Gcc cannot be compiled to solve the problem

Compile the c source program in ubuntu for the first time and use gcc, but the following error message is prompted:
Test. c: 1: 19: Error: stdio. h: No such file or directory
Test. c: 2: 23: Error: sys/types. h: No such file or directory
Test. c: 3: 20: Error: signal. h: No such file or directory
Test. c: 4: 20: Error: ourhdr. h: No such file or directory
Basically, these files or directories are not found because the library file is not installed. Run the following command to install and solve the problem:
Sudo apt-get install libc6-dev
