It would otherwise result into undefined referenecs for some functions
in the base when using the gold linker:
error: undefined reference to 'sqrt'
Fixes https://github.com/bos/double-conversion/pull/17
Previously ghc option -optl=-lm was used for packages depending on
such functions, but that could result into
fatal error: cannot mix -r with dynamic object /nix/store/7crrmih8c52r8fbnqb933dxrsp44md93-glibc-2.25/lib/libm.so.6
in some situations like profiling builds.
Patch was prepared by Michael Bishop and Niklas Hambüchen.
Closes https://github.com/NixOS/nixpkgs/pull/27584.
Packages get --host and --target by default, but can explicitly request
any subset to be passed as needed. See docs for more info.
rustc: Avoid hash breakage by using the old (ignored)
dontSetConfigureCross when not cross building
The approach taken to add this package was to port over the definitions
currently existing for HEAD, and making the necessesary changes to get
this building.
The Haskell package set associated with this compiler doesn't yet
guarantee that all or most of the packages successfully build with this
new compiler, but that will improve over time after this GHC 8.2.1
is officially released and the ecosystem catches up.
See previous commit for what was done to `binutils` to make this
possible.
There were some uses of `forcedNativePackages` added. The
combination of overrides with that attribute is highly spooky: it's
often important that if an overridden package comes from it, the
replaced arguments for that package come from it. Long term this
package set and all the spookiness should be gone and irrelevant:
"Move along, nothing to see here!"
No hashes should be changed with this commit
If the flag enableIntegerSimple is true GHC will be build with the GPL-free but
slower integer-simple library instead of the faster but GPLed integer-gmp
library.
The attribute `pkgs.haskell.compiler.integer-simple."${ghcVersion}"` provides a
GHC compiler build with `integer-simple`.
Similarly, the attribute `pkgs.haskell.packages.integer-simple."${ghcVersion}"`
provides a package set supporting `integer-simple`.
