile time) or in the sysroot.
This also means that if NIX_ENFORCE_PURITY is 0 then clang will look in
the normal Linux paths by default, which is the proper behavior IMO.
polly required an updated isl. When stdenv-updates is merged, perhaps we
can update the isl used by gcc and avoid having two versions.
Since llvm on its own is now separate from the llvm used by clang, I've
removed myself as maintainer from llvm and will leave maintenance of
that to those who are interested in llvm separate from clang.

Install names need to be absolute paths, otherwise programs that link
against the dylib won't work without setting $DYLD_LIBRARY_PATH. Most
packages do this correctly, but some (like Boost and ICU) do not.
This setup hook absolutizes all install names.
nix-prefetch-git does not convert relative submodule urls into absolute
urls based on the parent's origin. This patch adds support for
repositories which are using the relative url syntax.
All JARs in $pkg/share/java (for each $pkg in the build inputs) are
added to $CLASSPATH. Thus, you can say
buildInputs = [ setJavaClassPath someJavaDependency ];
and the JARs in someJavaDependency will be found automatically by
tools like javac or ant.
Note that the manual used to say that JARs should be installed in
lib/java; this is now share/java, following the Debian policy:
http://www.debian.org/doc/packaging-manuals/java-policy/x110.html
The directory share/java makes more sense because JARs are
architecture-independent. (Also, a quick grep shows that we were not
exactly consistent about this in Nixpkgs.)

This is necessary for some packages, like dns, because cabal warns about
multiple versions of the same dependency being used, but the usage is fine,
actually, so we want the build to succeed. Packages that depend on 'doctest'
also have this issue <https://github.com/sol/doctest-haskell/issues/69>.
Before this commit, if a haskell library X depends on Y, and X was added to
systemPackages, only X would be available in the user environment. Y
would not be avialable, which causes X to be broken. This commit solves
the issue by setting propagatedUserEnvPkgs to all packages X depends
on when X is a library.
This adds nix-run, which is a thin wrapper around nix-build.
nix-run calls nix-build, and then executes the resulting build.
If no executable artifact is built, nix-runs outputs an error
message.
myEnvRun calls myEnvFun and builds a script that directly runs
the load-env-* script.
Together, nix-run and myEnvRun allows you to set up an environment
that can be loaded in this way:
envs.nix:
{
gcc = myEnvRun {
name = "gcc";
buildInputs = [ gcc ];
};
}
$ nix-run -A gcc envs.nix
You end up directly in your environment without having to do
nix-env -i. You will always have a fresh environment and you
don't have to pollute you profile with a lot of env packages.
The nix-prefect git script was broken when trying to parse certain
groups of submodules. This patch fixes the url detection for submodule
repositories to use the more reliable `git config` commands.
* There now is full support for building Haskell packages as shared libraries
for GHC versions 7.4.2 or later. The Cabal builder recognizes the following
attributes:
- enableSharedLibraries configures Cabal to build of shared libraries in
addition to static ones. This option requires that all dependencies of
the package have been compiled for use in shared libraries, too.
- enableSharedExecutables configures Cabal to prefer shared libraries when
linking executables.
The default values for these attributes are arguments to the haskellPackages
expression.
* Haskell builds now run in a LANG="en_US.UTF-8" environment to avoid plenty
of build and test suite errors. Without this setting, GHC seems unable to
deal with the UTF-8 character encoding that's generally considered standard
in the Haskell world.
* The Cabal builder supports a new attribute 'testTarget' to specify the exact
set of tests to be run during the check phase.
* The ghc-wrapper attribute ghcVersion has been removed. Instead, we use the
ghc.version attribute, which exists in unwrapped GHC derivations, too.
The default target (i386-linux) causes flags like "-march i386" to be
added, which breaks on recent Fedora releases (18 and up), resulting
in errors like:
/usr/lib/gcc/i686-redhat-linux/4.7.2/../../../../include/c++/4.7.2/ext/atomicity.h:48: undefined reference to `__atomic_fetch_add_4'
So set the target to i686-linux.

We cannot pass the --{enable,disable}-executable-dynamic flags to GHC
versions prior to 7.4.x.
Building shared libraries via --{enable,disable}-shared is possible in theory
with GHC 6.12.x or later, but doesn't work in practice because our GHC 6.10.x
builds don't provide shared versions of their base libraries. This could
probably be fixed, but it's probably not worth the effort.
enableSharedLibraries configures Cabal to build of shared libraries. This
option requires that all dependencies of the package have been compiled
for use in shared libraries, too.
enableSharedExecutables configures Cabal to prefer shared libraries when
linking executables.
This patch partly fixes issue #1084.
Kept the old hacks where they don't break the build in case they things
they fix are still relevant.
I checked that the upgrade doesn't break:
1) Asymptote and EProver builds.
2) My XeLaTeX demo from configurations/ repository.
3) Some of my own files.
The upgrade fixes problems with simultaneous use of 3D and LaTeX labels
in Asymptote.
Please provide a test that worked previously and is broken now if you
need to revert this update or its parts.
The dns packages requires this feature, because it ships two test programs: one
of them requires network access (so we cannot run it), but the other test does
not. Setting testTarget appropriately allows us to run only one of the two
suites.
Haskell packages that contain non-ascii characters in their .cabal file
or somewhere else in their haddock documentation fail to compile under
nixpkgs and usually flagged with noHaddock = true. I wanted to do the
same for modularArithmentic, when I realized that we just have to set
the locale to some UTF-8 compatible locale in build-support/cabal to fix
this issue correctly.
Wheezy has been released on June 15th and on all mirrors the SHA256 hash
of Packages.bz2 has changed to reflect the new release, so let's update.
Here is the release announcement from Debian:

It also seems that the versioning scheme has changed in version 7.x, so
they seem to have switched to a two digit versioning scheme. This means,
that the attribute name "debian70..." should really be something like
"debian7...", but I'm keeping the attribute as-is to not break
references.

9p (with caching enabled) is much faster than CIFS and doesn't require
Samba or virtual networking. For instance, building GNU Hello with
CIFS takes ~323s on my laptop, but with 9p it takes 54s.
More measurements will be needed to see if "cache=fscache" is really
faster than "cache=loose" (the former seems to be a little bit
faster).
