Treating fixupPhase specially is really ugly. Also, it collides with
the work in the multiple-outputs branch (which already has support for
fixing up all outputs).
Partial revert of 0a44a09121.
Some programs, e.g. guile-config, has a shebang that ends in '\':
#!/usr/bin/guile-1.8 \
-e main -s
!#
;;;; guile-config --- utility for linking programs with Guile
;;;; Jim Blandy <jim@red-bean.com> --- September 1997
This currently breaks patchShebangs:
$ read oldPath arg0 args <<< 'shebang \'; echo $?
1
$ echo $oldPath
shebang
$ echo $arg0
$ echo $args
(And setup.sh/patchShebangs is run with 'set -e' so any command that
return non-zero aborts the build.)
Fix by telling 'read' to not interpret backslashes (with the -r flag):
$ read -r oldPath arg0 args <<< 'shebang \'; echo $?
0
$ echo $oldPath
shebang
$ echo $arg0
\
$ echo $args
Also needed: escape the escape characters so that sed doesn't interpret
them.
patchShebangs has a bug that shows itself on files that have the
executable bit set but have no shebang (i.e. a blank/empty first line).
The shell would then evaluate this:
if [ != '#!' ]; then
# not evaluated
fi
With proper quoting we get the correct behaviour:
if [ "" != '#!' ]; then
# this will be evaluated
fi
When building e.g. perl for the first time there is no perl in PATH yet,
so command -v perl will fail.
This brings back the previous behaviour of silently not patching
shebangs for which there is no available command in PATH.
Currently "/usr/bin/env python" is rewritten to "/nix/store/.../env
python". That doesn't really improve anything because the interpreter
still have to be located in $PATH at runtime. The result is that many
nix package expressions do .../bin/env fixup themselves.
Instead of everyone having to do this patching locally, add the
functionality to the standard environment patchShebangs function so that
everyone can benefit.
set CMAKE_LIBRARY_PATH, CMAKE_INCLUDE_PATH based on NIX_CFLAGS_COMPILE and
NIX_LDFLAGS so that cmake's find_library like functions find all the libraries
gcc knows about thanks to the gcc wrapper
This is particular useful with myEnvFun which then also sets those CMAKE_* env
variables.`
Because setup.sh has to change this causes many rebuilds - thus it should be
included in a stdenv-update like branch
Also cmake builds in parallel perfectly fine
update cmake to latest minor number, I didn't change the patches,
just reapplied them manually recordin a new patch
I'm not sure whether this was by intention, but so far postPatch hooks were
silently skipped whenever the patches list was empty. This change could possibly
change the build results of the following packages:
* gcc
* cmake (264)
* systemtap
* quemu-kvm
These packages all have in common that they have a postPatch hook and the
patches list can be empty when certain conditions are met.

This is for consistency with terminology in stdenv (and the terms
"hostDrv" and "buildDrv" are not very intuitive, even if they're
consistent with GNU terminology).
This allows various applications. It allows users to set global
optimisation flags, e.g.
stdenv.userHook = ''NIX_CFLAGS_COMPILE+=" -funroll-loops"'';
But the impetus is as an alternative to issue #229, allowing impure
stdenv setup for people who want to use distcc:
stdenv.userHook = "source /my/impure/setup-script.sh";
This is probably a bad idea, but at least now it's a bad idea in
people's configuration and not in Nixpkgs. :-)

uncommon command so it was a headache during the bootstrap.

These markers follow the format of those of `nix-store --print-build-trace',
which allows extraction of, say, phase durations in a similar way.

