[Boost-users] Undefined Reference (newbie) solved & followup question

From my previous post. I was linking the wrong file. The correct linkage (or at least one that compiled)

g++ test.cpp -lboost_thread-gcc-mt-d-1_33_1 A few more questions. There is also a libboost_thread-gcc-mt-d-1_33_1.so file. What is the -d represent?? Why does the linker not know to use the given library? Based on other sources I put the path /usr/local/lib in my /etc/ld.so.conf file and then ran /sbin/ldconfig What do I need to do so that I do not have to include all the boost libraries in the compile line? Thanks much. Steve
