Description:
------------
When compiling PHP 5.3.0 beta1 with both libidn and intl, I get this 
error message : 

ld: duplicate symbol _zif_idn_to_ascii in ext/intl/idn/idn.o and 
ext/idn/idn.o
collect2: ld returned 1 exit status

PHP 5.3.0.beta1 compile nicely when only one of them is enabled. 

Reproduce code:
---------------
./configure --enable-intl --with-idn
make


Expected result:
----------------
Compilation successful.

Actual result:
--------------
ld: duplicate symbol _zif_idn_to_ascii in ext/intl/idn/idn.o and 
ext/idn/idn.o
collect2: ld returned 1 exit status

One has nothing to do with the other. The first is certainly the pecl extension while the other is a new core function (via intl for 5.3, and as ICU is always present in 6.x, the function will always be enabled).

I already asked in #php-doc how to solve the problem in the documentation and so far I got no answer. We have to find a solution asap.

Read the report again Pierre. It has nothing todo with docs.
Its about getting useful errormessage from ./configure when trying to enable them both.

It is a documentation problem.

You can't have two function with the same name at the same in PHP. So the short version is:

do not compile pecl/idn with 5.3 statically, or even shared as the error will happen at runtime then.

patch for intl

I would rather add that to pecl/idn first.

Also how will ext/standard conflict with external ext? That's really a problem to be solved pecl/idn.

Did you actully read the patch Pierre ? ext/standard is ZEND_MOD_REQUIRED **NOT** ZEND_MOD_CONFLICTS ;-)

Doc issue, not a bug in 5.3 itself.

This bug has been fixed in the documentation's XML sources. Since the
online and downloadable versions of the documentation need some time
to get updated, we would like to ask you to be a bit patient.

Thank you for the report, and for helping us make our documentation better.
