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