Description:
Am trying to compile myql into php with the imap c-client.  php doesn't like something when it tries linking everything together.  the php dev list has sent it back saying it's not a bug with their code.  

http://bugs.php.net/bug.php?id=31182

I've already created a bug report/request with the c-client developers.  Just wanting to make sure that it's something or nothing that can be done with mysql.  Everything works fine with mysql 4.0.x and lower versions.  just the 4.1.7/8 so far.  

How to repeat:
With php 5.0.2/3: 

'./configure' \
'--with-mysql' \
'--with-imap=/usr/local/imap-2004a' \
'--with-imap-ssl' \
"$@"

then a make will produce:

/usr/local/imap-2004a/lib/libc-client.a(misc.o)(.text+0x8a4): In
function `hash_reset':
/build/imap-2004a/c-client/misc.c:278: multiple definition of
`hash_reset'
/usr/lib/mysql/libmysqlclient.a(hash.o)(.text+0x130): first defined
here
/usr/bin/ld: Warning: size of symbol `hash_reset' changed from 94 in
/usr/lib/mysql/libmysqlclient.a(hash.o) to 89 in
/usr/lib/mysql/libmysqlclient.a(hash.o)
collect2: ld returned 1 exit status
make: *** [libphp5.la] Error 1

Suggested fix:
The mysql library and/or imap library need to
name-space protect their symbols. Please file a bug with them.

Using 4.1.6 this problem doesn't occur.

I've experience the same problem with MySQL 4.1.7  and 4.1.8 as well as the new IMAP 2004b RC2.

If its not something that has to do with mysql, then its definitely something that newer versions of mysql trigger when compiling.  I have a setup with php4.3.10 and imap-client.  Using mysql 4.13 this compiled and worked fine.  All i have done upgraded mysql to 4.18 and now re-building php 4.3.10 is causing this error.

I am experiencing this problem as well.  On Solaris 8 using 4.1.8 mysql, 2004a imap from University of Washington, and php.

I was able to fix/patch this by modifying the files for imapd.

# cd imap-2004b/
# find . -type f -exec sed -i "s/hash_reset/FIX_hash_reset/g" {} \;
# make ???
# mkdir lib
# mkdir include
# cp c-client/*.h include
# cp c-client/*.c lib
# cp c-client/c-client.a lib/libc-client.a
# cd /dir/to/php/src
# make clean
# ./configure --with-apxs2 --with-mysql --with-imap=../where_i_just_was/imap-2004b --with-imap-ssl=/dir/to/openssl

Fixed in 4.1.9,
