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 compiling handling.

Fatal: Unexpected end of file
this typically happens in one of the following cases :
Fatal: String exceeds line
You forgot probably to include the 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 everywhere where you make a mistake 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 can be a possible source of errors.
Note: $F directive (FAR) ignored
The FAR directive is a 16-bit construction which is recorgnised but ignored by the compiler, since it produces 32 bit code.
Note: Stack check is global under Linux
Stack checking with the -Cs switch is ignored under LINUX, since LINUX does this for you. Only displayed when -vn is used.
Note: Ignored compiler switch arg1
With -vn on, the compiler warns if it ignores a switch
Warning: Illegal compiler switch arg1
You included a compiler switch (i.e. {$... }) which the compiler doesn’t know.
Warning: This compiler switch has a global effect
When -vw is used, the compiler warns if a switch is global.
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. The range is 1-255.
Fatal: Can’t open file arg1
Free Pascal cannot find the program or unit source file you specified on the command line.
Fatal: Can’t open include file arg1
Free Pascal cannot find the source file you specified in a {$include ..} statement.
Error: Too many $ENDIFs or $ELSEs
Your {$IFDEF ..} and {$ENDIF} statements aren’t balanced.
Warning: Records fields can be aligned to 1,2,4,8,16 or 32 bytes only
You are specifying the {$PACKRECORDS n} with an illegal value for n. Only 1, 2, 4, 8, 16 and 32 are valid in this case.
Warning: Enumerated can be saved in 1,2 or 4 bytes only
You are specifying the {$PACKENUM n} with an illegal value for n. Only 1,2 or 4 are valid in this case.
Error: $ENDIF expected for arg1 arg2 defined in line arg3
Your conditional compilation statements are unbalanced.
Error: Syntax error while parsing a conditional compiling expression
There is an error in the expression following the {$if ..} compiler directive.
Error: Evaluating a conditional compiling expression
There is an error in the expression following the {$if ..} compiler directive.
Warning: Macro contents is cut after char 255 to evalute expression
The contents of macros canno be longer than 255 characters. This is a safety in the compiler, to prevent buffer overflows. This is shown as a warning, i.e. when the -vw switch is used.
Error: ENDIF without IF(N)DEF
Your {$IFDEF ..} and {$ENDIF} statements aren’t balanced.
Fatal: User defined: arg1
A user defined fatal error occurred. see also the Programmers guide
Error: User defined: arg1
A user defined error occurred. see also the Programmers guide
Warning: User defined: arg1
A user defined warning occurred. see also the Programmers guide
Note: User defined: arg1
A user defined note was encountered. see also the Programmers guide
Hint: User defined: arg1
A user defined hint was encountered. see also the Programmers guide
Info: User defined: arg1
User defined information was encountered. see also the Programmers 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 it’s result was too long for the compiler.
Warning: Extension of macros exceeds a deep 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.
Error: compiler switches aren’t allowed in (* ... *) styled comments
Compiler switches should always be between { } comment delimiters.
Handling switch ”arg1”
When you set debugging info on (-vd) the compiler tells you when it is evaluating conditional compile statements.
ENDIF arg1 found
When you turn on conditional messages(-vc), the compiler tells you where it encounters conditional statements.
IFDEF arg1 found, arg2
When you turn on conditional messages(-vc), the compiler tells you where it encounters conditional statements.
IFOPT arg1 found, arg2
When you turn on conditional messages(-vc), the compiler tells you where it encounters conditional statements.
IF arg1 found, arg2
When you turn on conditional messages(-vc), the compiler tells you where it encounters conditional statements.
IFNDEF arg1 found, arg2
When you turn on conditional messages(-vc), the compiler tells you where it encounters conditional statements.
ELSE arg1 found, arg2
When you turn on conditional messages(-vc), the compiler tells you where it encounters conditional statements.
Skipping until...
When you turn on conditional messages(-vc), the compiler tells you where it encounters conditional statements, and whether it is skipping or compiling parts.
Info: Press ¡return¿ to continue
When the -vi switch is used, the compiler stops compilation and waits for the Enter key to be pressed when it encounters a {$STOP} directive.
Warning: Unsupported switch arg1
When warings are turned on (-vw) the compiler warns you about unsupported switches. This means that the switch is used in Delphi or Turbo Pascal, but not in Free Pascal
Warning: Illegal compiler directive arg1
When warings are turned on (-vw) the compiler warns you about unrecognised switches. For a list of recognised switches, Programmers guide
Back in arg1
When you use (-vt) the compiler tells you when it has finished reading an include file.
Warning: Unsupported application type: arg1
You get this warning, ff you specify an unknown application type with the directive {$APPTYPE}
Warning: APPTYPE isn’t support by the target OS
The {$APPTYPE} directive is supported by win32 applications only.
Warning: DESCRIPTION is only supported for OS2 and Win32
The {$DESCRIPTION} directive is only supported for OS2 and Win32 targets.
Note: VERSION is not supported by target OS.
The {$VERSION} directive is only supported by win32 target.
Note: VERSION only for exes or DLLs
The {$VERSION} directive is only used for executable or DLL sources.
Warning: Wrong format for VERSION directive arg1
The {$VERSION} directive format is majorversion.minorversion where majorversion and minorversion are words.
Warning: Unsupported assembler style specified arg1
When you specify an assembler mode with the {$ASMMODE xxx} the compiler didn’t recognize the mode you specified.
Warning: ASM reader switch is not possible inside asm statement, arg1 will be effective only for next
It is not possible to switch from one assembler reader to another inside an assmebler block. The new reader will be used for next assembler statement only.
Error: Wrong switch toggle, use ON/OFF or +/-
You need to use ON or OFF or a + or - to toggle the switch
Error: Resource files are not supported for this target
The target you are compiling for doesn’t support resource files. The only targets which can use resource files are Win32 and OS/2 (EMX) currently
Warning: Include environment arg1 not found in environment
The included environment variable can’t be found in the environment, it’ll be replaced by an empty string instead.
Error: Illegal value for FPU register limit
Valid values for this directive are 0..8 and NORMAL/DEFAULT
Warning: Only one resource file is supported for this target
The target you are compiling for supports only one resource file. This is the case of OS/2 (EMX) currently. The first resource file found is used, the others are discarded.
Warning: Macro support has been turned off
A macro declaration has been found, but macro support is currently off, so the declaration will be ignored. To turn macro support on compile with -Sm on the commandline or add {$MACRO ON} in the source
Warning: APPID is only supported for PalmOS
The {$APPID} directive is only supported for the PalmOS target.
Warning: APPNAME is only supported for PalmOS
The {$APPNAME} directive is only supported for the PalmOS target.
Error: Constant strings can’t be longer than 255 chars
A single string constant can contain at most 255 chars. Try splitting up the string in multiple smaller parts and concatenate them with a + operator.
