I just created a shared library in D using DMD in Ubuntu and run into the following error when trying to use it

  undefined symbol: _deh_beg

I found this old thread where it is suggested to create a dummy main method : http://lists.puremagic.com/pipermail/digitalmars-d/2007-October/026970.html

I did that and it fixed the error, but it doesn't seem quite right.

My DMD call looks like this

  dmd -shared -fPIC <DFILES HERE> -I../src -ofbeep.so

The compiler is able to generater position independant code but as far as I remember, there are still some issues in druntime which make it difficult to create dynamic librarys in D. You need to somehow initialize the runtime.

As far as I know the runtime is not ready for shared libraries yet.

I will try something like this
