I have several files, which I am trying to import as modules to a central file.

However, whyile trying to complie with
dmd -L-ltango-dmd <list of files space separated>

However, I am getting this error :

I tried a small hellow owrld file, the same problem.

Yes, the 64 bit linux system updated today, and since then, this is a problem - how do I start to look for cause and solve?

Oh, I am using netrunner linux with arch/manjaro core.

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?

This is what I have :
Environment]
DFLAGS=-I/usr/include/dlang/dmd -L-L/usr/lib -L-L/usr/lib32 -L--export-dynamic

I am linking against tango

ldc -I/path/to/tango -L-L/path/to/tango  -L-ltango-dmd \

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 .

there is no /path/to/ldc/lib in my system - i have an /etc/ldc.conf
and a /usr/bin/ldc2

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
                 U _D4core4stdc6stdarg6va_endFNbPS4core4stdc6stdarg13__va_list_tagZv

now what?
