#47153 [Com]: Problem in config.m4
ID: 47153
Comment by: galtgendo at o2 dot pl
Reported By: mmarkus69 at hotmail dot com
Status: No Feedback
Bug Type: cURL related
Operating System: Ubuntu 8.04
PHP Version: 5.2.8
New Comment:
Perhaps (just a guess), reporter run autoreconf.
With a fairly recent autoconf, certain assumption of
this macro is incorrect:
AC_CHECK_HEADER (as opposed to AC_CHECK_HEADERS)
does NOT define HAVE_HEADER_H for the header it checks.

apt-get -y install libcurl4-gnutls-dev
Anyway, this is a logical error in interface.c that falls under the
heading:
/* {{{ cruft for thread safe SSL crypto locks */
Thus, you need to compile a thread-safe version (zts) of PHP to see the
warning. Here are the options that I used:
./configure \
--disable-cli \
--enable-embed=static \
--disable-cgi \
--disable-ipv6 \
--enable-maintainer-zts \
--disable-shared \
--enable-static \
--with-config-file-path=. \
--with-zlib \
--with-curl \
--without-pear \
--with-tsrm-pthreads
Let me know if you still have problems replicating this issue and
thanks for taking the time to look into it.
[2009-01-20 01:03:15] j...@php.net
So what did you do wrong? The same configure works fine for me on
several installation. Did you go and compile curl yourself? I bet you
have 2 (or more) installations there that conflict which each other..
[2009-01-19 20:45:32] mmarkus69 at hotmail dot com
Description:
When compiling using --with-curl, the following error appears:
php-5.2.8/ext/curl/interface.c:68:6: warning: #warning libcurl was
compiled with GnuTLS support, but configure could not find gcrypt.h;
thus no SSL crypto locking callbacks will be set, which may cause
random crashes on SSL requests
However, configure does report that it has found gcrypt.h when it
runs.
The problem seems to be in ext/curl/config.m4 since it never defines
HAVE_GCRYPT_H after checking for the aforementioned header file. This
then causes the warning in interface.c which does check that
HAVE_GCRYPT_H is defined.
A similar problem seems to occur with HAVE_OPENSSL_CRYPTO_H although I
have not investigated the situation in depth.
Proposed solution (in the form of a diff patch):
--- ext/curl/config.m4 2008-11-07 15:18:45.0 -0600
+++ config.m4 2009-01-19 13:59:57.0 -0600

#42374 [Asn]: --as-needed causes configure failures
ID: 42374 User updated by: galtgendo at o2 dot pl Reported By: galtgendo at o2 dot pl Status: Assigned Bug Type: Feature/Change Request Operating System: Gentoo PHP Version: 5.2CVS-2007-08-23 Assigned To: jani New Comment: OK, I did some more reading on autotools. A quote from autoconf info page: -- Variable: LDFLAGS ... This variable's contents should contain options like `-s' and `-L' that affect only the behavior of the linker. ... Don't use this variable to pass library names (`-l') to the linker; use `LIBS' instead. So title of this bug should be something along the lines of: 'rewrite your macros to conform to specs instead of simply work' While doing that it may be a good idea to split all those libraries into groups, so every extension (and php itself) doesn't get linked with every libs needed for other extentions. Previous Comments: [2007-11-06 12:26:45] galtgendo at o2 dot pl Please disregard most of my last comment, I misunderstood something. I thought that --as-needed prevents linking with unused libraries, but it only marks them as unused, so above listings of ldd -u mean that it actually works, not the opposite. Anyway, what was exactly the problem that --preserve-dup-defs works around, cause the note in configure.in says only that there was a problem with older libtool, not what was it ?

we? :)

a) it seems to be experimental
yes, but it usually work.
b) might cause problems in dynamic loading such as our shared
extensions, f.e. php - pdo - pdo driver (haven't tested yet :)
I have tested it with some extensions and seem to work fine, except
that the IMAP extension does not compile because configure checks fail
for the same reason the reporter is showing here.
d) PHP build system does not link with anything else than what is
actually needed anyway (AFAIK)

although in most cases the guilty stuff is foobar_config scripts or
pkgconfig scripts that inject uneeded dependencies (uneeded at least
on linux)

After some investigation to this flag I'm leaning towards simply
filtering it out totally if someone tries to use it. Reasons being:
a) it seems to be experimental
b) might cause problems in dynamic loading such as our shared
extensions, f.e. php - pdo - pdo driver (haven't tested yet :)
c) requires that pretty much everything in the system has to be
compiled using it
d) PHP build system does not link with anything else than what is
actually needed anyway (AFAIK)

For a simple test case:
#include glib.h
int main()
{
g_print(test done\n);
return 0;
}
gcc -o minitest -Wl,--as-needed `pkg-config glib-2.0 --cflags`
minitest.c `pkg-config glib-2.0 --libs`
- compiles fine
gcc -o minitest -Wl,--as-needed `pkg-config glib-2.0 --cflags`
`pkg-config glib-2.0 --libs` minitest.c
- gives
/tmp/ccKZrHDW.o: In function `main':

#42374 [Fbk-Opn]: --as-needed bug - follow-up

-Status: Feedback

Bug Type: Compile Failure

New Comment:
Well, that's incorrect.
PHP_CHECK_LIBRARY calls AC_CHECK_LIB.
without -Wl,--as-needed it does not matter whether libs are in LDFLAGS
or in LIBS, with that flag however all dependent libraries must appear
after the objects.
AC_CHECK_LIB does something like
i686-pc-linux-gnu-gcc -o conftest ${CFLAGS} ${LDFLAGS} conftest.c
${LIBS}
(more or less)
that check fails with --as-needed flag if lib is added to LDFLAGS
so it does not matter if it gets restored, cause the check already
failed - those are the false negatives I'm talking about.
All the other macros from the patch seem to do this, so that's why I
changed them. I'm not sure if something got broken, however it was
correct for the ext/ldap/config.m4 so there's at least a chance it will
work for the rest.
Previous Comments:

PHP_CHECK_LIBRARY restores the LDFLAGS after doing the test so it
shouldn't be any problem?
And bug #41973 was about ext/ldap and that was fixed.
I'd fix these case by case rather than blindly changing places unlikely
to even cause any problems.
[2007-08-22 15:40:41] galtgendo at o2 dot pl
Well, I'm not 100%, if I was, I would mentioned it, not asked for
futher testing.
And AFAIK that commit from bug #41973 was only
http://cvs.php.net/viewvc.cgi/php-src/ext/ldap/config.m4?r1=1.44r2=1.45diff_format=u
so only about ext/ldap/config.m4 (as in my patch).
What's more, although I can't recall if it made any difference you
should consider changes in acinclude.m4, cause in PHP_CHECK_LIBRARY
macro you were adding libraries to LDFLAGS instead of LIBS and that's
most common source of --as-needed bugs. That's why I'm talking about
false negatives - standard configure check would put those libraries in
wrong place and check would fail even if the library was OK.
[2007-08-22 14:46:27] [EMAIL PROTECTED]

places?

As I don't see a way to attach anything here, I'll give you a link to
an old gentoo bug with my patch. It's
http://bugs.gentoo.org/show_bug.cgi?id=151444
It's an old bug so it still covers the part from the closed bug.
BTW your bugzilla is REALLY annoying.
