The first option specifies the directory of xulrunner includes, eg.
--with-xulrunner_includes=/usr/include/xulrunner
The second: compiler options to find library, eg.
--with-xulrunner_libs="-Wl,-R/usr/lib/xulrunner -L/usr/lib/xulrunner -lmozjs"
One can add eg.
CPPFLAGS="-I/usr/include/xulrunner" LDFLAGS="-L/usr/lib/xulrunner -Wl,-R/usr/lib/xulrunner"
to the ./configure
Before xulrunner wasn't found. Now it is possible.
Implement new heartbeat code to catch runaway execution of document
ECMAScript code. The old code uses JS_SetBranchCallback which is
deprecated in new versions of SpiderMonkey. The new code uses setitimer(2)
and the JS_SetOperationCallback and JS_TriggerOperationCallback interfaces,
introduced in SpiderMonkey 1.8.1. Compatibility with both the old
JS_SetBranchCallback and the new interfaces is maintained.
Avoid compilation error with GNUTLS 1.2.9:
/home/Kalle/src/elinks-0.12/src/network/ssl/ssl.c:258: error: implicit declaration of function ‘gnutls_priority_set_direct’
If the function is not available, use gnutls_set_default_priority instead.
Perhaps it'll work with bugzilla.novell.com, perhaps not.
In 0.13.GIT, the configure script sets disable_gnutls=yes if it
decides to use nss_compat_ossl. In recent elinks-0.12, the script
logs "explicitly disabled" if $disable_gnutls is set. Thus, merging
those together could have caused an incorrect claim to be logged.
Rearrange the logic to make it easier to extend to multiple libraries.
Code that deals with one library no longer needs to worry about each
alternative library separately. Instead just test and set the one
shared chosen_ssl_library variable.
While at it, get rid of openssl_withval, which merely mirrored the
with_openssl variable provided by Autoconf.
The configure script used to run libgnutls-config in order to find the
compiler and linker options needed for using GNUTLS, but GNUTLS 2.7
apparently doesn't ship that script any more. Use pkg-config instead.
GNUTLS 1.2.0 is the oldest version supported by ELinks, and that already
installs the gnutls.pc file required by pkg-config.
This commit also removes support for configure --with-gnutls=DIR.
The configure script used to look for libgnutls-config in DIR.
DIR thus had to be a directory where executable programs were installed,
and it's unlikely that gnutls.pc would be found there. So, any callers
that used this feature would have to be changed anyway, and they can as
well be changed to set the PKG_CONFIG_PATH environment variable instead.
Fix this error:
configure.in:1430: error: AC_SUBST: `[CONFIG_TRE]' is not a valid shell variable name
acinclude.m4:31: EL_LOG_CONFIG is expanded from...
configure.in:1430: the top level

This check used to be in src/elinks.h. Move it to configure.in so
that (1) the result can be logged and (2) ELinks won't even link with
TRE if wchar_t prevents its use.
Also, rename HAVE_TRE_REGEX_H to CONFIG_TRE, to reflect that it is not
always defined if the header exists.
The previous version could display its progress like this:
checking for TRE... checking for TRE in pkg-config... yes
checking for TRE header and library... yes
no
Omit the outer "checking for TRE..." and "no" (which was untrue
anyway), unless --without-tre causes the inner checks to be skipped.
elinks-lite in Debian does not depend on any libraries (except
gnutls). Including this option will allow elinks-lite to be built
without libtre dependency.
Conflicts:
src/session/session.c: Kept the elinks-0.13 version.
Bug 1077 did not occur in elinks-0.13 because
setup_session here calls render_document_frames

The AsciiDoc 7.1.2 configuration files included in the ELinks
source tree apparently aren't compatible with AsciiDoc 8.4.4:
[ASCIIDOC] doc/elinks.1.xml
FAILED: [listdef-bulleted] missing section: [listtags-None]
make[1]: *** [elinks.1.xml] Error 1
Fix this by including asciidoc.py from AsciiDoc 7.1.2 as well.
The build system now doesn't care at all whether the user has
installed some version of AsciiDoc or not.
C99 6.7.4p3 and 6.7.4p6 set some constraints on what can be done in
inline functions and how they can be declared. In particular, any
function declared inline must also be defined in the same translation
unit. To comply with that, remove inline specifiers from function
declarations in header files when the functions are not also defined
in those header files.
Sun Studio 11 on Solaris 9 is stricter than C99 and does not allow
references to static identifiers in extern inline functions. Make the
configure script detect this and define NONSTATIC_INLINE accordingly
in config.h. Then use that in the definitions of all non-static
inline functions.
Document the restrictions and this scheme in doc/hacking.txt.
Debian libmozjs-dev 1.9.0.4-2 has JS_ReportAllocationOverflow but
js-1.7.0 reportedly hasn't. Check at configure time whether that
function is available. If not, use JS_ReportOutOfMemory instead.

