How can I generate a relocatable module from object files (ld --relocatable) instead of an archive library?
Or, is it possible to create an alias that containd the list of objects corresponding to the sources in a [ glob *.cpp ]?

My application uses modules created in subdirectories and need to have the object files in the command line instead of an archive library.

This is what I would like to do:

lib MyModule : [ glob *.cpp ] : <link>module ; 
exe MyApp : App.cpp : <library>MyModule ;

thoat would result in:
cc -c a.cpp
cc -c b.cpp
ld -r MyModule.o a.o b.o
cc -c App.cpp
cc -o MyApp App.o MyModule.o

or
cc -c a.cpp
cc -c b.cpp
cc -c App.cpp
cc -o MyApp App.o a.o b.o

Thanks.
