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 ?

Meindert,

 

It is not clear to me what version.c file your are referring to since I do not see it in your example.  You may want to try this instead to fix it:

 

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

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 ?

Meindert
