I'm trying to compile PHP 4.0.2 on TurboLinux 6.0.4 (kernel recompiled to 2.2.17).

I've configured apache and other apache modules (modssl / modauth) and now I'm trying to configure PHP.

The configure (cmd line is in debug.log, just few lines down) return exit code 0, but last lines...

The problem is libmcrypt.
I installed it correctly (./configure --disable-posix-thread --prefix=/usr ; make ; make check ; make install) and I choose version 2.4.4 (as a user note on http://www.php.net/manual/ref.mcrypt.php):

===quote
Use libmcrypt-2.2.7 with PHP <= 4.0.1pl2; or else it wouldn't compile. The reason is API of the lib has been changed. 
For libmcrypt-2.4.4 you need PHP >= 4.0.2.
===end quote

And I found this note by rasmus@php.net on Bug id #5967 "Can't compile with mcrypt"

===quote
This is a known issue.  Only mcrypt 2.2.x is supported currently [4.0.1pl2].  4.0.2 will have support
for the latest versions of mcrypt.
===end quote

So, I think I made the right thing. ;)

But debug.log reports:

It helped, can you locate libltdl on your system? It is installed when you do a make install of the mcrypt module, so it should be in /usr/lib or something. Please check if you have it installed and report back.

[2000-09-06 16:06 UTC] cerri at libero dot it

Oh, I forgot: with libmcrypt-2.2.7 all it's ok.

[2000-09-06 16:11 UTC] derick@php.net

libmcrypt 2.2.7 does not need libltdl. Do you have libltdl on your system?

A question:
before submitting the bug, I configured mcrypt to install /usr/local/lib (without --prefix). And php configure fails.
Then, I make clean mcrypt and reconfigured it with --prefix=/usr , but nothing changes.
I also included / exlcluded /usr/local/lib from ld.so.conf, but nothing.
So: libltdl is installed by mcrypt, isnt't it? And why make clean didn't deleted it? And why I only found it in /usr/local/lib and not in /usr/lib?

Thank you

On which does it fail then? I had never any problem with libmcrypt being in that directory. Actually it has been
developped with that directory.

Because make clean only deletes opject files from the build dir. Use make uninstall to uninstall the installation.
This works fine for almost every package/library.

Just add /usr/lib/local to your ld.so.conf file and run "ldconfig", now configure must be able to find both
libmcrypt en libltdl.

A question:
before submitting the bug, I configured mcrypt to install /usr/local/lib (without --prefix). And php configure fails.
Then, I make clean mcrypt and reconfigured it with --prefix=/usr , but nothing changes.
I also included / exlcluded /usr/local/lib from ld.so.conf, but nothing.
So: libltdl is installed by mcrypt, isnt't it? And why make clean didn't deleted it? And why I only found it in /usr/local/lib and not in /usr/lib?

Thank you

Sorry for the double post: my connection isn't so good today... :(

Anyway:

The debug.log was the same even I configure mcrypt with --prefix or even without (= libltdl in /usr/lib or in /usr/local/lib).

Sorry: I wrote clean instead of make uninstall / make clean .

libmcrypt en libltdl.

As I said before, I did it, and I tried to remove /usr/local/lib in ld.so.conf too, without any changes.

Anyway, I'm retrying: this is the output (snipped, of course) of ldconfig -v

/usr/local/lib:

	libmm.so.11 => libmm.so.11.0.23

Nothing: same errors.

I found the error: I downloaded an older version, even the gz was called php-4.0.2 (in NEWS there is still PHP 4.0.1).

I'm redownloading a correct version, and I'm making a test.
Of course, no problem.

Really sorry: the next time I'll download from a reliable server... 

Thank you for your support.

No big deal.

So close it.
User was using a version before 4.0.2. where libmcrypt 2.4.x was not supported.
