Undefind reference at the time of linking

edit

Hi I am using Ubutu 12.4 and working on a catkin project. I had a package which was running successfully then I had to remove the dependency of this package from another package named sba. I did this by making some changes in CMakeList.txt and package.xml then I also copied that part of code from sba which was being used by my main package but unfortunately at the time of linking i am getting some undefined reference to "cs_di_spfree", cs_di_cholsol' andcs_di_spalloc' which do not exist in any of the file in my project. If any one can give me hint about this error that will be great... thanks..

the terminal message is copied here....
