           Summary: Missing redundant symbols make compile time monsters
           Product: D
           Version: 1.025
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: critical
          Priority: P2
         Component: DMD
        AssignedTo: bugzilla@digitalmars.com
        ReportedBy: benoit@tionex.de


As Gregor explained in this posting

http://www.digitalmars.com/webnews/newsgroups.php?art_group=digitalmars.D&article_id=57473

build tools are forced to call DMD separately on each file. This turns out to be so bad. Project like DWT will take >15 min for a full compile. This is simply not acceptable.

I understand the problem, but it is not easy to fix. Also, it only is an issue for library builds, not application builds.

(In reply to comment #1)

Library builds are the basis for application builds. So your arguments for low priority is an argument for high priority to me.

I don't believe this is an issue any more. To create libraries from multiple files, just list all the files on one command line, and specify -lib. dmd will produce fine grained object files, sometimes many per source file.

This is the way Phobos is currently built, for example.
