13.5 Symbol handling

Error: Identier not found "arg1"

The compiler doesn't know this symbol. Usually happens when you misspel the name of a variable or procedure, or when you forgot to declare a variable.

Fatal: Internal Error in SymTableStack()

An internal error occurred in the compiler; If you encounter such an error, please contact the developers and try to provide an exact description of the circumstances in which the error occurs.

Error: Duplicate identier "arg1"

The identier was already declared in the current scope.

Hint: Identier already dened in arg1 at line arg2

The identier was already declared in a previous scope.

Error: Unknown identier "arg1"

The identier encountered has not been declared, or is used outside the scope where it is dened.

Error: Forward declaration not solved "arg1"

This can happen in two cases:

• This happens when you declare a function (in the interface part, or with a forward directive, but do not implement it.
• You reference a type which isn't declared in the current type block.

Error: Error in type denition

There is an error in your denition of a new array type:

One of the range delimiters in an array declaration is erroneous. For example, Array [1..1.25] will trigger this error.

Error: Forward type not resolved "arg1"

A symbol was forward dened, but no declaration was encountered.

Error: Only static variables can be used in static methods or outside methods

A static method of an object can only access static variables.

Fatal: record or class type expected

The variable or expression isn't of the type record or class.

Error: Instances of classes or objects with an abstract method are not allowed

You are trying to generate an instance of a class which has an abstract method that wasn't overridden.

Warning: Label not dened "arg1"

A label was declared, but not dened.

Error: Label used but not dened "arg1"

A label was declared and used, but not dened.

Error: Illegal label declaration

This error should never happen; it occurs if a label is dened outside a procedure or function.

Error: GOTO and LABEL are not supported (use switch -Sg)

You must compile a program which has labels and goto statements with the -Sg switch. By default, label and goto aren't supported.

Error: Label not found

A goto label was encountered, but the label isn't declared.

Error: identier isn't a label

The identier specied after the goto isn't of type label.

Error: label already dened

You are dening a label twice. You can dene a label only once.

Error: illegal type declaration of set elements

The declaration of a set contains an invalid type denition.

Error: Forward class denition not resolved "arg1"

You declared a class, but you did not implement it.

Hint: Unit "arg1" not used in arg2

The unit referenced in the uses clause is not used.

Hint: Parameter "arg1" not used

The identier was declared (locally or globally) but was not used (locally or globally).

Note: Local variable "arg1" not used

You have declared, but not used a variable in a procedure or function implementation.

Hint: Value parameter "arg1" is assigned but never used

The identier was declared (locally or globally) set but not used (locally or globally).

Note: Local variable "arg1" is assigned but never used

The variable in a procedure or function implementation is declared, set but never used.

Hint: Local arg1 "arg2" is not used

A local symbol is never used.

Note: Private eld "arg1.arg2" is never used

Note: Private eld "arg1.arg2" is assigned but never used

Note: Private method "arg1.arg2" never used

Error: Set type expected

The variable or expression is not of type set. This happens in an in statement.

Warning: Function result does not seem to be set

You can get this warning if the compiler thinks that a function return value is not set. This will not be displayed for assembler procedures, or procedures that contain assembler blocks.

Warning: Type "arg1" is not aligned correctly in current record for C

Arrays with sizes not multiples of 4 will be wrongly aligned for C structures.

Error: Unknown record eld identier "arg1"

The eld doesn't exist in the record/object denition.

Warning: Local variable "arg1" does not seem to be initialized

This message is displayed if the compiler thinks that a variable will be used (i.e. appears in the right-hand-side of an expression) when it was not initialized rst (i.e. appeared in the left-hand side of an assigment)

Warning: Variable "arg1" does not seem to be initialized

This message is displayed if the compiler thinks that a variable will be used (i.e. appears in the right-hand-side of an expression) when it was not initialized rst (i.e. appeared in the left-hand side of an assigment)

Error: identier idents no member "arg1"

This error is generated when an identier of a record, eld, or method is accessed while it is not dened.

Hint: Found declaration: arg1

You get this when you use the -vh switch. In case an overloaded procedure is not found, then all candidate overloaded procedures are listed, with their parameter lists.

Error: Data element too large

You get this when you declare a data element whose size exceeds the prescribed limit (2 Gb on 80386+/68020+ processors)

Error: No matching implementation for interface method "arg1" found

There was no matching method found which could implement the interface method. Check argument types and result type of the methods.

Warning: Symbol "arg1" is deprecated

This means that a symbol (a variable, routine, etc...) which is declared as deprecated is used. Deprecated symbols may no longer be available in newer versions of the unit / library. Usage of this symbol should be avoided as much as possible.

Warning: Symbol "arg1" is not portable

This means that a symbol (a variable, routine, etc...) which is declared as platform is used. This symbol's value, usage and availability is platform specic and should not be used if the source code must be portable.

Warning: Symbol "arg1" is not implemented

This means that a symbol (a variable, routine, etc...) which is declared as unimplemented is used. This symbol is dened, but is not yet implemented on this specic platform.

Error: Can't create unique type from this type

Only simple types like ordinal, oat and string types are supported when redening a type with type newtype = type oldtype;.

Hint: Local variable "arg1" does not seem to be initialized

This message is displayed if the compiler thinks that a variable will be used (i.e. appears in the right-hand-side of an expression) when it was not initialized rst (i.e. appeared in the left-hand side of an assigment)

Hint: Variable "arg1" does not seem to be initialized

This message is displayed if the compiler thinks that a variable will be used (i.e. appears in the right-hand-side of an expression) when it was not initialized rst (i.e. appeared in the left-hand side of an assigment)
