We can't run the checkPhase when build != host, so we may as well make
the checkInputs native.
This signicantly improves the situation of Python packages when enabling
strictDeps.
Modifies the build process of the manual to invoke nixdoc
automatically to generate XML files with function documentation.
Currently documentation is present for five of the files in `lib/`.
To add another file to the generated docs, both
`doc/functions/library.xml` and `doc/lib-function-docs.nix` must be
updated.
Since Intel's default openmp implementation is available in the same src
tarball, we can just include it in the package. This means that `mkl` now "just
works" without any environment variables, fragile setup-hooks, or forced
propagation.
Since the openmp implementation is only needed at runtime (and for test cases),
users can substitute a different one if they prefer by exporting it with
`LD_PRELOAD`, which is how Intel recommends handling this. If they do not do so,
`libiomp.so` lives next to `libmkl_rt.so` and thus will be in the RPATH as a
sane default.
Since this still comes from the same src tarball, we can ship it without losing
the fixed-output derivation; likewise, since Hydra is not building or caching
these, shipping these proprietary packages costs no bandwidth for the nix
community.
To make updating large attribute sets faster, the update scripts
are now run in parallel.
Please note the following changes in semantics:
- The string passed to updateScript needs to be a path to an executable file.
- The updateScript can also be a list: the tail elements will then be passed
to the head as command line arguments.
Encouraging to put container elements on their own lines to minimize
diffs, merge conflicts and making re-ordering easier.
Nix doesn't suffer the restrictions of other languages where commas are
used to separate list items.
First of all, this makes the existing documentation a bit more clear on
what autoPatchelfHook is all about, because after discussing with
@svanderburg - who wrote a similar implementation - the rationale about
autoPatchelfHook wasn't very clear in the documentation.
I also added the recent changes around being able to use autoPatchelf
manually and the new --no-recurse flag.
