I am in Ubuntu. The available and popular C++ IDE is Eclipse. And since I want to go to the dubugging mode for tesseractmain.cpp (I want to look into the ocr code), it is better to use a IDE. It would be appreciated if you advice more easier options. I did not copy the missing library. The librt is in the computer. I just include the library path and file in the project properties. But it still complains, so I think I need to find and include the corresponding header. What is the header file for librt?
