Hi All (again),


I got the following error message when my program is going to be linked:

------------------------ error -------------------------------
default/common/configuration/Configuration_1.o:(.data+0x98): undefined 
reference to `_D5tango4text3xml9SaxParser12_ModuleInfoZ'
------------------------ error -------------------------------

Configuration_1.o is the output file of my source.
I compiled my program on two Linux machines. It works on one machine, 
but not the other.

I suppose:
1. the tango libraries are different. (I will verify it tomorrow in my 
office)
2. the SaxParser contains some template implementation. how this part is 
compiled? can this be a reason of my problem?

BTW: What is ModuleInfoZ?? I have not found it in SaxParser.d at all.

ModuleInfo is the instance of the ModuleInfo class that the compiler 
generates for a d source file.  Every compiled file has one.

this shows all ModuleInfo instances in tango:
nm libtango*.a | grep ModuleInfo

It appears that the SaxParser module is not defined in the library.  I would 
guess that your tango lib is not compiled from the .d files you are using 
for imports, one of those two is out of date.

Thanks. The build system links with another SaxParser
