## #14651 — Hans Zaunere — 2005-02-06T00:03:52+00:00

Some time ago we talked about compiling PHP on an AMD64.  Joe Orton was kind enough to patch the 5.1 branch to include the --with-libdir directive to ./configure to allow for searching in libs in such places as /lib64 and /usr/lib64 and it worked great.

However, after downloading the php5-200502052330.tar.gz snapshot, things seem broken again.  My ./configure starts out like this:

./configure --with-libdir=lib64 --prefix=/usr/local/php --with-apxs=/usr/local/apache/bin/apxs

.....


Which had worked fine before.  However, when compiling this snapshot, I get the original errors during link time, such as:

*** Warning: linker path does not have real file for library -lxml2.
*** I have the capability to make that library automatically link in when
*** you link to this library.  But I can only do this if you have a
*** shared version of the library, which you do not appear to have
*** because I did check the linker path looking for a file starting
*** with libxml2 and none of the candidates passed a file format test
*** using a file magic. Last file checked: /lib/libdl-2.3.3.so

Thus, libphp5.so isn't created.  Seems like Joe's patch was broken somehow or somehow changed.  Any news or ideas?  Many thanks,

I think this should only happen with a broken libxml2 installation.  Do
you have both /usr/lib64/libxml2.la and /usr/lib64/libxml2.so?  The PHP
HEAD build works fine for me still.

The version of libtool bundled with PHP is very old and doesn't
correctly support x86_64 Linux (and no doubt many other platforms); you
could try a patch like below, not sure it'll make a difference though:
