Info

file is given the same name as the input file, except with the filename extension ".R". Unless the explicitly defines some other filename extension, the extension ".R" will automatically be appended by the Assembler. -q= This option is used to assign a numeric class specifier to the relocatable module produced by the compiler. The class specifier assigned is determined by the entry, which can be any number from zero through 255. If this option is not specified, the relocatable output module produced by the Assembler will be assigned the default class number of zero ("0"). A module's class number becomes significant when multiple modules exist which have identical "filenames"; in such instances, use of a different class number for each such module permits any given module to be uniquely identifiable. -u -X This option forces all undefined symbols to default to imported symbols. When this option is not specified, any symbol which is not imported and also not defined within the file will generate an error message. This option prevents an object file from being produced. C.4.6
<strong>COMPILER</strong> ERROR MESSAGES Compiler error messages typically occur because of one of three basic types of "errors" being encountered during compilation. The most common cause of an error message is that a syntax error of some type has been detected in the C source input file. A second type of error is when the Compiler cannot, for some reason, perform its compilation; for example, if the disk becomes full while the Compiler is attempting to write out one of its many temporary files. The third type of error is one in which the Compiler fails to operate due to an internal bug. This last type of error should, of course, never occur but a realist should not be totally unprepared for such a possibility. Program error messages have the form: file: error at line where is the name of the file involved, is the line number in that file at which an error became apparent to the Compiler, and is a note from the Compiler which indicates what the Compiler found unacceptable. Notice that the line number given is the line in which a syntax error of some type first became evident to the Compiler. This may or may not be the actual line in the file where the program first began deviating from what the programmer may have had in mind when he was writing it. There is really no way for the Compiler to guess what the "real" error in a program may be; the Compiler can only complain at the point where the program text subsequently becomes syntactically incorrect. This may be many lines after the line which contains the actual programming error. Similarly, the message which the Compiler prints out indicates what the Compiler sees the problem to be; this may or may not be the problem as the programmer sees it. The following are some explanations of the less obvious error messages produced by the Compiler. 'while' expected The Compiler expected a "while" to follow a "do" but instead found something else. arithmetic type required The Compiler expected an expression which evaluated to an arithmetic type, but instead found something else such as a structure or union. bad & The ampersand operator was used on something which was not an lvalue. bad break A break was encountered which was not in either a "do", "while", or "for" loop, or in a "switch" statement.
