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 2.61 is installed in the computer that generates our nightly
10 dnl snapshots, so we need to be compatible with that. (Also, some files
11 dnl in Autoconf 2.62 and 2.63 sources are not GPLv2 compatible.)

1398 # Bug 1081: If both TRE and libc define the regfree function,
1399 # ELinks needs to use the version defined by TRE because
1400 # that's the one compatible with regex_t initialized by the
1401 # regwcomp function of TRE. Therefore put $TRE_LIBS at the
1402 # very beginning of $LIBS so that the linker hopefully finds
1403 # regfree there before it examines libc. In particular,
1404 # $PERL_LIBS appears to often include "-lc".
1406 # This scheme still risks a crash if ELinks is linked with
1407 # some static library that uses GNU <regex.h> extensions that
1408 # TRE does not implement. For example, the library might call
1409 # re_compile_pattern, which is found in GNU libc, and then
1410 # regfree, which is found in TRE and probably crashes with the
1411 # GNU-initialized regex_t. Ways to avoid such crashes:
1413 # - Change TRE so it defines only tre_... functions and does
1414 # not attempt to override the POSIX names by default.
1416 # - Change ELinks to access TRE only via dlopen and dlsym.
1417 # The problem then is how to find the correct file name.
1418 # There might be libtre.so.4 and libtre.so.5 with different
1419 # ABI. How can this configure script detect which of them
1420 # matches the <tre/regex.h> in the include path?
1422 # - Replace the static library with a shared library. At
1423 # least on GNU/Linux, when the shared library is built, the
1424 # linker should note that e.g. regfree is defined in libc
1425 # and has the GLIBC_2.0 version there, and write that
1426 # version string to the shared library as well; because TRE
1427 # does not provide regfree with that version, any regfree
1428 # calls at run time should then get resolved to libc.

1452 # the executable to its dynamic symbol table. ELinks uses this for
1455 # 1. If ELinks detects a bug, it can try to display a backtrace by
1456 # calling backtrace_symbols_fd() in the GNU libc. The glibc-2.3.6
1457 # manual states users of GNU ld must pass -rdynamic to make the
1458 # symbols available to the program.

1462 # call ELinks functions. This can be implemented either by
1463 # registering all callable functions in ELinks-specific data
1464 # structures, or by letting the dynamic linker handle them.
1465 # The latter way requires something equivalent to -rdynamic.
1467 # Because backtraces are not needed for correct operation, and bug
1468 # 73 is not yet being fixed, the configure script and makefiles