I didn't read the code of the tre library, but I suppose that when sizes of
wchar_t and unicode_val_T are equal it will work fine.
[ From bug 1060 attachment 508. --KON ]
When the user tells ELinks to search for a regexp, ELinks 0.11.0
passes the regexp to regcomp() and the formatted document to
regexec(), both in the terminal charset. This works OK for unibyte
ASCII-compatible charsets because the regexp metacharacters are all in
the ASCII range. And ELinks 0.11.0 doesn't support multibyte or
ASCII-incompatible (e.g. EBCDIC) charsets in terminals, so it is no
big deal if regexp searches fail in such locales.
ELinks 0.12pre1 attempts to support UTF-8 as the terminal charset if
CONFIG_UTF8 is defined. Then, struct search contains unicode_val_T c
rather than unsigned char c, and get_srch() and add_srch_chr()
together save UTF-32 values there if the terminal charset is UTF-8.
In plain-text searches, is_in_range_plain() compares those values
directly if the search is case sensitive, or folds them to lower case
if the search is case insensitive: with towlower() if the terminal
charset is UTF-8, or with tolower() otherwise. In regexp searches
however, get_search_region_from_search_nodes() still truncates all
values to 8 bits in order to generate the string that
search_for_pattern() then passes to regexec(). In UTF-8 locales,
regexec() expects this string to be in UTF-8 and can't make sense of
the truncated characters. There is also a possible conflict in
regcomp() if the locale is UTF-8 but the terminal charset is not, or
vice versa.
Rejected ways of fixing the charset mismatches:
* When the terminal charset is UTF-8, recode the formatted document
from UTF-32 to UTF-8 for regexp searching. This would work if the
terminal and the locale both use UTF-8, or if both use unibyte
ASCII-compatible charsets, but not if only one of them uses UTF-8.
* Convert both the regexp and the formatted document to the charset of
the locale, as that is what regcomp() and regexec() expect. ELinks
would have to somehow keep track of which bytes in the converted
string correspond to which characters in the document; not entirely
trivial because convert_string() can replace a single unconvertible
character with a string of ASCII characters. If ELinks were
eventually changed to use iconv() for unrecognized charsets, such
tracking would become even harder.
* Temporarily switch to a locale that uses the charset of the
terminal. Unfortunately, it seems there is no portable way to
construct a name for such a locale. It is also possible that no
suitable locale is available; especially on Windows, whose C library
defines MB_LEN_MAX as 2 and thus cannot support UTF-8 locales.
Instead, this commit makes ELinks do the regexp matching with regwcomp
and regwexec from the TRE library. This way, ELinks can losslessly
recode both the pattern and the document to Unicode and rely on the
regexp code in TRE decoding them properly, regardless of locale.
There are some possible problems though:
1. ELinks stores strings as UTF-32 in arrays of unicode_val_T, but TRE
uses wchar_t instead. If wchar_t is UTF-16, as it is on Microsoft
Windows, then TRE will misdecode the strings. It wouldn't be too
hard to make ELinks convert to UTF-16 in this case, but (a) TRE
doesn't currently support UTF-16 either, and it seems possible that
wchar_t-independent UTF-32 interfaces will be added to TRE; and (b)
there seems to be little interest on using ELinks on Windows anyway.
2. The Citrus Project apparently wanted BSD to use a locale-dependent
wchar_t: e.g. UTF-32 in some locales and an ISO 2022 derivative in
others. Regexp searches in ELinks now do not support the latter.

Commit message by me. --KON ]
With Sun Studio 11 on Solaris 9, we get "cc: Warning: illegal option
-dynamic"; then, cc proceeds anyway, but the option can prevent the
linker from finding the libraries listed in -l operands. To detect
this, move the -rdynamic check in configure.in down to a place where
the libraries have already been added to $LDFLAGS. So if -rdynamic
interferes with the search for libraries, ELinks won't use it.
Merely moving the test would also change the location of -rdynamic in
$LDFLAGS. Counteract that by making the test add -rdynamic to the
beginning of $LDFLAGS, rather than to the end. This may make the test
more reliable on Solaris.
ELinks used to call the MD5 code in libgnutls-openssl, part of
GNUTLS-EXTRA, which was licensed under GNU GPL version 2 or later.
In GnuTLS 2.2.0 however, the license of GNUTLS-EXTRA has been changed
to GNU GPL version 3 or later. This is no longer compatible with
GNU GPL version 2 as used in the current ELinks, because GPLv2 clause
2. b) requires the whole work to be licensed under GPLv2, and GPLv3
does not allow that.
If anyone is still using a pre-2.2 GnuTLS, he or she can tweak
configure.in to check the version or just assume it's old enough.
There is not much reason to do so though, as including the MD5 code
in ELinks seems to cost only about 4 kilobytes on i686.
(cherry picked from commit 9ca0182ec6)
On Mac OS X 10.5.4, <net/if.h> does not #include <sys/socket.h> but
uses struct sockaddr defined there. Autoconf 2.61 generates a
configure script that warns if the header can be preprocessed but not
compiled. The Autoconf manual cautions that future versions of
Autoconf will treat the file as missing in this case. To let ELinks
detect <net/if.h> even with a future Autoconf, make the test program
#include <sys/socket.h> before <net/if.h>.
