The Intel® C/C++ Error Parser (selected by default) lets you track compile-time errors in Eclipse*/CDT. To confirm that the Intel® C/C++ Error Parser is active:
The Intel® C/C++ Error Parser automatically detects and manages the diagnostics generated by the Intel® oneAPI DPC++/C++ Compiler.
If an error occurring in the hello_world.c program is compiled, for example, #include <xstdio.h>, the error is reported in the Problems view next to an error marker.
You can double-click on each error in the Problems view to highlight the source line, which causes the error in the Editor view.
Correct the error, then rebuild your project.
