Problems adding a new library .a
I've had the same problem. When I tried to compare to a project that would both compile and link with the same library - I noticed that in the project that would link in the library the library name was prefixed with : so in the properties the correct library name was 😕TemWin_CM7_GCC_ARGB.a instead of STemWin_CM7_GCC_ARGB.a ! Notice also, that I kept the .a suffix - otherwise the linker can not find the library!
