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. rtld: 0712-001 Symbol i_stream_get_data was referenced from module /usr/local/lib/dovecot/imap/lib20_zlib_plugin.so(), but a runtime definition of the symbol was not found. rtld: 0712-001 Symbol i_stream_skip was referenced from module /usr/local/lib/dovecot/imap/lib20_zlib_plugin.so(), but a runtime definition of the symbol was not found. rtld: 0712-001 Symbol i_stream_seek was referenced from module /usr/local/lib/dovecot/imap/lib20_zlib_plugin.so(), but a runtime definition of the symbol was not found. rtld: 0712-001 Symbol i_stream_close was referenced from module /usr/local/lib/dovecot/imap/lib20_zlib_plugin.so(), but a runtime definition of the symbol was not found. rtld: 0712-001 Symbol i_panic was referenced from module /usr/local/lib/dovecot/imap/lib20_zlib_plugin.so(), but a runtime definition of the symbol was not found. rtld: 0712-001 Symbol pool_get_exp_grown_size was referenced from module /usr/local/lib/dovecot/imap/lib20_zlib_plugin.so(), but a runtime definition of the symbol was not found.
