I have a couple of template classes in separate libraries but when I try to link them into an executable I get errors saying that all the instances of the templates are unreferenced and the executable won't build.
Is there some system library that I have to add to the link command for templates?
I'm using Eclipse and g++ 4.4.2.
Can we see the code that you are trying to compile? And why on earth are you using Eclipse for C++? I'm guessing it's an Eclipse setup issue, I've tried on 4 separate occasions to try and setup Eclipse to work for C++ and I failed each time. I would switch to a more mainstream C++ IDE like Code::Blocks, Visual Studios, or XCode. Eclipse is mostly used for Java.
It's in the FAQ.
Basically, templates need the source code.
Thanks Yves. Now that you mention it, I do remember having this issue in the past when using templates. I've been doing Java for the past couple of years and forgot about that.
I tried using Code::Blocks but debugging with it was horrible! I'm sure that there are switches I could set to tell it to allow me to move the windows from their default location in the upper left of the screen, but it wasn't worth the hassle when Eclipse works just fine. Yes, I know it was built for Java but since I've worked with it in the past (with Java) I was familiar with the interface. I also tried NetBeans, but their C++ plugin is lacking considerably.Quote:
