--- Comment #6 from Jacob Carlborg <d...@me.com> --- (In reply to Steven Schveighoffer from comment #5) > In fact, I actually TRY your suggestion to solve the original problem and it > doesn't work. See the PR: > https://github.com/dlang/phobos/pull/4744#issuecomment-241876407 No module info is generated if -lib is passed unless coverage, static constructor , destructor or unittest calls are used. This is regardless if classes are referenced or not. https://github.com/jacob-carlborg/dmd/blob/204b4b3b5a2ccbc697fb4e9ae422294ee21867d2/src/glue.c#L457 I think the simplest workaround is to not use -lib but archive the object files manually using "ar". --
