Adjust some more code that was depending on the function and delegate calling conventions being equal. There's also an instance in `tango.text.convert.Layout` that should be adjusted: {{{ Index: tango/text/convert/Layout.d =================================================================== --- tango/text/convert/Layout.d (revision 4578) +++ tango/text/convert/Layout.d (working copy) -660,8 +660,12 @@ case TypeCode.STRUCT: auto s = cast(TypeInfo_Struct) type; - if (s.xtoString) - return Utf.fromString8 (s.xtoString(p), result); + if (s.xtoString) { + char[] delegate() toString; + toString.ptr = p; + toString.funcptr = cast(char[] function()) s.xtoString; + return Utf.fromString8 (toString(), result); + } goto default; case TypeCode.INTERFACE: }}}

This should help get the runtime built.
FOR D1:
=======
1) Do a checkout of tango trunk into the ldc root dir (along dmd, gen, runtime etc).

    *   $ ls
    *   dmd dmd2 gen ir ...
    *   $ svn co http://svn.dsource.org/projects/tango/trunk tango

2) Compile the runtime

    *   sh build.sh

FOR D2:
=======
Highly experimental!!!

1) Do a checkout of druntime trunk into the ldc root dir (along dmd, gen, runtime etc).

    *   $ ls
    *   dmd dmd2 gen ir ...
    *   $ svn co http://svn.dsource.org/projects/druntime/trunk druntime

2) Patch druntime

    *   cd runtime
    *   sh patch-druntime.sh

3) Compile druntime

    *   cd ../druntime/src
    *   sh build-ldc.sh

=======
Enjoy!
