to compile QT client on linux you need to open and
remove these lines from the file Sexcoin-qt.pro
BOOST_LIB_SUFFIX=-mgw46-mt-sd-1_53
BOOST_INCLUDE_PATH=C:\deps\boost_1_53_0
BOOST_LIB_PATH=C:\deps\boost_1_53_0\stage\lib
BDB_INCLUDE_PATH=C:/deps/db-4.8.30.NC/build_unix
BDB_LIB_PATH=C:/deps/db-4.8.30.NC/build_unix
OPENSSL_INCLUDE_PATH=C:/deps/openssl-1.0.1b/include
OPENSSL_LIB_PATH=C:/deps/openssl-1.0.1b
then run
make distclean
qmake USE_UPNP=-
make
assuming you have all the needed libs you should be able to compile QT client now
