Compiling C Programs

Compiler Return Codes

The compiler detects syntax and semantic errors during compilation and generates a return code for error conditions and warnings. These codes are summarized in Compiler Return Codes.

Compiler Return Codes
Code Meaning

0 No errors or warnings found; object code is generated.

4 Warning: object code is generated and will probably execute correctly.

8 Serious error: object code is generated but may not execute correctly.

12 Serious error: no object code is generated, and pass two of the compiler is not executed.

16 Fatal error: compilation immediately terminates.

20 Fatal error: an abend or internal compiler error occurred. Compilation stops and a dump may be produced.

***Compiler Return Codes***
Code	Meaning
0	No errors or warnings found; object code is generated.
4	Warning: object code is generated and will probably execute correctly.
8	Serious error: object code is generated but may not execute correctly.
12	Serious error: no object code is generated, and pass two of the compiler is not executed.
16	Fatal error: compilation immediately terminates.
20	Fatal error: an abend or internal compiler error occurred. Compilation stops and a dump may be produced.

Note: Under USS, the -mrc compiler option requests that the compiler return the same return codes as on OS/390 and CMS. If -mrc is not specified, the compiler conforms to UNIX conventions and returns 0 if there were no errors and a non-zero code if errors were detected. [cautionend]
