db_create, db_env_create, db_strerror, db_sequence_create all 
defined in the project as extern(C) functions; and all it defined 
as C-functions in external libdb.a library.

The code works under Ubuntu, Linux Mint, Debian, Fedora, but not 
OpenSuse.

What particulars of building under OpenSuSE?

 db_create, db_env_create, db_strerror, db_sequence_create all
 defined in the project as extern(C) functions; and all it defined
 as C-functions in external libdb.a library.

 The code works under Ubuntu, Linux Mint, Debian, Fedora, but not
 OpenSuse.

My first thought would be that maybe the C library in question isn't
actually installed or that you need the dev version of the package
installed, and it isn't. If it can't find the symbols, maybe they just
aren't currently there. Alternatively, maybe it's not on your library load
path - though I would have expected something like that to be installed in
/usr/lib, which would definitely be in your library load path.

BTW, questions like this are better suited to the D.Learn newsgroup/forum.
