#15122: Compiling a library problem with a local 8.5 build -------------------------------------+------------------------------------- Reporter: fmixing | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: 8.6.1 Component: Compiler | Version: 8.5 Keywords: | Operating System: MacOS X Architecture: x86_64 | Type of failure: GHC rejects (amd64) | valid program Test Case: | Blocked By: Blocking: | Related Tickets: Differential Rev(s): | Wiki Page: -------------------------------------+------------------------------------- I’ve discovered that one library throws type checking exception when I try to compile it with my version of ghc compiler (I build it using `cabal new-build --with-compiler=/usr/local/bin/ghc-8.5.20180504`, the compiler was built from the master with 56974323ed427988059b5153bb43c694358cbb9b as the last commit), but it builds with 8.4.2 compiler (cabal new-build --with-compiler=/usr/local/bin/ghc-8.4.2). It’s really strange, so I tried to `make` the local version of 8.4.2 in the branch ghc-8.4.2-release, and found out that it cannot be built because there are missing some files that are necessary for build. So maybe I’m doing something wrong? And can it be that this library doesn’t type check with 8.5 because it’s built from source files?
