C++: External library in eclipse CDT

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:

include(.h files)

source(.cpp. files..)

lib(libbozorth3.a,LSFMatcher.a)

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

project->properties->general->path and symbols->include directory path,and libraries(bozorth3.a,LSFMatcher.a),and add library path .

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.

---

I normally configure

the library

the library search path (Needed for compiliation)

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)

---

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

---

You should pay attention to what is in parentheses: Other options (-Xlinker [option]).

The way to pass options is different. Instead of using:

-Wl,-rpath,'${ProjDirPath}/../../system/lib'

You must use:

-rpath '${ProjDirPath}/../../system/lib'

That is, remove the "-Wl," and replace the second "," by " " (space).
