Linux eclipse unresolved injection sion

Another problem encountered today is that the same error occurs in include <sys/types. h>.

Solution: copy the Sys folder to the/usr/include folder. The problem is solved.

I just got started with Linux and used ubuntu11.10 to programming with IDE. Eclipse CDT is powerful. After installation, C ++ can be compiled and run.ProgramBut there is a problem, that is, the header file of the C ++ standard library cannot be found, and files such as <iostream> cannot be opened. The compiler warning is as follows:

Display

Unresolved regression sion: <iostream>

Although compilation is not affected, the symbols in the header file cannot be located. The reason is that the C and C ++ directories of eclipse are not specified. You can specify the header file directory by setting the c_include_path and cpp_include_path environment variables in eclipse.

Add these two variables to WINDOW> preferences> C/C ++> environment:

Set c_include_path to/usr/include

Set cpp_include_path to/usr/include/C ++/4.6.1

4.6.1 is the GCC version, which can be obtained using gcc -- version. You can change it to the corresponding version.

After these two variables are added, eclipse can normally identify the header files of the C ++ standard library. Eclipse adds all the nodes files to the project.
