You don't want to do it in Qt creator. You want to install the command line bits and do it that way. Trust me, I tried for WEEKS to get this to work in the creator. I've made it exceedingly easy to compile for windows with this guide:
http://devtome.com/doku.php?id=scrypt_altcoin_cloning_guide#windows_-qtThe list of things you should install (MinGW, QT Command-line, Perl) and links to them are in the guide.
For the dependecnies, you can download my pre-compiled dependencies here:
https://github.com/foocoin/deps/archive/master.zipThe zip should be placed as c:\deps.
Now, open your -qt.pro with Notepad or whatever, and replace this line:
DEFINES += QT_GUI BOOST_THREAD_USE_LIB BOOST_SPIRIT_THREADSAFE
with this one:
DEFINES += QT_GUI BOOST_THREAD_USE_LIB BOOST_SPIRIT_THREADSAFE BOOST_THREAD_PROVIDES_GENERIC_SHARED_MUTEX_ON_WIN __NO_SYSTEM_INCLUDES
Its right at the top, very easy to find, 4th or 5th line down. Now right under that there will be a section that looks like this:
# Dependency library locations can be customized with:
# BOOST_INCLUDE_PATH, BOOST_LIB_PATH, BDB_INCLUDE_PATH,
# BDB_LIB_PATH, OPENSSL_INCLUDE_PATH and OPENSSL_LIB_PATH respectively
Replace that with this:
windows:LIBS += -lshlwapi
LIBS += $$join(BOOST_LIB_PATH,,-L,) $$join(BDB_LIB_PATH,,-L,) $$join(OPENSSL_LIB_PATH,,-L,) $$join(QRENCODE_LIB_PATH,,-L,)
LIBS += -lssl -lcrypto -ldb_cxx$$BDB_LIB_SUFFIX
windows:LIBS += -lws2_32 -lole32 -loleaut32 -luuid -lgdi32
LIBS += -lboost_system-mgw46-mt-sd-1_53 -lboost_filesystem-mgw46-mt-sd-1_53 -lboost_program_options-mgw46-mt-sd-1_53 -lboost_thread-mgw46-mt-sd-1_53
BOOST_LIB_SUFFIX=-mgw46-mt-sd-1_53
BOOST_INCLUDE_PATH=C:/deps/boost
BOOST_LIB_PATH=C:/deps/boost/stage/lib
BDB_INCLUDE_PATH=c:/deps/db/build_unix
BDB_LIB_PATH=c:/deps/db/build_unix
OPENSSL_INCLUDE_PATH=c:/deps/ssl/include
OPENSSL_LIB_PATH=c:/deps/ssl
MINIUPNPC_LIB_PATH=c:/deps/miniupnpc
MINIUPNPC_INCLUDE_PATH=c:/deps
Then you'll be able to do the "qmake" and "make -f Makefile.Release" as listed in the step by step guide.
I'm happy to walk you through this in irc if you'd like, my BTC addy is in my sig.
