Description

I get this linker error:

`.gnu.linkonce.t_D5tango4text7convert6Layout13__T6LayoutTaZ6Layout9fromUtf32FAwAaZAa' referenced in section `.gnu.linkonce.d._D5tango2io5Print12__T5PrintTaZ5Print7__ClassZ' of /home/dateruser/Dater/dsss/lib//libSDD-tango-io.a(tango.io.Stdout.o): defined in discarded section `.gnu.linkonce.t_D5tango4text7convert6Layout13__T6LayoutTaZ6Layout9fromUtf32FAwAaZAa' of /home/dateruser/Dater/dsss/lib//libSDD-tango-io.a(tango.io.Stdout.o)

For me it works, if I add this alias into tango.text.convert.Layout:

alias Layout!(char) dummyAlias;

So it seems to prevent the section from being disregarded.

D2 or D1 ?

I'd guess this a part of that compiler bug series, regarding sections?

D1 with svn trunk.

There was not more information about sections.

there was another one with the same problem in the german irc.

He used minid and the wchar/dchar versions of this alias removed his linker errors on windows

Does this ticket have a relevant bugzilla entry?

11/23/07 20:59:01 changed by larsivi

I suppose it is bugzilla 1508.

FWIW, the unittest.sh script expose the same error, this time fixed by alias StreamIterator!(char) dummyAlias;

Any thoughts on what to do with these workarounds? We could put them in a DMD and linux version block, but it will be fragile. Other apps will quickly require other aliases again.

#769 is a duplicate of this.

11/28/07 13:25:36 changed by larsivi

This is fixed in DMD 1.024 / 2.008
