Scanner messages.

C.2 Scanner messages.

This section lists the messages that the scanner emits. The scanner takes care of the lexical structure of the pascal file, i.e. it tries to find reserved words, strings, etc. It also takes care of directives and conditional compilation handling.

Fatal: Unexpected end of file

This typically happens in one of the following cases:

The source file ends before the final end. statement. This happens mostly when the begin and end statements are not balanced;
An include file ends in the middle of a statement.
A comment was not closed.

Fatal: String exceeds line

There is a missing closing ’ in a string, so it occupies multiple lines.

Fatal: illegal character ”arg1” (arg2)

An illegal character was encountered in the input file.

Fatal: Syntax error, ”arg1” expected but ”arg2” found

This indicates that the compiler expected a different token than the one you typed. It can occur almost anywhere it is possible to make an error against the Pascal language.

Start reading includefile arg1

When you provide the -vt switch, the compiler tells you when it starts reading an included file.

Warning: Comment level arg1 found

When the -vw switch is used, then the compiler warns you if it finds nested comments. Nested comments are not allowed in Turbo Pascal and Delphi, and can be a possible source of errors.

Note: Ignored compiler switch ”arg1”

With -vn on, the compiler warns if it ignores a switch.

Warning: Illegal compiler switch ”arg1”

You included a compiler switch (i.e. {$... }) which the compiler does not recognise.

Warning: Misplaced global compiler switch, ignored

The compiler switch is misplaced. It must be located at the start of the compilation unit, before the uses clause or any declaration.

Error: Illegal char constant

This happens when you specify a character with its ASCII code, as in #96, but the number is either illegal, or out of range.

Fatal: Cannot open file ”arg1”

Free Pascal cannot find the program or unit source file you specified on the command line.

Fatal: Cannot open include file ”arg1”

Free Pascal cannot find the source file you specified in a {$include ..} statement.

Error: Illegal record alignment specifier ”arg1”

You are specifying {$PACKRECORDS n} or {$ALIGN n} with an illegal value for n. For $PACKRECORDS valid alignments are 1, 2, 4, 8, 16, 32, C, NORMAL, DEFAULT, and for $ALIGN valid alignments are 1, 2, 4, 8, 16, 32, ON, OFF. Under mode MacPas $ALIGN also supports MAC68K, POWER and RESET.

Error: Illegal enum minimum-size specifier ”arg1”

You are specifying the {$PACKENUM n} with an illegal value for n. Only 1,2,4, NORMAL or DEFAULT is valid here.

Error: $ENDIF expected for arg1 arg2 defined in arg3 line arg4

Your conditional compilation statements are unbalanced.

Error: Syntax error while parsing a conditional compiling expression

There is an error in the expression following the {$if ..}, {$ifc } or {$setc } compiler directives.

Error: Evaluating a conditional compiling expression

There is an error in the expression following the {$if ..}, ifcorsetc compiler directives.

Warning: Macro contents are limited to 255 characters in length

The contents of macros cannot be longer than 255 characters.

Error: ENDIF without IF(N)DEF

Your {$IFDEF ..} and {$ENDIF} statements are not balanced.

Fatal: User defined: arg1

A user defined fatal error occurred. See also the Programmer’s Guide.

Error: User defined: arg1

A user defined error occurred. See also the Programmer’s Guide.

Warning: User defined: arg1

A user defined warning occurred. See also the Programmer’s Guide.

Note: User defined: arg1

A user defined note was encountered. See also the Programmer’s Guide.

Hint: User defined: arg1

A user defined hint was encountered. See also the Programmer’s Guide.

Info: User defined: arg1

User defined information was encountered. See also the Programmer’s Guide.

Error: Keyword redefined as macro has no effect

You cannot redefine keywords with macros.

Fatal: Macro buffer overflow while reading or expanding a macro

Your macro or its result was too long for the compiler.

Warning: Expanding of macros exceeds a depth of 16.

When expanding a macro, macros have been nested to a level of 16. The compiler will expand no further, since this may be a sign that recursion is used.

Warning: compiler switches are not supported in // styled comments

Compiler switches should be in normal Pascal style comments.

Handling switch ”arg1”

When you set debugging info on (-vd) the compiler tells you when it is evaluating conditional compile statements.

ENDIF arg1 found
