Description:
------------
on my machine (CentOS) the libpcre.a is in /usr/lib64/ and the pcre.h is in 
/usr/include

If I try --with-pcre-regex=/usr then it can't find the library.


Test script:
---------------
./compile --with-pcre-regex=/usr

Expected result:
----------------
It compiles.

Actual result:
--------------
checking for PCRE library location... configure: error: Could not find libpcre.
(a|so) in /usr

Does --with-libdir=lib64 allow configure to work?

[2013-06-06 15:14 UTC] kovtun at complex dot lviv dot ua

No, it doesn't help

./configure --prefix=/usr/local/php54  --with-pcre-regex=/usr   --with-libdir=lib64
.........

php-5.4.15 version

[2013-06-06 17:42 UTC] ab@php.net

ln -s /usr/lib/x86_64-linux-gnu/libpcre.a /usr/lib/libpcre.a

But why would you want to use 8.12 when bundled is 8.32?

[2013-06-06 17:43 UTC] ab@php.net

Also i wouldn't say this is a bug, looking into non standard dirs is ignored by 
many projects.

because 8.12 is current version in ubuntu-11.10


> ln -s /usr/lib/x86_64-linux-gnu/libpcre.a /usr/lib/libpcre.a

Thank You. It works.

>Also i wouldn't say this is a bug, looking into non standard dirs is ignored by many projects.

sorry, I just don't have much experience and I don't know that /usr/lib/x86-64-linux-gnu/ is non-standard directory..

Here's the standard *nix directory structure 
http://en.wikipedia.org/wiki/Unix_directory_structure

Since you compile it yourself, you still could benefit from a better PCRE in PHP. 
That wouldn't affect anything on your system.

This is a problem with the pcre supplied with w.g. Ubuntu 15.04, and similariy in SuSE 13 or Redhat Enterprise Linux 7. While the former has /usr/lib/x86_64-linux-gnu/libpcre.so, the latter both have it in /usr/lib64.
