Linking static and dynamic libraries on LINUX

Question

I am trying to build an executable from different libraries using the below statement

g++ -fPIC -O -DUSING_PCH -D_REENTRANT -I"/app1/home1/quickfast/boost_1_61_0/include/boost-1_61" -I"/app1/home1/quickfast/boost_1_61_0/." -I"../../src" -I"../src/Examples" -I"/app1/home1/quickfast/boost_1_61_0/include" -L"." -L"/app1/home1/quickfast/boost_1_61_0/stage/lib" -L/app1/home1/quickfast/quickfast-master/lib -l"QuickFAST" -l"boost_thread-gcc44-mt-1_61" -l"boost_system-gcc44-mt-1_61" -l"boost_filesystem-gcc44-mt-1_61" -l"boost_unit_test_framework-gcc44-mt-1_61" -static -ldl -lpthread -o "../../bin/testSequences"

The above compilation statement includes lot of libraries, which are availabe as dynamic libaries(.so file) as well as static libraries (.a file). For example library boost_system-gcc44-mt-1_61 is present in the system as libboost_system-gcc44-mt-1_61.so as well as libboost_system-gcc44-mt-1_61.a . What I want is that while compilation only dynamic libraries (.so files) are picked up and static libraries are ignored. Can someone please guide.

You are telling it to pick up static libraries by using the -static link option. If you remove it, it'll probably work as you expect.

Yes, I meant -static and have edited the answer to reflect that. Thanks @MikeKinghan.
