Dear Gershom / GHC development team,

The provided windows version of GHC contains lib-gmp.
Hence, this version enforces a LGPL license on my code
 (see e.g. https://gitlab.haskell.org/ghc/ghc/wikis/replacing-gmp-notes for more info) .
Unfortunately, this license is unacceptable for me.

For me this raises the question: What is the strategy of GHC with respect to licensing?
In particularly,
* Why considers GHC a LGPL license for all the code developed by their users acceptable?
* Is GHC considering to allow their user to standardly develop their code under a license of their own choice?
* Are there plans to offer the GHC users an opportunity to choose the license in the near future?
   e.g. by distributing GHC binary distributions with integer-gmp and integer-simple.

Thanks in advance for your answers,

Pierre van de Laar

On behalf of the Haskell Platform team, I'm happy to announce the release of

Haskell Platform 8.6.5

Now available at


This includes GHC 8.6.5, cabal-install, and stack 1.9.3.

It is an incremental release over 8.6.3 intended mainly to make available bugfixes for windows in subsequent revisions in the 8.6 series and otherwise leave everything the same. These windows fixes are important, and it is recommended all windows users upgrade to
8.6.5 whether through the platform installer or some other mechanism.

For detail on these changes and fixes see

As with the 8.6.3 release, we are only providing core builds. Further, in 8.6.3 we moved from generic linux installers to recommending users install ghc through ghcup. As discussed in the last announcement, we have now moved to recommending os x users also use ghcup rather than a dedicated binary installer. For more details, please see the 8.6.3 announcement at

Happy Haskell Hacking all,
