232 dnl gcc -rdynamic calls ld -export-dynamic, which adds all symbols of
233 dnl the executable to its dynamic symbol table. ELinks uses this for
236 dnl 1. If ELinks detects a bug, it can try to display a backtrace by
237 dnl calling backtrace_symbols_fd() in the GNU libc. The glibc-2.3.6
238 dnl manual states users of GNU ld must pass -rdynamic to make the
239 dnl symbols available to the program.
241 dnl 2. It would eventually be nice to dynamically load shared
242 dnl libraries as plugins (bug 73). The plugins must be able to
243 dnl call ELinks functions. This can be implemented either by
244 dnl registering all callable functions in ELinks-specific data
245 dnl structures, or by letting the dynamic linker handle them.
246 dnl The latter way requires something equivalent to -rdynamic.
248 dnl Because backtraces are not needed for correct operation, and bug
249 dnl 73 is not yet being fixed, the configure script and makefiles
250 dnl should not complain to the user if they find that -rdynamic does
251 dnl not work. Besides, it was reported at elinks-users on 2006-09-12
