Understanding and Handling Compiler Errors
2-37 C Compiler Description
Table 2 − 3. Example Error Messages
Error Level Example Error Message

Code F
”file.c”, line 71: [F0108] structure member ’a’ undefined
Code I

Other
>> Cannot open source file ’mystery.c’
2.8.1 Generating an Error Listing ( − pr Option)
Use the − pr option to generate an error listing. The error listing has the name
source . err , where source is the name of the C source file.
2.8.2 Treating Code-E Errors as Warnings ( − pe Option)
A fatal error prevents the compiler from generating an output file. Normally,
code-E, -F, and -I errors are fatal, while -W errors are not. The − pe option
causes the compiler to treat code-E errors as warnings, so that the compiler
generates code for the file despite the error.
Using − pe allows you to bend the rules of the language, so be careful; as with
any warning, the compiler might not generate what you expect.
There is no way to specify recovery from code-F or -I errors. These errors are
always fatal.
See section 2.8.4, An Example of How You Can Use Error Options , for an ex-
ample of the − pe option.
2.8.3 Altering the Level of Warning Messages ( − pw Option)
You can determine which levels of warning messages to display by setting the
warning message level with the
− pw option. The number following − pw
denotes the level (0,1, or 2). Use Table 2 − 4 to select the appropriate level. See
section 2.8.4, An Example of How You Can Use Error Options , for an example
of the − pw option.
