* let's try 2.0 version now, no time better than the present! Maybe!
* bz2 -> xz
* maybe python3
* disable pyGtkGlade for deps, maybe not needed?
* fix gtk/etc deps, deluge-gtk works! \o/
* restore installation of images and such
The old version is kept available as some torrent trackers have not
updated their whitelists yet.
This partially reverts commit cc03fb4210.
The libtorrentRasterbar update broke deluge 1.x, the hash was not
updated and obsolete dependencies and flags were not removed.
This makes packages use lapack and blas, which can wrap different
BLAS/LAPACK implementations.
treewide: cleanup from blas/lapack changes
A few issues in the original treewide:
- can’t assume blas64 is a bool
- unused commented code
This is based on previous work for switching between BLAS and LAPACK
implementation in Debian[1] and Gentoo[2]. The goal is to have one way
to depend on the BLAS/LAPACK libraries that all packages must use. The
attrs “blas” and “lapack” are used to represent a wrapped BLAS/LAPACK
provider. Derivations that don’t care how BLAS and LAPACK are
implemented can just use blas and lapack directly. If you do care what
you get (perhaps for some CPP), you should verify that blas and lapack
match what you expect with an assertion.
The “blas” package collides with the old “blas” reference
implementation. This has been renamed to “blas-reference”. In
addition, “lapack-reference” is also included, corresponding to
“liblapack” from Netlib.org.
Currently, there are 3 providers of the BLAS and LAPACK interfaces:
- lapack-reference: the BLAS/LAPACK implementation maintained by netlib.org
- OpenBLAS: an optimized version of BLAS and LAPACK
- MKL: Intel’s unfree but highly optimized BLAS/LAPACK implementation
By default, the above implementations all use the “LP64” BLAS and
LAPACK ABI. This corresponds to “openblasCompat” and is the safest way
to use BLAS/LAPACK. You may received some benefits from “ILP64” or
8-byte integer BLAS at the expense of breaking compatibility with some
packages.
This can be switched at build time with an override like:
import <nixpkgs> {
config.allowUnfree = true;
overlays = [(self: super: {
lapack = super.lapack.override {
lapackProvider = super.lapack-reference;
};
blas = super.blas.override {
blasProvider = super.lapack-reference;
};
})];
}
or, switched at runtime via LD_LIBRARY_PATH like:
$ LD_LIBRARY_PATH=$(nix-build -E '(with import <nixpkgs> {}).lapack.override { lapackProvider = pkgs.mkl; is64bit = true; })')/lib:$(nix-build -E '(with import <nixpkgs> {}).blas.override { blasProvider = pkgs.mkl; is64bit = true; })')/lib ./your-blas-linked-binary
By default, we use OpenBLAS LP64 also known in Nixpkgs as
openblasCompat.

This closes #79441.
ghcWithPackages is using `ghc-pkg recache` to build its package
database. By doing so, it overrides the `package.cache[.lock]` files.
Details are unclear, but GHC 8.10 changed a bit the behavior.
Previously, it was unconditionally replacing the files by new ones. Now
it tries to open (for modification) the files. These files are symlinks
to another nix derivation, which is hence read-only.
This commit removes the files before running `ghc-pkg recache`, hence it
will just write the new files.
Tested with `haskellPackages.ghcWithPackages` (i.e. GHC 8.8) and
`haskell.packages.ghc8101.ghcWithPackages` (i.e GHC 8.10) with the
following nix file, at the root of the nixpkgs repository:
```
with import ./. {
overlays = [
(
self: super: {
haskellPackages = super.haskell.packages.ghc8101.override {
overrides = selfh: superh: {
th-lift-instances = super.haskell.lib.doJailbreak superh.th-lift-instances;
th-expand-syns = super.haskell.lib.doJailbreak superh.th-expand-syns;
th-reify-many = super.haskell.lib.doJailbreak superh.th-reify-many;
th-orphans = super.haskell.lib.doJailbreak superh.th-orphans;
haskell-src-meta = super.haskell.lib.doJailbreak superh.haskell-src-meta;
};
};
}
)
];
};
haskellPackages.ghcWithPackages(p:[p.PyF])
```
This will test with GHC 8.10. Comment out the `overlays` to test with
GHC 8.8.
