Hello Dieter, Thank you for trying to help me, I really appreciate it!
I'm working on my final assignment for my bachelor. Unfortunately this means my choices are a bit limited. I'm using Code::Blocks 12.11 as my IDE and GCC 4.6.2 as my compiler. I'm more used to using C# and java, but for this assignment I need to use C++. I have some extra questions for you that I hadn't thought of before: I'm not trying to write a library. Can I only use UnitTest++ to test code that has been compiled into a library? Do you know how to get Code::Blocks to have GCC build a library with code that otherwise is intended to be run as part of a runtime? (Do I need to change anything else other than some compiler flags?) I kind of assumed that if the compiler can find the .h(pp) files, which it does (compiler errors are different if I don't do the include), it can compile the code and then link it. I'm not (really||at all) up to speed on solving linker problems, except for the most basic cases. (it seems 90% of the results that I found on google deal with missing implementations, circular inclusion and missing main functions) I hope you can help me inch my way forward. (or if anyone else knows what cures there might be, you're most welcome as well ;-) ) Yours sincerely, Onno On Mon, Jul 1, 2013 at 11:39 AM, Dieter Rosch <die...@bbd.co.za> wrote: > You need to add the library which contains the CameraLeaf code to your > linker’s input.
