Hi Shikhar,
https://build.opensuse.org/project/show/home:ShikharJ:HaskellUpdate
the semigroups.cabal [1] file specifies different sets of dependencies depending on which version of GHC compiles the package. A (simplified) snippet of the file reads: | library | -- legacy configuration | if impl(ghc < 7.11.20151002) | build-depends: binary | build-depends: tagged >= 0.4.4 && < 1 | build-depends: text >= 0.10 && < 2 | build-depends: hashable >= 1.1 && < 1.3 | build-depends: unordered-containers >= 0.2 && < 0.3 | build-depends: transformers >= 0.2 && < 0.6 | , transformers-compat >= 0.5 && < 1 You compile with GHC 7.10.3, so in your configuration these settings are in effect. Your semigroups.spec file, however, comes from Factory -- which has GHC 8.4.3 -- and the build does not depend on those packages there (because they were merged into GHC's core libraries and are now all part of 'base'). Therefore, the semigroups.spec file in Factory does not list any of those packages as a dependency. If you want to generate a spec file that works properly with GHC 7.10.3, then you can install cabal2spec [2], download the cabal file from [1], and run: $ cabal2spec --compiler=ghc-7.10.3 semigroups.cabal That gives you a "semigroups.spec" with all necessary dependencies included.
