I'm trying to port an open source existing ocaml app from Makefiles to dune. The application includes some C and C++ stubs. I tried to add a test.c file in a library like this:

(library
    (name cdk)
    (public_name [...])
    (wrapped false) 
    (modules
[...]
    )
    (libraries IO unix str threads camlp-streams autoconf)
    (flags (:standard -w -32 -w -50 -w -27 -w -35 -w -69))
    (foreign_stubs
        (language c)
        (names test)
        (include_dirs ../../../)
    )
)

the C file is just an include of stdio.h. I then get this error:

Error: Dependency cycle between:            
   _build/default/src/utils/cdk/test.o
-> _build/default/src/utils/cdk/libcdk_stubs.a
-> _build/default/src/utils/cdk/cdk.cmxs
-> _build/default/src/utils/cdk/test.o
-> required by alias src/utils/cdk/all
-> required by alias default

This happens whatever C file I include. What is this cycle being created? How can I fix this? Thank you!
