Hey guys,
For those of you who want to compile earthcoin-qt in a linux distro, a little modification has to made in earthcoin-qt.pro:
Look for these lines near the end of file and apply the modifications:
# Set libraries and includes at end, to use platform-defined defaults if not overridden
INCLUDEPATH += $$BOOST_INCLUDE_PATH $$BDB_INCLUDE_PATH $$OPENSSL_INCLUDE_PATH $$QRENCODE_INCLUDE_PATH
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$$BDB_LIB_SUFFIX
-loleaut32 <---- remove if you have problems# -lgdi32 has to happen after -lcrypto (see #681)
#windows:LIBS += -lole32 -luuid -lgdi32
#LIBS += E:\MinGW\lib\libws2_32.a <------- comment it
#LIBS += E:\MinGW\lib\liboleaut32.a <------- comment it LIBS += -lboost_system$$BOOST_LIB_SUFFIX -lboost_filesystem$$BOOST_LIB_SUFFIX -lboost_program_options$$BOOST_LIB_SUFFIX -lboost_thread$$BOOST_THREAD_LIB_SUFFIX
Please dev team change it in the official repo for the linux users

Merry XMAS!
Thanks. These are residues for windows compile. We removed them and updated the source in github. Tips sent to you.
