Adding a library confuses the compiler :(

[cariacou]

Hello.

I am trying to write a simple cpp code using an external API.
I am having issues with the compiling syntax.
When adding a library, which quotes should I use ? ", ', < ?
should I add it in the 3 different options:
- C++ compiler/includes (-I)
- C++ linker / libraries (-l)
- c++ library search path (-L)

?

I use Eclipse 3.5 / win7 64 / mingw.

here is the result of the compiler:

**** Build of configuration Debug for project FindUSBDevices0 ****

**** Internal Builder is used for build               ****

you should add the absolute path to your library to your path variable on your computer. Use this http://www.java.com/en/download/help/path.xml

Personally I've only worked with header files so there is no need for the above procedure; because you just have to have the header file in the same directory of your main project then to include it, you use:

#include "myheader.h"

And yes the extension of the file has to be .h
