Hi! I'm trying to compile a dynamic executable in Debian on a x86_64 architecture with ghc 7.4.1-4 and ghc-dynamic installed. To compile the program I started from a clean cabal user database, set the 'shared' and 'executable-dynamic' settings to 'True' in cabal conf and fired away with 'cabal install' in my package's directory. It compiled all the libraries fine-- both the static and dynamic --until it reached compiling my own program, when in stopped with the following error: xxx.hs:1:1: Dynamic linking required, but this is a non-standard build (eg. prof). You need to build the program twice: once the normal way, and then in the desired way using -osuf to set the object file suffix. /usr/bin/ghc returned ExitFailure 1 I don't have profiling enabled (or is it an example of non-standard build?), but I also don't understand the proposed solution of building the program twice. Compiling with "ghc --make -dynamic {-X...}* Main.hs" ends with the same error.. (I also know there is a multi-step manual way to do it, so maybe it could pinpoint the problem -- but I haven't tried it yet) What could be the problem? -- Markus Läll
