#13978: oddness surrounding aeson 1.0.2.1 on Debian -------------------------------------+------------------------------------- Reporter: clint | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 8.0.2 Keywords: | Operating System: Unknown/Multiple Architecture: | Type of failure: None/Unknown Unknown/Multiple | Test Case: | Blocked By: Blocking: | Related Tickets: Differential Rev(s): | Wiki Page: -------------------------------------+------------------------------------- per bgamari's request, I am filing this ticket as part of an ongoing plea for help to figure out what is going on. When building aeson 1.0.2.1 on Debian, we get a failure (https://buildd.debian.org/status/fetch.php?pkg=haskell- aeson&arch=amd64&ver=1.0.2.1-2&stamp=1499701762&raw=0) building the testsuite: {{{ [19 of 19] Compiling Data.Aeson.TH ( Data/Aeson/TH.hs, dist- ghc/build/Data/Aeson/TH.p_o ) Preprocessing test suite 'tests' for aeson-1.0.2.1...

Building the testsuite with -O0 causes it to fail with a different symbol. Building aeson with cabal (modulo having to hand-edit tests/Instances.hs to remove the redundant Tagged instance) results in a successful build of the testsuite. However, if I '''cabal configure --enable-tests --enable- library-profiling''' instead of just '''cabal configure --enable-tests''', then the build fails with {{{ [10 of 20] Compiling Data.Aeson.Internal ( Data/Aeson/Internal.hs, dist/build/Data/Aeson/Internal.o ) [11 of 20] Compiling Data.Aeson.Encoding.Builder ( Data/Aeson/Encoding/Builder.hs, dist/build/Data/Aeson/Encoding/Builder.o ) [12 of 20] Compiling Data.Aeson.Encoding.Internal ( Data/Aeson/Encoding/Internal.hs, dist/build/Data/Aeson/Encoding/Internal.o ) [13 of 20] Compiling Data.Aeson.Encoding ( Data/Aeson/Encoding.hs, dist/build/Data/Aeson/Encoding.o ) [14 of 20] Compiling Data.Aeson.Types.ToJSON ( Data/Aeson/Types/ToJSON.hs, dist/build/Data/Aeson/Types/ToJSON.o ) [15 of 20] Compiling Data.Aeson.Types.Class ( Data/Aeson/Types/Class.hs, dist/build/Data/Aeson/Types/Class.o ) [16 of 20] Compiling Data.Aeson.Types ( Data/Aeson/Types.hs, dist/build/Data/Aeson/Types.o ) [17 of 20] Compiling Data.Aeson.Text ( Data/Aeson/Text.hs, dist/build/Data/Aeson/Text.o ) [18 of 20] Compiling Data.Aeson ( Data/Aeson.hs, dist/build/Data/Aeson.o ) [19 of 20] Compiling Data.Aeson.Encode ( Data/Aeson/Encode.hs, dist/build/Data/Aeson/Encode.o ) [20 of 20] Compiling Data.Aeson.TH ( Data/Aeson/TH.hs, dist/build/Data/Aeson/TH.o ) [ 1 of 20] Compiling Data.Aeson.Types.Internal ( Data/Aeson/Types/Internal.hs, dist/build/Data/Aeson/Types/Internal.p_o ) Data/Aeson/Types/Internal.hs:67:1: error: Failed to load interface for `Prelude.Compat' Perhaps you haven't installed the profiling libraries for package `base-compat-0.9.3'?
