C++: External library in eclipse CDT

Question

Now I am using eclipse CDT for my C/C++ Application, but there is problem when I link my external library, it could not be loaded properly at run time, even through I put the library file near the source file, I gave the library path, and it's name correctly.

project directory:

1. include(.h files)
2. source(.cpp. files..)
3. lib(libbozorth3.a,LSFMatcher.a)

I want link that static libraries with my application I follow this steps:

1. project->properties->general->path and symbols->include directory path,and libraries(bozorth3.a,LSFMatcher.a),and add library path .
2. and also i add the same library in linker section also

When I build the program it displays a error cannot find -lbozorth3.a cannot find -lLSFMatcher.a

So I need the correct steps to add the external library to c/c++ application.

Solution 1

I normally configure

1. the library
2. the library search path (Needed for compiliation)
3. the runtime search path (-rpath Linker option)

(see images below and exchange the path in the Linker flags to that one you used in the library search path)

Solution 2

you should use -Wl,-rpath=${workspace_loc}/Liball and not -Wl,-rpath,${workspace_loc}/Liball.

Also under library -l option add library like eg. for libgcc.a add only gcc
