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:
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. {$... }) which the compiler does not recognise.
Warning: Misplaced global compiler switch
The compiler switch is misplaced, and should be located at the start of the unit or program.
Error: Illegal char constant
This happens when you specify a character with its ASCII code, as in #96, but the number is either illegal, or out of range.
Fatal: Can’t open file ”arg1”
Free Pascal cannot find the program or unit source file you specified on the command line.
Fatal: Can’t open include file ”arg1”
Free Pascal cannot find the source file you specified in a {$include ..} statement.
Error: 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 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 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 aren’t 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
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 warnings 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 warnings are turned on (-vw), the compiler warns you about unrecognised switches. For a list of recognised switches, see the Programmers guide.
Back in arg1
When you use the -vt switch, the compiler tells you when it has finished reading an include file.
Warning: Unsupported application type: ”arg1”
You get this warning if you specify an unknown application type with the directive {$APPTYPE}.
Warning: APPTYPE is not supported by the target OS
The {$APPTYPE} directive is supported by certain operating systems only.
Warning: DESCRIPTION is not supported by the target OS
The {$DESCRIPTION} directive is not supported on this target OS.
Note: VERSION is not supported by target OS
The {$VERSION} directive is not supported on this target OS.
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.
Error: Illegal assembler style specified ”arg1”
When you specify an assembler mode with the {$ASMMODE xxx} directive, the compiler didn’t recognize the mode you specified.
Warning: ASM reader switch is not possible inside asm statement, ”arg1” will be effective only for next
It is not possible to switch from one assembler reader to another inside an assembler block. The new reader will be used for next assembler statements only.
Error: Wrong switch toggle, use ON/OFF or +/-
You need to use ON or OFF or a + or - to toggle the switch.
Error: Resource files are not supported for this target
The target you are compiling for doesn’t support resource files.
Warning: Include environment ”arg1” not found in environment
The included environment variable can’t be found in the environment; it will be replaced by an empty string instead.
Error: Illegal value for FPU register limit
Valid values for this directive are 0..8 and NORMAL/DEFAULT.
Warning: Only one resource file is supported for this target
The target you are compiling for supports only one resource file. The first resource file found is used, the others are discarded.
Warning: Macro support has been turned off
A macro declaration has been found, but macro support is currently off, so the declaration will be ignored. To turn macro support on compile with -Sm on the command line or add {$MACRO ON} in the source.
Error: Illegal interface type specified. Valids are COM, CORBA or DEFAULT.
The interface type that was specified is not supported.
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 into multiple smaller parts and concatenate them with a + operator.
Fatal: Including include files exceeds a depth of 16.
When including include files the files have been nested to a level of 16. The compiler will expand no further, since this may be a sign that recursion is used.
Fatal: Too many levels of PUSH
A maximum of 20 levels is allowed. This error occurs only in mode MacPas.
Error: A POP without a preceding PUSH
This error occurs only in mode MacPas.
Error: Macro or compile time variable ”arg1” does not have any value
Thus the conditional compile time expression cannot be evaluated.
Error: Wrong switch toggle, use ON/OFF/DEFAULT or +/-/*
You need to use ON or OFF or DEFAULT or a + or - or * to toggle the switch.
Error: Mode switch ”arg1” not allowed here
A mode switch has already been encountered, or, in the case of option -Mmacpas, a mode switch occurs after UNIT.
Error: Compile time variable or macro ”arg1” is not defined.
Thus the conditional compile time expression cannot be evaluated. Only in mode MacPas.
Error: UTF-8 code greater than 65535 found
Free Pascal handles UTF-8 strings internally as widestrings, i.e. the char codes are limited to 65535.
Error: Malformed UTF-8 string
The given string isn’t a valid UTF-8 string.
UTF-8 signature found, using UTF-8 encoding
The compiler found a UTF-8 encoding signature ($ef, $bb, $bf) at the beginning of a file, so it interprets it as a UTF-8 file.
Error: Compile time expression: Wanted arg1 but got arg2 at arg3
The type-check of a compile time expression failed.
Note: APPTYPE is not supported by the target OS
The {$APPTYPE} directive is supported by certain operating systems only.
Error: Illegal optimization specified ”arg1”
You specified an optimization with the {$OPTIMIZATION xxx} directive, and the compiler didn’t recognize the optimization you specified.
Warning: SETPEFLAGS is not supported by the target OS
The {$SETPEFLAGS} directive is not supported by the target OS.
Warning: IMAGEBASE is not supported by the target OS
The {$IMAGEBASE} directive is not supported by the target OS.
Warning: MINSTACKSIZE is not supported by the target OS
The {$MINSTACKSIZE} directive is not supported by the target OS.
Warning: MAXSTACKSIZE is not supported by the target OS
The {$MAXSTACKSIZE} directive is not supported by the target OS.
Error: Illegal state for $WARN directive
Only ON and OFF can be used as state with a {$WARN} compiler directive.
Error: Illegal set packing value
Only 0, 1, 2, 4, 8, DEFAULT and NORMAL are allowed as packset parameters.
Warning: PIC directive or switch ignored
Several targets, such as Windows, do not support nor need PIC, so the PIC directive and switch are ignored.
Warning: The switch ”arg1” is not supported by the currently selected target
Some compiler switches like $E are not supported by all targets.
Warning: Framework-related options are only supported for Darwin/Mac OS X
Frameworks are not a known concept, or at least not supported by FPC, on operating systems other than Darwin/Mac OS X.
Error: Illegal minimal floating point constant precision ”arg1”
Valid minimal precisions for floating point constants are default, 32 and 64, which mean respectively minimal (usually 32 bit), 32 bit and 64 bit precision.
Warning: Overriding name of ”main” procedure multiple times, was previously set to ”arg1”
The name for the main entry procedure is specified more than once. Only the last name will be used.
