On GHC 9.2: Blocked on dependencies #468

Closed andreasabel closed 2 years ago

andreasabel commented 2 years ago

Seems like the dependency chain github -> tls -> memory -> basement is failing at its end:

$ cabal install github-0.27
Resolving dependencies...
Error: cabal: Could not resolve dependencies:
[__0] trying: github-0.27 (user goal)
[__1] trying: github:-openssl
[__2] trying: tls-1.5.5 (dependency of github -openssl)
[__3] trying: memory-0.16.0 (dependency of tls)
[__4] trying: memory:+support_foundation
[__5] trying: basement-0.0.12 (dependency of memory +support_foundation)
[__6] next goal: base (dependency of github)
[__6] rejecting: base-4.16.0.0/installed-4.16.0.0 (conflict: basement =>
base>=4.9 && <4.16)

Don't use -openssl. The +openssl configuration works well. (Problems with basement aren't my problems).

Thanks for the quick advice!

With flag openssl (not the default) it seems to fail at HsOpenSSL (>=0.11.4.16 && <0.12), via github -> HsOpenSSL/text/parsec (incompatible requirements on bytestring).

$ cabal install github-0.27 -f+openssl

Error: cabal: Could not resolve dependencies:

[__6] rejecting: base-4.16.0.0/installed-4.16.0.0 (conflict: parsec =>

The version of HsOpenSSL that is picked by cabal-install with GHC 9.2 on my system is 0.11.4.15 (excluded by github-0.27):

$ cabal install HsOpenSSL
Resolving dependencies...
Build profile: -w ghc-9.2.1 -O1
In order, the following will be built (use -v for more details):
 - network-2.5.0.0 (lib:network) (requires download & build)
 - HsOpenSSL-0.11.4.15 (lib:HsOpenSSL) (requires download & build)
((SUCCEEDS))
