This is due to upstream glpk decision to export only API
function, see my discussion about it:
http://lists.gnu.org/archive/html/help-glpk/2009-03/msg00041.html
from glpk src/Makefile.am
we have:
libglpk_la_LDFLAGS = -version-info 22:0:22 \
-export-symbols-regex '^(glp_|_glp_lpx_).*'
These are the two functions called by octave
(if I am not wrong) and both are marked obsolete in glpk
__glp_lib_fault_hook
__glp_lib_print_hook
but in the API there is only
_glp_term_hook (exported)
so probably we need to re-write the interface...
in any case from glplibo4.c and glplibo3.c
__glp_lib_print_hook is a call to _glp_term_hook
__glp_lib_fault_hook is just an assert check.
************************************************************
void lib_print_hook(int (*func)(void *info, char *buf), void *info)
{ /* (obsolete) */
#if 0 /* iso c complains */
int (*hook)(void *, const char *) = (void *)func;
#else
int (*hook)(void *, const char *) = (int(*)(void *, const char *))
(func);
#endif
lib_term_hook(hook, info);
return;
}
***************************************************************
void lib_fault_hook(int (*func)(void *info, char *buf), void *info)
{ /* (obsolete) */
xassert(func == func);
xassert(info == info);
return;
}
