Hi Alex,
as suggested in bugzilla I try to add an extra [] at the end of the
AC_RUN_IFELSE and the configure goes ahead (I report the very simple
patch into bugzilla).
Unfortunately I have a similar issue with the SSL certificate check that
comes from acinclude/lib-checks.m4 (around line 108 and 128). In this
case I add double [[ after AC_LANG_PROGRAM and remove [ from
AC_MSG_RESULT, because the same syntax that I see in configure.ac
(forgive me, but I am not an autotools expert).
By the way this modifications have overcome the error on SSL, but I
found a similar issue in the krb5 checks from the acinclude/krb5.m4 .
I report the same syntax scheme as above and after that the configure
goes well...
So now is the compile steps that fails, I have the following error:
../../src/ssl/gadgets.h:223:7: error: 'Ssl::CertificateProperties'

'Ssl::CertificateProperties::mimicCert' [-Werror=attributes]

I suppose that this issue came from my SSL modification in configure (I
am using openssl 1.0.1e)...
Have you any idea on how to fix it?
Thank you for the support,
Stefano.

Thank you Amos for your answer!
I am using these cross compiler flags (that seems right for me):
--build=x86_64-linux
--host=i586-oe-linux
--target=i586-oe-linux
Configure exit with this error:
checking for GNU atomic operations support... configure: error: in
`/<real_long_path>/tmp-eglibc/work/x86-oe-linux/squid/3.3.11-r19.9/squid-3.3.11':

Please see bug 3975. It has a generally wrong patch that may work OK for
your case and a discussion leading to the right solution (but no patch):
http://bugs.squid-cache.org/show_bug.cgi?id=3975
If you can implement that right solution, test, and post a patch that
would be great!
Cheers,
Alex.
Here are some details of my build machine:
It was created by Squid Web Proxy configure 3.3.11, which was
generated by GNU Autoconf 2.69.
automake (GNU automake) 1.12.6
uname -m = x86_64
uname -r = 2.6.32-5-xen-amd64
uname -s = Linux
uname -v = #1 SMP Fri May 10 11:48:05 UTC 2013
What can be the issue?
Cheers,
Stefano.

Hi list,
I am trying to compile squid 3.3.11 in our openembedded
environment,
but the configure step fails due to a cross compile check.
In version 3.1.23 there wasn't those checks and the build goes well...
So my questions are:
1) why from version 3.2 these checks are included in configure?
The change in behaviour is from newer autoconf being used to generate
the code tarballs. One of the reasons for that was to get better/easier
cross-compiling support.
2) are there any way to cross compile 3.3 (or 3.4)?
You should only** have to specify the ./configure options to tell it
which OS the compile is happening on (--build=X) and which OS type will
run the binary (--host=Y).
What exactly is the failure you are encountering?
** besides having the appropriate *-dev library versions installed for
cross-compiling against and tools that can cross-compile.
3) I read in the FAQ that from version 3.2 C++11 compilers is required,
I am using gcc 4.7.2, is it a supported compiler?
Not required. "Preferred" is the word for it. We have code to make use
of some C++11 only when available. Mostly we are taking advantage of the
increased compiler code checking in our build farm to remove bugs before
anyone notices them:-)
The switch to mandatory C++11 support for general builds is still being
discussed on squid-dev and IRC as to when the timing would offer least
pain for everyonea and how long we can procrastinate on it. It might
happen around Squid-3.6.
Any GCC 4.0+ (excluding 4.5 with broken stdlib definitions of
auto_ptr/unique_ptr) should work fine for Squid-3.2 and later. The later
versions are better though with more general C++11 support benfits than
the older ones.
Cheers
Amos
