c – 与libQt5Core的联系

我的makefile是：

CPPFLAGS=-g -c --std=c++0x -I/usr/include -I/home/bush/Qt/5.4/gcc_64/include -I/home/bush/Qt/5.4/gcc_64/include/QtCore -I/usr/include/boostLDFLAGS=-g -L/home/bush/Qt/5.4/gcc_64/lib -L/usr/lib/x86_64-linux-gnu/ -lQt5Core -lboost_system -lpthreadall:partyparty:test.o Party.o Communication.o fileParser.o PeerConnection.o ServerModule.o UtilitIEs.o    g++ -Wall $^ -o party $(LDFLAGS)test.o:test.cpp    g++ $(CPPFLAGS) test.cppParty.o:Party.cpp    g++ $(CPPFLAGS) Party.cppCommunication.o:Communication.cpp    g++ $(CPPFLAGS) Communication.cppfileParser.o:fileParser.cpp    g++ -fPIC $(CPPFLAGS) fileParser.cppPeerConnection.o:PeerConnection.cpp    g++ $(CPPFLAGS) PeerConnection.cppServerModule.o:ServerModule.cpp    g++ $(CPPFLAGS) ServerModule.cppUtilitIEs.o:UtilitIEs.cpp    g++ $(CPPFLAGS) UtilitIEs.cpp

解决方法 我遇到了同样的问题.但是我通过这个代码找到我的出路.

export  LD_liBRARY_PATH=/usr/local/Qt/5.5/gcc_64/lib:$LD_liBRARY_PATH