If a build expressions has set "enableParallelBuilding = true", then the
generic builder may utilize more than one CPU core to build that particular
expression. This feature works out of the box for GNU Make. Expressions that
use other build drivers like Boost.Jam or SCons have to specify appropriate
flags such as "-j${NIX_BUILD_CORES}" themselves.

inputs did not get in)
Updating the xorg builder script to support cross building (in fact, support
for propagating the required build inputs).
svn path=/nixpkgs/branches/stdenv-updates/; revision=18569
- Before this changes, cflags and ldflags for the native and the cross compiler
got mixed. Not all the gcc-wrapper/gcc-cross-wrapper variables are
independant now, but enough, I think.
- Fixed the generic stdenv expression, which did a big mess on buildInputs and
buildNativeInputs. Now it distinguishes when there is a stdenvCross or not.
Maybe we should have a single stdenv and forget about the stdenvCross
adapter - this could end in a stdenv a bit complex, but simpler than the
generic stdenv + adapter.
- Added basic support in pkgconfig for cross-builds: a single PKG_CONFIG_PATH
now works for both the cross and the native compilers, but I think this
should work well for most cases I can think of.
- I tried to fix the guile expression to cross-biuld; guile is built, but not
its manual, so the derivation still fails. Guile requires patching to
cross-build, as far as I understnad.
- Made the glibcCross build to be done through the usage of a
gcc-cross-wrapper over the gcc-cross-stage-static, instead of using it
directly.
- Trying to make physfs (a neverball dependency) cross build.
- Updated the gcc expression to support building a cross compiler without getting
derivation variables mixed with those of the stdenvCross.

derivation, the "buildInputs" in every stdenv mkDerivation don't map now
directly to the environment
variable "buildInputs" in the builder, but "buildNativeInputs". So, the inputs
build by the native compiler.
When cross compiling, they will map to the environment variable "buildInputs"
(yes, now the same name), which means does to be built with the cross compiler.
I think I improved the naming of variables a bit. There was a big mess,
specially in the stdenv adapter for cross building, and also in the default
builder script.
I also tried to add proper manager of propagatedInputBuilds, these being
propagated considering the host or build origin of that input build (so, at the
end, being those propagatedInputBuilds being propagated properly to the native
or the cross compiler.

I made the stdenvCross adapter simpler, according to Nicolas Pierron comments,
and I commented it a bit.
There are still jobs to do. At least:
- Plan for the general renaming from buildInputs to hostInputs
- We should not break merges from trunk.
- Make the generic stdenv understand about host/buildInputs, at least for
native builds, because it is used in the always-native building of
stdenvLinux. This should allow us to remove all duplications of "*NoCross" in
nixpkgs.

you can't distinguish the two in (say) nix-store -qR.
* On x86_64-linux, put $out/lib64 in the RPATH in addition to
$out/lib, because some packages (in particular GCC) put libraries in

This has a major advantage: you can write hooks directly in Nix
expressions. For instance, rather than write a builder like this:
source $stdenv/setup
postInstall=postInstall
postInstall() {
ln -sf gzip $out/bin/gunzip
ln -sf gzip $out/bin/zcat
}
genericBuild
(the gzip builder), you can just add this attribute to the
derivation:
postInstall = "ln -sf gzip $out/bin/gunzip; ln -sf gzip $out/bin/zcat";
and so a separate build script becomes unnecessary. This should
allow us to get rid of most builders in Nixpkgs.
* Allow configure and make arguments to contain whitespace.
Previously, you could say, for instance
configureFlags="CFLAGS=-O0"
but not
configureFlags="CFLAGS=-O0 -g"
since the `-g' would be interpreted as a separate argument to
configure. Now you can say
configureFlagsArray=("CFLAGS=-O0 -g")
or similarly
configureFlagsArray=("CFLAGS=-O0 -g" "LDFLAGS=-L/foo -L/bar")
which does the right thing. Idem for makeFlags, installFlags,
checkFlags and distFlags.
Unfortunately you can't pass arrays to Bash through the environment,
so you can't put the array above in a Nix expression, e.g.,
configureFlagsArray = ["CFLAGS=-O0 -g"];
since it would just be flattened to a since string. However, you
can use the inline hooks described above:
preConfigure = "configureFlagsArray=(\"CFLAGS=-O0 -g\")";
