Plugins Support on AIX
======================
/How to build Dovecot with plugins supported on AIX./
Tested with:
* AIX 5.2, VAC 5.0.2 and Dovecot 1.0rc21 to 1.0.13 /(Dovecot 1.1.x does not
build with VAC 5.0.2)/
* AIX 5.2, VAC 8.0.0 and Dovecot 1.1.1
The Problem
-----------
* When you trying to use plugins on AIX you seen error messages like this:
---%<----------------------------------------------------------------------
imap(root): Error:
dlopen(/usr/local/lib/dovecot/imap/lib20_zlib_plugin.so) failed:
rtld: 0712-001 Symbol i_error was referenced
from module /usr/local/lib/dovecot/imap/lib20_zlib_plugin.so(),
but a runtime definition of the symbol was not found.

Additional errors occurred but are not reported.

Compiler Script
---------------
* Create a compiler script to rewrite the /xlc/ command line on the fly:
*dovecot-cc*
---%<----------------------------------------------------------------------
#!/bin/bash
xlc=/usr/bin/xlc

Compiling Dovecot
-----------------
* Expand Dovecot:
---%<----------------------------------------------------------------------
gzip -cd doveccot-1.0.rc21.tar.gz | tar xvf -
---%<----------------------------------------------------------------------
* Setup build environment:
---%<----------------------------------------------------------------------
export CC=$PWD/dovecot-cc
export LDFLAGS="-bexpall -brtl"
---%<----------------------------------------------------------------------
* Configure and build Dovecot
---%<----------------------------------------------------------------------
cd dovecot-1.0.rc21
bash configure
make
---%<----------------------------------------------------------------------
* Test a plugin (e.g. zlib)
---%<----------------------------------------------------------------------
echo 0 logout | MAIL_PLUGIN_DIR=src/plugins/zlib/.libs/ MAIL_PLUGINS="zlib"
MAIL=maildir:/tmp src/imap/imap
---%<----------------------------------------------------------------------
you should see this:
---%<----------------------------------------------------------------------
* PREAUTH [CAPABILITY IMAP4rev1 SASL-IR SORT THREAD=REFERENCES MULTIAPPEND
UNSELECT LITERAL+ IDLE CHILDREN NAMESPACE LOGIN-REFERRALS] Logged in as root
* BYE Logging out
0 OK Logout completed.

---%<----------------------------------------------------------------------
* Install Dovecot
---%<----------------------------------------------------------------------
make install
