Hello,

In a project i added version.c as source for each target in this project.
But a problem raised when i made this construction:

obj wfd_iht.o : wfd.c : <define>IHT ;
exe iht
:
        wfd_iht.o
        httpserv.c
:
        <include>.
;

error: Duplicate name of actual target:
<p../../build/appl/wfd/gcc-4.5.3/debug>wfd_iht.o
error: previous virtual target { gcc%gcc.compile.c-wfd_iht.o.OBJ { wfd.c.C }
}
error: created from ./wfd_iht.o
error: another virtual target { gcc%gcc.compile.c-wfd_iht.o.OBJ {
../../build/version.c.C } }
error: created from ./wfd_iht.o
error: added properties:  none
error: removed properties:  none

I could made an object of version.o and include that as source, but I like
to know if it possible to exclude in this case version.c in the taget
wfd_iht.o ?

Regards,
