I encounter the similiar problem yesterday (24 hours before I post this)
But just now (3 hours before I post this) , I get a fresh CVS , and fix some unicode problem in angel's sdk + annoydialog.cpp , it compile successfully .
WinXP-SP2 , wxwidgets-2.6.2-unicode.
Could it be your linker directory settings problem, I use RC2 , and manually enter the directories of compiler/linker/resource compiler y in the *newbuild.cbp.
