Tanks Chris,

Sorry for the misunderstanding about the version.c file. The version.c file
should be compiled with each target, so also the target wfd. So in the
parend project definition i put this version.c as <source> in the
requirement section.

Now i think that the error from bjam is revering to the fact that version.c
is compiled for target " obj wfd_iht" and for " exe iht" with different
flags, but with the same name.

My solution is now to include the version.o instead of version.c, that seems
to work.

Two questions i still have:
- It seems that the <source>version.c is also included in "obj wfd_iht" but
creating a object from two source files (wfd.c and version.c)?
- Is it possible to exclude a particular source item that is specified in
the parent project file as mandatory ?
