It's not annoying at all, we use it in strategic places. For example, see how pypy/rlib/_rffi_stacklet.py implements a stacklet C library that can be used in RPython. It uses an "ExternalCompilationInfo" (eci) object: - separate_module_files lists the .c files you want to compile and link - separate_module_sources is an easy way to embed C snippets (each source will create a .c file) Then you can use rffi.llexternal with "compilation_info=eci" to declare a function defined in this library. -- Amaury Forgeot d'Arc
