Stdenv adapters are kinda weird and un-idiomatic (especially when they
don't actually change stdenv). It's more idiomatic to say
buildInputs = [ makeCoverageAnalysisReport ];
This removes the need for hacks like stdenv.regenerate. It also
ensures that overrideGCC is now stackable (so ‘stdenv = useGoldLinker
clangStdenv’ works).
setup.sh uses the anti-pattern `for f in $(find ...); do` in several
places. `find` returns one path per line, but `for` splits its arguments
by words, so paths which contain spaces are incorrectly split! The
correct way is `find ... | while read f; do`
Binutils nowadays contains ld.gold, which depends on libstdc++. So it
needs to be built with the new GCC rather than the one from
bootstrap-tools.
Issue #1469.
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.
The function ‘mkDerivation’ now checks whether the current platform
type is included in a package's meta.platform field. If not, it
throws an exception:
$ nix-build -A linux --argstr system x86_64-darwin
error: user-thrown exception: the package ‘linux-3.10.15’ is not supported on ‘x86_64-darwin’
These packages also no longer show up in ‘nix-env -qa’ output. This
means, for instance, that the number of packages shown on
x86_64-freebsd has dropped from 9268 to 4764.
Since meta.platforms was also used to prevent Hydra from building some
packages, there now is a new attribute meta.hydraPlatforms listing the
platforms on which Hydra should build the package (which defaults to
meta.platforms).
meta.license is can be a string or a list of strings. But there is one
unhandled case where "unfree" (or "unfree-redistributable") is a part of
a list. It will currently not be detected as an "unfree" package and
Hydra will attempt to build it. This should fix it.
Example: http://hydra.nixos.org/build/6553461
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
Since nix-1.4, nix's corepkgs contain a fetchurl suitable for
downloading the bootstrap binaries. Doing this will allow us to have a
nixpkgs with no in-tree binaries without breaking the purity of the
bootstrap (though for now, they are fetched in-tree until the binaries
are added to nixos.org somewhere). As an additional small benefit, the
in-tree binaries do not have to be hashed on every instantiation as they
do now.
The fetchurl in nix-1.2 and 1.3 isn't able to make binaries executable,
so it can't be used for this case. In that case, attempting to build the
bootstrap will show a message asking the user to manually download each
file and add it to the store with nix-store --add (but the hash is
ultimately the same, of course).
