235 dnl gcc -rdynamic calls ld -export-dynamic, which adds all symbols of
236 dnl the executable to its dynamic symbol table. ELinks uses this for
239 dnl 1. If ELinks detects a bug, it can try to display a backtrace by
240 dnl calling backtrace_symbols_fd() in the GNU libc. The glibc-2.3.6
241 dnl manual states users of GNU ld must pass -rdynamic to make the
242 dnl symbols available to the program.
244 dnl 2. It would eventually be nice to dynamically load shared
245 dnl libraries as plugins (bug 73). The plugins must be able to
246 dnl call ELinks functions. This can be implemented either by
247 dnl registering all callable functions in ELinks-specific data
248 dnl structures, or by letting the dynamic linker handle them.
249 dnl The latter way requires something equivalent to -rdynamic.
251 dnl Because backtraces are not needed for correct operation, and bug
252 dnl 73 is not yet being fixed, the configure script and makefiles
253 dnl should not complain to the user if they find that -rdynamic does
254 dnl not work. Besides, it was reported at elinks-users on 2006-09-12
255 dnl that gcc-3.4.2 with "ld: Software Generation Utilities - Solaris
256 dnl Link Editors: 5.8-1.284" on Sun Solaris 8 Sparc does not support
