Raw Blame History

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

# Check for -rdynamic
#
# gcc -rdynamic calls ld -export-dynamic, which adds all symbols of
# the executable to its dynamic symbol table. ELinks uses this for
# two purposes:
#
# 1. If ELinks detects a bug, it can try to display a backtrace by
# calling backtrace_symbols_fd() in the GNU libc. The glibc-2.3.6
# manual states users of GNU ld must pass -rdynamic to make the
# symbols available to the program.
#
# 2. It would eventually be nice to dynamically load shared
# libraries as plugins (bug 73). The plugins must be able to
# call ELinks functions. This can be implemented either by
# registering all callable functions in ELinks-specific data
# structures, or by letting the dynamic linker handle them.
# The latter way requires something equivalent to -rdynamic.
#
# Because backtraces are not needed for correct operation, and bug
# 73 is not yet being fixed, the configure script and makefiles
# should not complain to the user if they find that -rdynamic does
# not work. Besides, it was reported at elinks-users on 2006-09-12
# that gcc-3.4.2 with "ld: Software Generation Utilities - Solaris
# Link Editors: 5.8-1.284" on Sun Solaris 8 Sparc does not support
# -rdynamic but does something equivalent automatically. (This was
# tested with "nm -D elinks | grep redraw_from_window".)
#
# FIXME: This check doesn't work. Something to do with the compiler
# happily ignoring it and stderr not being checked for error messages.

# warning: the address of `builtin_modules' will always evaluate as `true'
# This hits the object_lock and foreach_module macros in particular.
# It would be okay to put something in the macros to avoid the warning,
# but currently this seems to require defining parallel macros that skip
# the NULL check, and that's too ugly. So we instead disable the warning.
# GCC 4.2.1 needs -Wno-address, but GCC 4.2 snapshots need -Wno-always-true.
# GCC 4.1.3 recognizes neither and exits with code 1 if they are given.
