Sqlite and Eclipse, How-To, c++ [duplicate] - c++

I'm using the <XZY> IDE to compile my program, and have some trouble to import/integrate a specific library with it.
I get error messages like
fatal error: 3rdPartyLib.h: No such file or directory
for a
#include "3rdPartyLib.h"
statement
ld.exe: cannot find `lib3rdParty.a`
for specifying
3rdParty
in the additional libraries
At least I got some error message like
undefined reference to `lib3rdParty::foo()'
What can I do to fix this?


It's a common misconception, that the current IDE used, is responsible for getting errors like stated in the question.
See for example
c++ lib in two same project ,one can work but the other can 't
Issue linking libxml++ and glib libraries with CodeBlocks IDE for C++ Windows
...
The problem is almost never related to the currently used IDE.
In the most cases the solution boils down, to supply the actual toolchain's compiler/linker with the appropriate path's to search for included headers, to be linked libraries.
One of the major applicable answers for the linker related problems are
What is an undefined reference/unresolved external symbol error and how do I fix it?
undefined reference to `WinMain#16'
Most of the common IDEs provide features to configure this for a specific project. Here are some samples

All the libraries that comes with Mingw reside in the Lib directory. They are all named in the following way: lib*.a
To link a library with your project, just add in Project options, Further option files :
-lopengl32
This is for including the libopengl32.a library. To add any other library, just follow the same syntax:
Type -l (L in lowercase) plus the base name of the library (filename without lib and the .a extension).
You may also consider putting a -L option there to add directory pathes searched for libraries.
Qt Creator
In order to add include paths you have to open up the .pro file and then add
the directories to the INCLUDEPATH variable. These paths are separated by spaces. Reference can be found here.
If none of the above samples applies for your actually used IDE/toolchain, I hope you're able to get the point of abstraction:
It's an issue how to provide compiling/linking options to your actual toolchain. The IDE used to setup the context is a minor point here.


For eclipse I use the pkg-config plugin where possible:
