In 'guile-config link', the flag '-lgc' is missing; it is needed when linking smobs. The function SCM_NEWSMOB calls GC_register_finalizer_no_order() in header gc.hIt shouldn’t be needed when libguile is a shared library, at least not on ELF platforms where the shared library contains ‘NEEDED’ headers. It is needed when libguile is static, but in that case you should use ‘pkg-config guile-2.0 --libs --static’ (‘guile-config’ is deprecated.)
The file gc.h says that it is only for Java implementations. But as noted above, it is called by SCM_NEWSMOB, so until it is taken away, - lgc must be used, otherwise the linker will require it. My platform is otherwise Mac OS X; objective code format is Mach-O.
