Im assuming the same linking errors but im not sure. dub doesn't download library binaries, but the source. It compiles each dependency along with your project (generally only once, unless you --force a rebuild or -upgrade the libraries) using the same compiler that is used to compile your source. So if any given library is using something that is unavailable on your platform, you will see compile-time errors rather than linker errors. --- This email is free from viruses and malware because avast!

OSX, Need help with Compiling and linking errors
Ive been reading the OSX notes for the DMD compiler but not everything is clear to me as i dont know how exactly the compiler looks for things. i wanted to test it out first using this package from code.dlang.org http://code.dlang.org/packages/colorize I downloaded the zip, extracted it, and dub was able to spit out a static library with the .a extension. What do i do with it now? Where do i place it? I have imported the library like it says import colorize : colorize, fg; After i call dmd in the terminal like $ dmd main.d, All i get are linker errors but no compile errors even if i reference the static library in the same drectory as my main.d source file like so, $ dmd main.d libcolorize.a Then the package mentions adding colorize as a dependency to my projects json file so i used the -X switch to generate it but i dont know exactly where the dependencies section goes. As for the linker errors, they mention mostly: === Undefined symbols for architecture x86_64: _D4dlib4math6matrix16__T6MatrixTdVi4Z6Matrix11__xopEqualsFKxS4dlib4math6matrix16__T6MatrixTdVi4Z6MatrixKxS4dlib4math6matrix16__T6MatrixTdVi4Z6MatrixZb, referenced from: _D52TypeInfo_S4dlib4math6matrix16__T6MatrixTdVi4Z6Matrix6__initZ in main.o ld: symbol(s) not found for architecture x86_64 === Does this mean this library is just not compatible with OSX? Extra Notes: I have Xcode Installed along with the command line tools so GCC is in there too. OSX 10.9.4 X11 - XQuartz

That is a dlib.math.matrix module. Is that a source module in your project or something from another library? If the former, you need to be compiling it along with your main.d. If the latter, you need to be linking with that library. However, I recommend you avoid using dmd on the command line for now and just use dub to manage your project (see below). This has nothing to do with the json generated by DMD. It's referring to a dub.json which is a project configuration file for dub. If you create a dub.json, then you can run dub or dub build in your project directory and it will automatically compile all of your source modules and make sure that all of your dependencies (such as libcolorize) are downloaded, compiled and link. It's a complete build and package management system. You don't need to download your dependencies manually or compile from the command line if you are using dub. You can read more about the dub.json format at [1]. [1] http://code.dlang.org/package-format Awesome thanks. Sorry about that linker error, i copied and posted the wrong error from a previous compile trial. Anyways i managed to fix my problem and my static libraries now compile without errors. I will play with dub a little bit more. Thanks. I just thought i would learn from the beginning compiling and linking manually within the terminal. I had no idea dub could do all that for me. What about the dub libraries, what kind of errors do you get if you try to use a library not compatible for your system, say OSX or Linux? Im assuming the same linking errors but im not sure.
