This definition has to be available for the compiler to actually build the function from the template using the desired type for T. It is a kind of declaration similar to the prototype you placed in your header file. Just tell the compiler how the function should be built. Attachment: TypicalBuildLogInAConsoleView.png.you should see -L -larray on the linker line with as the actual path. button to specify a file in the current workspace (assuming both projects are in the same workspace and the project files are in the workspace). Since it is in another project you can use the the Worlspace. GCC will not complain about incorrect path names. My guess is (if the name is libarray.a) you haven't provided the proper path with the -L option. You say you built the library so you must know the full path to it. Please post the full path to your library as well as its complete name. L/home/dvavra/proj/PNL/high/source/.libs The others could have been specified using -L and -l, for example: /home/dvavra/proj/PNL/high/source/.libs/libhigh.a could have been specified by Specifying lib files in CDT is sometimes tricky as the position order can be significant. I had to do this because they don't follow the libXXX.a naming convention. Note how I specified obj/nblib.a and obj/locallib.a. It should be near the bottom of the build log which should be appearing in a console view during the build. I still need to see what the link command actually is being used. OK, Simone, just to be sure, the name of the library you are looking for is libarray.a ? If it isn't you can't use -larray to link it. Attachment: Schermata del 19:17:11.png.I hope you can understand the language because It's written in Italian. So I ask if you can tell me what I have to do to link my library. I included the library (#include "array.h") and I made all that i could make in project properties to link the library in test_lab1.cpp but now the compiler shows me error that it can't find the library. So I created another project called "test_lab1.cpp" where I'd like to test the functions that I implemented in my library. I built the library and all it's ok as the compiler doesn't show me error. Then I created two files: array.h, where I wrote the prototype of functions, and array.cpp where I implemented my functions and I included array.h ( #include "array.h"). I selected static library, empty project, called the project name lab1 (as it's an exercise for university) and I selected the toolchains "Linux GCC". First of all in eclipse I created a new C++ project.
