           Summary: Add DMD compiler switch to prevent automatic linking to
                    phobos.lib/libphobos.a
           Product: D
           Version: 1.006
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: enhancement
          Priority: P1
         Component: DMD
        AssignedTo: bugzilla@digitalmars.com
        ReportedBy: thecybershadow@gmail.com


Currently, the compiler (dmd.exe) forces to link against the standard library with a fixed name. This greatly stagnates the use of alternating standard libraries, like Tango, which have to resort to replacing the standard "phobos.lib" (or "libphobos.a") file - which makes it difficult to work with both Phobos and Tango projects at the same time.

Personally, I consider adding a switch which allows to specify an alternate standard library to link to of very high importance. The current set-up prevents complex build systems, like DSSS, to allow specification of a project's used standard library - and thus facilitate building software and dependencies independently of the currently-configured library. (Currently, your D compiler can either be in Phobos mode or Tango mode, and you have to manually switch between them) - that is, without using OptLink directly, which is very problematic in itself (the interface between DMD and OptLink is ill-defined - library deps change, etc, etc.).

For what it's worth, I do think it makes sense for the compiler to implicitly link a library expected to contain its runtime code.  In fact, Tango was even designed to support this configuration.  It isn't the default simply because it adds complexity but only benefits a small portion of the community.  The need for users to switch between configurations is a valid concern however, so I can't say I disagree with this request.  If nothing else, it would occasionally be useful to link a debug vs. a release version of the compiler runtime without replacing the library file itself.

From the spec, it's fixed in 1.021
