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

260 dnl Link Editors: 5.8-1.284" on Sun Solaris 8 Sparc does not support

262 dnl tested with "nm -D elinks | grep redraw_from_window".)
