mysqlclient.lib(default.obj) : error LNK2001: unresolved external symbol __iob...help

[Arex]

i am trying compile eqemu using visual c++ 2005 Express, and all looks go good, but on linking phase, i get the next messagge when i try build zoneperl:

------ Build started: Project: Zone, Configuration: ReleasePerl Win32 ------
Linking...
mysqlclient.lib(my_thr_init.obj) : error LNK2019: unresolved external symbol __iob referenced in function _my_thread_global_init

mysqlclient.lib(my_messnc.obj) : error LNK2001: unresolved external symbol __iob
../build/ZonePerl.exe : fatal error LNK1120: 1 unresolved externals
Build log was saved at "file://c:\Documents and Settings\Tornar\Mis documentos\EQEMU\EQEmu-0.6.4-DR1-612\zone\Zone___Win32_ReleasePerl\BuildLog.htm"
Zone - 4 error(s), 0 warning(s)

any idea? plz, i already have added all include, lib, etc. paths like eqemu wikki says..
