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

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