From what I understand in the error message, the linker cannot find a druntime function: void core.stdc.stdarg.va_end(void*). I would advise to check that the druntime lib is in the import path. In your the dmd repository, you should have a dmd.conf file containing something like: [Environment64] DFLAGS=-I% P%/../src/phobos -I% P%/../src/druntime/import -L-L% P%/../lib64 -L--export-dynamic (% P% means the compiler path). This should help you to fix your command line adding for instance: -I/usr/local/lib/dmd/druntime/ In my dmd installation (2.066.0), the druntime is contained in libphobos.a/libphobos.so. Are you linking with libphobos? On 08/31/2014 03:53 PM, seany wrote:I have several files, which I am trying to import as modules to a central file.

I have checked my ldc installation: the druntime library is located in ldc2-0.12.0-linux-x86/x86/libdruntime-ldc.a You should also add a some extra flags like: -L-L/path/to/ldc/lib/<architecture> -L-Ldruntime-ldc .

Have you tried something like this:
find /lib /usr/lib* /usr/local/lib* -name \*.a | grep -i druntime
or a simple:
locate druntime
?

In case you don't find any druntime library, try to see if the missing
symbol is in the libphobos2.a file (you'll first have to identify the
directory where phobos is located):
$ nm libphobos2.a | ddemangle | grep stdc | grep va_end
00000000 T nothrow void core.stdc.stdarg.va_end(char*)
If you get a similar result, your next step will be to try compiling
your program with phobos.

About find command :
I use find / -iname *druntime*.a with root permission - how else
will i find what is where, kfind probably uses find internally
too, or boost, egal ...
for the nm command :
without ddemangle, i dont have the command installed :
0000000000000000 T
_D4core4stdc6stdarg6va_endFNbPS4core4stdc6stdarg13__va_list_tagZv

U
_D4core4stdc6stdarg6va_endFNbPS4core4stdc6stdarg13__va_list_tagZv
now what?

I suggest to try linking with both phobos and tango. Only the druntime functions contained in phobos should be used by the linker (if I am correct). Otherwise, did you take a look at code.dlang.org? Depending on your needs, there might be a dub package you could use to fill in for the missing Tango functionalites.
