Undefined reference to...
I'm trying to compile and try some libraies to decodify a datamtatrix code. I'm using codeblocks over Windows XP.
I have tried with two libraries and I always get the same error: undefined reference to... I have seen that is a linker problem, but I don't know how to fix it.
In the first library. I compile it perfectly and it works. But the problems come when I want to add one file that it's need to open a file from the HDD. So, when I add it, it needs some libraries like magick wand and magick (about images). I add them and I finish of compile it perfectly. But then, it says "undefined reference to..." each function called by dtmxread to the magick wand library.
In the second one, it happens the same. This one need to be linked by Fec.h. When I finish of compile it, the linker erros comes to me againg. Each function called in the library to the file fec.h are undefined references...
What I'm doing wrong? Thank you so much.
Should I use anothe programming enviroment?.
