If I link my DMD 2.066.1/ GtkD (latest version) app with static Phobos2 I get

Linking executable: ../bin/Debug/compo
../objdir/mainwin.o: In function `_D4core7runtime7Runtime17__T11loadLibraryZ11loadLibraryFxAaZPv':
/usr/include/dmd/druntime/import/core/runtime.d:233: undefined reference to `rt_loadLibrary'
collect2: ld returned 1 exit status

If I change the link spec to use libphobos2.so, then the app links, and runs, but it crashes the first time I try to read something from a file with stream.File.readString.

Does this ring a bell with anyone.

It looks like you are missing a required library. Are you linking with ld? If so, make sure you run dmd with -v to see the link line it uses.

Telling the linker to use the dynamic linking so - on Ubuntu, that appears to be /lib/i386-linux-gnu/ld-linux.so.2 - makes no difference.

Does your code call Runtime.loadLibrary anywhere?

It looks like rt_loadLibrary is only implemented when on Windows or with version(Shared).
