Install error: undefined symbol: uncompress

Anon

I am trying to install PHP4 on a machine that is running Linux 6.0(I think) and apache 1.3.6.

I used the following config command:
.configure --with-apxs=/usr/sbin/apxs --with-mysql=/usr/local/mysql-3.23.27-beta-pc-linux-gnu-i686

then I a did a make;make install

then I edited the httpd.conf file and added:
LoadModule php4_module modules/libphp4.so
AddModule mod_php4.c

and when I issue the restart command to apache I get the following error:

Cannot load /etc/httpd/modules/libphp4.so into server: /etc/httpd/modules/libphp4.so: undefined symbol: uncompress

Any suggestions?

Thanks,
Jeff

First upgrade your Apache; it's very old and even contains security problems.

I think that the Apache-module version of PHP now requires that your Apache is at least v. 1.3.9. Upgrading to Apache 1.3.14 is the only sane upgrade, though.

If you still get trouble after upgrading Apache, then re-post your question.

May I ask your help upgrade Apache? 1.3.9 is running what I would hate ruin.
Besides PhP4 does not accept httpd.h although the exact dir is given in --with-apache=/dir

I recommend that you upgrade to the official, updated Apache (1.3.14) for Red Hat 6.x:
http://ftp.sunet.se/pub/os/Linux/distributions/redhat/updates/6.2/i386/apache-1.3.14-2.6.2.i386.rpm

A good reason to upgrade is that your Apache contains some know security problems.

Why do you want to compile it yourself, by the way?
Consider using ready-to-run packages:

Troels,
Thanks and oke. My Linux is Suse 6.3. Should I try with Red Hat apache?
Well, Suse was installed by a guy I cannot ask again to help, in a word I am afraid of ruining something that works.
However I am not against it.

SuSE has probably released an updated Apache package which will fit your system.

Hi,

I think that your problem has nothing to do with your apache version.
It has something to do with the mysql client library.
I had the same problem and this is how I solved it:

The mysql client library needs the uncompress function provided by libz. If you compile mysql all static the libz library doesn't get compiled in (a bug?).

Solutions:

(1) Recompile mysql and check that the Makefile of the mysql client contains "-lz" in the line containing the linker options
like -lmysqlclient. I didn't verify this yet because I chose to do it the second way in my case.

(2) recompile php4. After executing the configure script find all Makefiles that contain -lmysqlclient and ensure that those lines also contain -lz (add it manually if neccessary). Then do the make,
make install.

(If you compile php4 with the configure parameter --with-apache then one of the files in the directory <apache-src>/src/modules/php4 contains the linker options. Make sure that it contains the -lz argument, too.)

Important: If you do it the second way then all tools and software using the mysql client has to be checked for the -lz argument (especially the Msql-Mysql perl modules!).

I think that there are easier solutions but this one did it for me.

Greetings,
Thomas

Actually i found a much easier solution at http://www.mysql.com/doc/L/i/Link_errors.html

quoting them:

If you get undefined reference errors for the uncompress or compress function, add -lz last on your link line and try again!

It was pretty simple to add "-lz" to the LIBS1 line in apache_1.3.19/src/Makefile and then the Apache make was happy. In fact i had only MySQL binaries installed so there would be no way for me to rebuild mysql.

HTH.

I've spend days trying to get apache + php + mysql + mod_ssl to work together.

There were several problems but the one mentioned in this topic was the most difficult to solve. I found the same answer as you mentioned in the MySQL forums, but didn't know exactly where to add '-lz'.

Your post finally solved it. Thank you very much.

I feel this should be described more thoroughly in the MySQL and PHP FAQ to ensure other people don't have to go through the same frustrating process trying to solve this problem.
