1 dnl Process this file with autoconf to produce a configure script.
3 dnl There are two types of comments in this file.
4 dnl Comments that refer to Autoconf macros begin with "dnl", and m4
5 dnl discards them. Other comments begin with "#", and they get copied
6 dnl to the configure script, hopefully making it easier to read.
8 dnl Autoconf 2.13 generates an incomplete config.h.in; see ELinks bug 936.
9 dnl Autoconf 2.59 is installed in the computer that generates our nightly
10 dnl snapshots, so we need to be compatible with that.

1346 # Check for -rdynamic
1348 # gcc -rdynamic calls ld -export-dynamic, which adds all symbols of
1349 # the executable to its dynamic symbol table. ELinks uses this for
1352 # 1. If ELinks detects a bug, it can try to display a backtrace by
1353 # calling backtrace_symbols_fd() in the GNU libc. The glibc-2.3.6
1354 # manual states users of GNU ld must pass -rdynamic to make the
1355 # symbols available to the program.
1357 # 2. It would eventually be nice to dynamically load shared
1358 # libraries as plugins (bug 73). The plugins must be able to
1359 # call ELinks functions. This can be implemented either by
1360 # registering all callable functions in ELinks-specific data
1361 # structures, or by letting the dynamic linker handle them.
1362 # The latter way requires something equivalent to -rdynamic.
1364 # Because backtraces are not needed for correct operation, and bug
1365 # 73 is not yet being fixed, the configure script and makefiles
1366 # should not complain to the user if they find that -rdynamic does
1367 # not work. Besides, it was reported at elinks-users on 2006-09-12
1368 # that gcc-3.4.2 with "ld: Software Generation Utilities - Solaris
1369 # Link Editors: 5.8-1.284" on Sun Solaris 8 Sparc does not support
1370 # -rdynamic but does something equivalent automatically. (This was
1371 # tested with "nm -D elinks | grep redraw_from_window".)
1373 # With Sun Studio 11 on Solaris 9, we get "cc: Warning: illegal option
1374 # -dynamic"; then, cc proceeds anyway, but the option can prevent the
1375 # linker from finding the libraries listed in -l operands. So this
