I am running a C++ tutorial program using Codeblocks and I found out that in the program's build options under Linker settings/Link Libraries I can put both or either of the ff and the program compiles & runs without errors. What is the difference between the two?
libboost_filesystem-mgw8-mt-d-x64-1_77.dll.a
OR
libboost_filesystem-mgw8-mt-x64-1_77.dll.a
