I am a little confused by your description. You are trying to create a shared library on AIX that depends on another shared library? Adding the dependent shared library on the link line creating the new shared library should work. What do you mean by "it would link statically"? Adding the library to the link line will not include the code from the old library in the new one. Are you sure that the libraries you created are shared objects? AIX shared objects normally have file extension ".a", not ".so", and normally are an *ARCHIVE* of shared objects, not a bare shared object, but AIX will deal with either. AIX ignores shared libraries with ".so" extension unless the AIX linker -G (to create) / -brtl (to use) options are used. If you are forcing the AIX linker to use the files with the incorrect file extensions, the linker may be using different files than you expect or you may be invoking different linker semantics than you intend.
