Can't compile PHP 5.2.3 against IMAP

[dan@george]

Hi everyone -

I have PHP 5.0.5 running on a CentOS 4 AMD64 server right now, and I need to upgrade to PHP 5.2.3. However, since a webmail client runs on this server, the new PHP module needs to be compiled with IMAP support. Apparently the version that works with PHP 5.2.3 is imap-2006f.

So I downloaded and compiled imap-2006f and put the relevant files in /usr/include/imap-2006f. But when I try to configure PHP:

$ ./configure
...
checking whether build with IMAP works... no.
configure: error: build test failed. Please check the config.log for details.

From config.log:

...
configure:48361: checking whether build with IMAP works

I don't know where to look for the problem now. /usr/src/build doesn't even exist! Any input would be most appreciated.

Here's config.nice (which comes mostly from the old PHP 5.0.5 directory:

'./configure' \
--prefix=/home/php5 \
--with-mysql=/home/mysql \
--with-apxs2=/home/httpd-new/bin/apxs \
--with-imap=/usr/include/imap-2006f \
--with-openssl \
--with-ssl=/usr \
--with-gettext \
--with-mcrypt \
--with-zlib \
--with-gd \
--with-jpeg-dir=/usr/local \
--with-png-dir=/usr/local \
--with-freetype-dir \
--with-ttf \
--with-curl=/usr/local/lib \
"$@"

Solved this. I tried it with imap-2006g instead, and it had the same issue but more useful output. The configure script failed to find the Kerberos config program, krb5-config, and therefore couldn't figure out what version of Kerberos was installed or where it was. Kerberos is the suite that has those gss_... functions that config.log reported missing. After downloading Kerberos from MIT and installing from source, and then specifying --with-kerberos=/usr/local to PHP's configure script, everything worked.
