[PD-dev] Error when crosscompiling pdlua

[Frank Barknecht]

Hallo,

some more info: Could this be related to Claude's findings mentioned
in the lua.c file:

/** Pd loader registration, defined in pd/src/s_loader.c but not exported. */
 void sys_register_loader(loader_t loader);

 /** Pd extern dir declaration (for help finding), defined in pd/src/m_class.c but not exported. */
  void class_set_extern_dir(t_symbol *s);

If sys_register_loader is "not exported", how are loaders meant to be
built? And why does gcc not complain on native Linux using practically
the same command line?

Ciao
