Which is why it complains if it has some reference to a function but you don't give it the object files (or library) which contains the real code (the function definition).Īt least when static linking. And then it replaces the function place holders with their real addresses. The job of the linker is to put all the assembler code which is distributed over object files/libraries you need in your application together. And as long as the compiler has the info those functions exist somewhere else it will trust you and put some place holder in the object files for them. The pre-processor later simply copy-pastes your header files into the cpp file at the position where your #include was. cpp file you can still reference to them if you give the compiler enough information so it knows the function name exists and the byte-size of all it's parameters. The job of the compiler is to generate object files which contain the assembler code for your. So it does not find the Irrlicht.a file.Īdding correct link_directories will fix it, but in case you want a bit longer explanation of what's going on: You probably still miss the mentioned link_directories. You can compile as soon as your include_directories are set correct (aka it finds the header files). 'ld' is the linker - so you now have a linker error. verbose, -v Enable verbose output - if supported - including the build commands to be executed.

For example, after using the Unix Makefiles generator one may run make directly: make make install Alternatively.

The Irrlicht.a will be in lib/Linux (so your linker path has to point to that and the include path to the include folder). Command to display cmake manual in Linux: man 1 cmake. Then in your CMake file set the include and linker directories both to the place you put your library. So usually you just have to run make in the source/Irrlicht folder and it will create the library (if you want also the examples to compile, which can be nice for testing, then run buildAllExamples.sh in the examples folder instead - this will build the library + all examples). Compile Irrlicht, the default is generatinbg a static library. I usually put the library somewhere beside my projects or into some sub-folder of it (or often I use soft-links to the real place which makes it easier to swap it with some other version). So download Irrlicht (preferably with svn, thought the. To have a static version you have to compile Irrlicht yourself (I forgot about that earlier as I always compile it and haven't used a distributor version in a while). Linux distrubutors tend to only package shared libraries.
